When a communication terminal connects to the Internet via a router, gateway, mobile communication network, etc., the local IP address assigned to the communication terminal may be converted to a global IP address in the router, gateway, mobile communication network, etc. Even if an individual global IP address is assigned to the communication terminal, the relationship between the communication terminal and the global IP address may be variable. For this reason, it is difficult to analyze the global IP addresses of multiple communication terminals that have accessed a web page and accurately estimate the access pattern of each communication terminal.

In a first aspect of the present invention, an information processing device is provided. The information processing device includes, for example, a global IP acquisition unit that acquires first confirmation information indicating that a communication terminal that has requested a management device that manages content distribution to transmit content has received the content, and a global IP address of the communication terminal that transmitted the first confirmation information. The information processing device includes, for example, a communication carrier identification unit that identifies a communication carrier to which a global IP address acquired by the global IP acquisition unit in association with the first confirmation information has been assigned, by referring to a first storage device that stores communication carriers to which each global IP address has been assigned in association with the first confirmation information. The information processing device includes, for example, a command transmission unit that transmits, to the communication terminal, a command to cause the communication terminal to execute a redirect to a predetermined address when the communication carrier identified by the communication carrier identification unit is a predetermined communication carrier.

In the above information processing device, the first confirmation information may be a signal transmitted from the communication terminal to the information processing device by executing, in the communication terminal, an advertisement tag, a beacon tag, or a tracking code received by the communication terminal in association with the reception of the content. In any of the above information processing devices, the content may be at least one of data of a web page, an e-mail, an electronic bulletin board, an SNS page, an image, an audio, and a music, and an advertisement presented in association therewith.

In a second aspect of the present invention, an information acquisition device is provided. The information acquisition device includes, for example, an IP acquisition unit that acquires second confirmation information indicating that a communication terminal that requested a management device that manages content distribution to transmit content has received the content, and an IP address of the communication terminal that transmitted the second confirmation information. The information acquisition device includes, for example, a terminal identification information acquisition unit that acquires terminal identification information of a communication terminal to which an IP address acquired by the IP acquisition unit in association with the second confirmation information is assigned, by referring to (i) terminal identification information that identifies one or more communication terminals, and (ii) a second storage device that stores IP addresses assigned to each communication terminal in association with each other.

In the above information acquisition device, the communication terminal may access the management device via a network and the Internet. The above information acquisition device may send and receive information to and from the communication device using the network. Any of the above information acquisition devices may include an address assignment unit that assigns an IP address to the communication terminal.

Any of the above information acquisition devices may include a time information acquisition unit that acquires time information indicating the time when the second confirmation information was acquired. Any of the above information acquisition devices may include a log information generation unit that generates log information in which the terminal identification information acquired by the terminal identification information acquisition unit and the time information acquired by the time information acquisition unit are associated.

Any of the above information acquisition devices may include an access pattern determination unit that determines an access pattern of a communication terminal to one or more management devices based on multiple log information related to a specific communication terminal generated during a specific period. Any of the above information acquisition devices may include a lifestyle pattern estimation unit that estimates a lifestyle pattern of a user of the communication terminal based on the access pattern of the communication terminal. In the above information acquisition devices, the lifestyle pattern estimation unit may determine a lifestyle pattern of a user of the communication terminal based on whether or not the access pattern of the communication terminal satisfies a predetermined judgment criterion for each of one or more lifestyle patterns. The above information processing device may include a criterion determination unit that determines a judgment criterion based on clustering by unsupervised machine learning.

In any of the above information acquisition devices, the second confirmation information may be a signal transmitted from a communication terminal to the information acquisition device based on a command from any of the information processing devices related to the first aspect above.

An example of the system configuration of a computer 3000 is shown in schematic form.

The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. In the drawings, the same reference numbers may be used to designate the same or similar parts, and duplicate explanations may be omitted.

Figure 1 shows an example of the system configuration of an access analysis system 100. In this embodiment, an example of the access analysis system 100 is described using an example in which the access analysis system 100 detects access from a communication terminal 110 to a content distribution server 120.

When the communication terminal 110 accesses the content distribution server 120, for example, the communication terminal 110 is assigned a local IP address (sometimes referred to as a local IP) or a global IP address (sometimes referred to as a global IP). When it is necessary to distinguish between types of IP addresses in the explanation of the access analysis system 100, the IP address is written as a local IP address or a global IP address. On the other hand, when there is no particular need to distinguish between types of IP addresses, the IP address (either a local IP address or a global IP address) may simply be written as IP.

In this embodiment, the communication terminal 110 is connected to the data communication control server 102 via the network 12. The communication terminal 110 is connected to the data communication control server 102, for example, via a wireless communication network that constitutes part of the network 12. In this embodiment, the data communication control server 102 is connected to the communication network 10. The data communication control server 102 can function as a connection point that connects the communication network 10 and the network 12. This allows the communication terminal 110 to send and receive information between various devices connected to the communication network 10, via the communication network 10 and the network 12. The communication terminal 110 can access the content distribution server 120, for example, via the communication network 10 and the network 12.

In this embodiment, when the communication terminal 110 transmits and receives information to and from other information processing devices via the communication network 10, the communication of the communication terminal 110 is controlled using a global IP address assigned to the data communication control server 102. Examples of other information processing devices include the access detection server 104, the content distribution server 120, and the advertisement distribution system 130.

Here, multiple data communication control servers 102 may be connected to a single network 12. In this case, a different global IP is assigned to each of the multiple data communication control servers 102.

The communication terminal 110 can change the data communication control server 102 to which it is connected according to any condition. In one embodiment, for example, if the length of connection time between the communication terminal 110 and the currently connected data communication control server 102 exceeds a predetermined value, the communication terminal 110 changes the connection destination and connects to another data communication control server 102. In another embodiment, for example, if the communication terminal 110 moves and the physical distance between the communication terminal 110 and the currently connected data communication control server 102 exceeds a predetermined value, the communication terminal 110 changes the connection destination and connects to another data communication control server 102 that is closer than the currently connected data communication control server 102.

The communication between the data communication control server 102 and the communication terminal 110 is controlled by using the local IP address assigned to the communication terminal 110 by the data communication control server 102. Therefore, the data communication control server 102 can identify the communication terminal 110 that has accessed the other information processing device.

On the other hand, the other information processing device cannot continuously and accurately identify the communication terminal 110 that is accessing the other information processing device by using the IP address of the communication terminal 110 that has accessed the other information processing device via the data communication control server 102. The reason for this is as follows.

(When a local IP is assigned to the communication terminal 110)
The data communication control server 102 may change the local IP assigned to the communication terminal 110 at any timing. For example, the data communication control server 102 changes the local IP assigned to the communication terminal 110 every time the communication terminal 110 makes a connection request to the data communication control server 102. The data communication control server 102 may also change the local IP assigned to the communication terminal 110 periodically.

In addition, when two or more communication terminals 110 communicate with other information processing devices via a single data communication control server 102 at the same time, the data communication control server 102 assigns, for example, different local IPs to each of the two or more communication terminals 110. The data communication control server 102 converts the local IPs assigned to each of the two or more communication terminals 110 into, for example, a global IP assigned to the data communication control server 102 using known technologies such as NAT (Network Address Translation) and NAPT (Network Address Port Translation) (the term NAT processing is sometimes used as a general term for information processing such as NAT and NAPT).

The other information processing device can obtain the global IP of the communication terminal 110 that has accessed the other information processing device via the data communication control server 102. However, as described above, the global IP is originally an IP address assigned to the data communication control server 102 to which the communication terminal 110 is connected. Therefore, the other information processing device cannot continuously check whether the communication is from one communication terminal 110 by using the global IP of the communication terminal 110 that has accessed the information processing device.

(When a global IP is assigned to the communication terminal 110)
In the above example, the reason why it is difficult for the other information processing device to continuously identify the communication terminal 110 that is accessing the information processing device has been explained by taking as an example a case where each of one or more communication terminals 110 exchanges information with the other information processing device using a global IP assigned to the data communication control server 102 to which the communication terminal 110 is connected. In another embodiment, a global IP may be directly assigned to each of one or more communication terminals 110. For example, as the transition from IPv4 to IPv6 progresses, an individual global IP may be assigned to each terminal.

In this case, in communication between the communication terminal 110 and the other information processing device, a different global IP may be assigned for each communication path. For example, a different global IP may be used when a specific communication terminal 110 connects to the first data communication control server 102 and when the specific communication terminal 110 connects to the second data communication control server 102. In this way, even in an IPv6 environment, the correspondence between the communication terminal 110 and the IP address is not always fixed. Therefore, it is difficult for the other information processing device to continuously identify access from a specific communication terminal 110 based on the global IP of the communication terminal 110 that accesses the information processing device.

(Outline of this embodiment)
In contrast, according to the present embodiment, the access analysis system 100 uses mechanisms such as advertisement distribution and Web beacons (which may also be referred to as tracking pixels, tracking codes, etc.) to cause the communication terminal 110 to transmit a signal (which may also be referred to as a reception confirmation signal) to the access detection server 104 when the communication terminal 110 accesses the content distribution server 120 or the advertisement distribution system 130. This allows the access detection server 104 to detect access by the communication terminal 110 to the content distribution server 120 or the advertisement distribution system 130.

At this time, the IP address of the sender of the receipt confirmation signal is a global IP, and as described above, it is not easy to link the global IP to the terminal identification information of the communication terminal 110. Therefore, according to this embodiment, when the access detection server 104 detects access by the communication terminal 110 to the content distribution server 120 or the advertisement distribution system 130, the access detection server 104 transmits a command (sometimes called a redirect notification) to the communication terminal 110 to redirect the above-mentioned receipt confirmation signal to the data communication control server 102.

When the communication terminal 110 receives the redirect notification, the communication terminal 110 transmits an acknowledgment signal to the data communication control server 102. At this time, the address of the sender of the acknowledgment signal is the IP address assigned to the communication terminal 110. Since the data communication control server 102 is aware of the correspondence between the IP assigned to the communication terminal 110 and the terminal identification information of the communication terminal 110, the data communication control server 102 can identify the communication terminal 110 that transmitted the acknowledgment signal.

In this embodiment, the data communication control server 102 transmits to the access recording server 103 an access log that associates the time of receipt of the receipt confirmation signal with the terminal identification information of the communication terminal 110 that transmitted the receipt confirmation signal. The access recording server 103 stores the access log received from the data communication control server 102.

In this embodiment, an overview of the access analysis system 100 is described using as an example a case where the access record server 103 is connected to the data communication control server 102 via the network 12. However, the access record server 103 is not limited to this embodiment. In other embodiments, the access record server 103 is connected to the data communication control server 102 via the communication network 10. In still other embodiments, the access record server 103 may be installed on the same device as the data communication control server 102.

When data on the access of a particular communication terminal 110 is accumulated over a certain period of time, a particular pattern (sometimes referred to as an access pattern) in the way that particular communication terminal 110 accesses the content distribution server 120 may be found by analyzing the data. In addition, when data on the access of multiple communication terminals 110 is accumulated over a certain period of time, a correlation may be found between the particular access pattern and the life or behavior pattern (sometimes referred to as a lifestyle pattern) of the user of the communication terminal 110. Examples of lifestyle patterns include wake-up time, bedtime, working hours, commuting hours, and whether or not the user has a fixed Internet line contract at home or at work.

The lifestyle patterns of each user are used, for example, when determining the attributes of the user in advertisement delivery. For example, the advertisement delivery system 130 can use information about the lifestyle patterns of each user to deliver advertisements related to fixed Internet lines to users who are likely not yet contracted for a fixed Internet line.

As described above, according to this embodiment, the access analysis system 100 can, for example, identify access patterns to servers that provide various services for each of one or more communication terminals 110. In particular, the access analysis system 100 can analyze the access patterns of each of one or more communication terminals 110 without compromising the confidentiality of communications.

(An example of another embodiment)
In this embodiment, the overview of the access analysis system 100 has been described by taking as an example a case where the redirect notification is a command for directly transmitting an acknowledgment signal to the data communication control server 102. However, the access analysis system 100 is not limited to this embodiment. In other embodiments, the redirect notification may be a command for indirectly transmitting an acknowledgment signal to the data communication control server 102.

In this case, when the communication terminal 110 receives the redirect notification, the communication terminal 110, for example, first transmits an acknowledgment signal to another server different from the data communication control server 102. When the other server receives the acknowledgment signal, the other server transfers the acknowledgment signal to the data communication control server 102. The other server may be provided on a local network (for example, on network 12) or on a global network (for example, on communication network 10). This allows the data communication control server 102, for example, to receive or acquire both redirects from mobile lines and redirects from fixed lines via the other server.

(Overview of the access analysis system 100)
1 shows an example of a system configuration of an access analysis system 100. In this embodiment, the access analysis system 100 includes a data communication control server 102, an access recording server 103, and an access detection server 104. The access analysis system 100 may include a plurality of data communication control servers 102. The access analysis system 100 may further include at least one of a communication terminal 110, a content distribution server 120, and an advertisement distribution system 130. In this embodiment, the advertisement distribution system 130 includes an SSP server 132, a DSP server 134, and an advertisement server 136.

According to this embodiment, an example of the access analysis system 100 will be described taking as an example a case where the access detection server 104 detects access from the communication terminal 110 to the content distribution server 120. In this embodiment, when the communication terminal 110 requests the content distribution server 120 to transmit content, the advertisement distribution system 130 distributes advertisements using the content distributed by the content distribution server 120 as a medium by third-party distribution (sometimes referred to as Third Party Ad Serving, 3PAS).

According to one embodiment, a beacon tag is embedded in the advertisement delivered by the advertisement delivery system 130. In this case, the access detection server 104 detects access from the communication terminal 110 to the content delivery server 120, for example, when (i) the communication terminal 110 receives content from the content delivery server 120, an advertisement tag is executed in the communication terminal 110, and (ii) the advertisement delivery system 130 delivers an advertisement to the communication terminal 110 in response to the execution of the advertisement tag, and the beacon tag in the advertisement is executed in the communication terminal 110.

According to another embodiment, an advertisement tag is embedded in the content distributed by the content distribution server 120. In this case, the access detection server 104 detects access from the communication terminal 110 to the content distribution server 120, for example, when the communication terminal 110 receives content from the content distribution server 120 and the advertisement tag is executed in the communication terminal 110.

In yet another embodiment, a beacon tag (sometimes called a tracking code) is embedded in the content distributed by the content distribution server 120. In this case, the access detection server 104 detects access from the communication terminal 110 to the content distribution server 120, for example, when the communication terminal 110 receives content from the content distribution server 120 and the beacon tag is executed in the communication terminal 110.

As described above, in this embodiment, the communication terminal 110 is connected to the communication network 10 via the network 12. In addition, multiple data communication control servers 102 may be connected to a single network 12. For example, if the user of the communication terminal 110 has signed a contract for a fixed Internet line at home, the communication terminal 110 is connected to the communication network 10 via the first data communication control server 102 while the user of the communication terminal 110 is staying at home. On the other hand, the communication terminal 110 is connected to the communication network 10 via the second data communication control server 102 while the user of the communication terminal 110 is out. The first data communication control server 102 and the second data communication control server 102 may be the same or different.

In this embodiment, the communication network 10 transmits information between multiple devices. The communication network 10 may be a transmission path for wired communication, a transmission path for wireless communication, or a combination thereof. The communication network 10 may be the Internet, a dedicated line, a wireless communication network, or a combination thereof. The communication network 10 may include a P2P network such as an ad-hoc network.

The communication method in the wireless communication network may be a mobile communication method or a wireless data communication method. Examples of the mobile communication method include the 3G method, the LTE method, the 4G method, and the 5G method. Examples of the wireless data communication method include a wireless PAN method such as ZigBee (registered trademark) or Bluetooth (registered trademark), a wireless LAN method such as WiFi (registered trademark), a wireless MAN method such as WiMAX (registered trademark), and a wireless WAN method.

In this embodiment, the network 12 transmits information between multiple devices. The network 12 may be a transmission path for wired communication, a transmission path for wireless communication, or a combination of these. The network 12 may be a local network.

The network 12 connects, for example, the communication terminal 110 to the Internet, which constitutes at least a part of the communication network 10. Communications in the network 12 are controlled by the data communication control server 102. As described above, communications between the data communication control server 102 and the communication terminal 110 are controlled by the IP assigned to the communication terminal 110 by the data communication control server 102. The IP assigned to the communication terminal 110 by the data communication control server 102 may be a local IP or a global IP.

(Overview of each part of the access analysis system 100)
In this embodiment, the data communication control server 102 controls data communication in the network 12. Each of the one or more data communication control servers 102 may transmit and receive information to and from each of the one or more communication terminals 110 using the network 12. The data communication control server 102 may be a device for connecting different networks and relaying communications between the networks. Specifically, for example, the data communication control server 102 is a network device such as a router or a gateway.

As described above, in one embodiment, the data communication control server 102 assigns a local IP to each of the one or more communication terminals 110. In another embodiment, a global IP is assigned to each of the one or more communication terminals 110.

(When the IP address directly assigned to the communication terminal 110 is a local IP address)
In one embodiment, the data communication control server 102 assigns local IPs to one or more communication terminals 110 that use the network 12, and uses the local IPs to control communications within the network 12. The data communication control server 102 also executes NAT processing to convert the local IPs assigned to the one or more communication terminals 110 into global IPs assigned to the data communication control server 102. This allows the data communication control server 102 to connect one or more communication terminals 110 connected to the network 12 to the Internet.

As described above, in this embodiment, the data communication control server 102 receives an acknowledgment signal from the communication terminal 110 when the communication terminal 110 accesses the content distribution server 120 or the advertisement distribution system 130. In this embodiment, communication between the data communication control server 102 and the communication terminal 110 is controlled by a local IP, so the data communication control server 102 can obtain the local IP (sometimes referred to as a local IP address obtained in relation to the acknowledgment signal) of the communication terminal 110 that sent the acknowledgment signal. The above-mentioned acknowledgment signal may be a signal sent to the data communication control server 102 in accordance with a redirect notification sent to the communication terminal 110 by the access detection server 104.

In addition, in this embodiment, the data communication control server 102 refers to a database (not shown in FIG. 1) that stores (i) information identifying each of the one or more communication terminals 110 (which may be referred to as terminal identification information, terminal ID, etc.) and (ii) local IP addresses assigned to each of the one or more communication terminals 110 in association with each other, to acquire the terminal identification information of the communication terminal 110 to which the local IP address acquired in association with the receipt confirmation signal has been assigned. The data communication control server 102 may store the time of receipt of the receipt confirmation signal in association with the terminal identification information of the communication terminal 110 that transmitted the receipt confirmation signal.

(When the IP address directly assigned to the communication terminal 110 is a global IP address)
In another embodiment, the data communication control server 102 assigns a global IP to each of one or more communication terminals 110 that use the network 12, and uses the global IP to control communications within the network 12. The data communication control server 102 can also use the global IP to connect one or more communication terminals 110 connected to the network 12 to the Internet.

In this embodiment, the data communication control server 102 receives a receipt confirmation signal from the communication terminal 110 when the communication terminal 110 accesses the content distribution server 120 or the advertisement distribution system 130. The receipt confirmation signal may be a signal sent to the data communication control server 102 in accordance with a redirect notification sent to the communication terminal 110 by the access detection server 104.

In addition, in this embodiment, the data communication control server 102 refers to a database that stores (i) information identifying each of the one or more communication terminals 110 and (ii) a global IP assigned to each of the one or more communication terminals 110 in association with each other, and acquires the terminal identification information of the communication terminal 110 to which the global IP acquired in association with the receipt confirmation signal is assigned. The data communication control server 102 may store the time of receipt of the receipt confirmation signal in association with the terminal identification information of the communication terminal 110 that transmitted the receipt confirmation signal.

In this embodiment, the details of the access analysis system 100 are mainly described using the example of the IP directly assigned to the communication terminal 110 being a local IP. However, a person skilled in the art who has read the description of this specification can understand that even if the IP directly assigned to the communication terminal 110 is a global IP, information processing can be performed in the same manner as when the IP directly assigned to the communication terminal 110 is a local IP, except that (i) the data communication control server 102 determines whether or not to perform NAT processing, and (ii) instead of identifying the terminal identification information from the local IP using a database that stores information indicating the correspondence between the local IP and the terminal identification information of each of one or more communication terminals 110, the terminal identification information is identified from the global IP using a database that stores information indicating the correspondence between the global IP and the terminal identification information of each of one or more communication terminals 110. Details of the data communication control server 102 will be described later.

(Terminal Identification Information)
The details of the terminal identification information are not particularly limited as long as the access analysis system 100 can uniquely identify each of the one or more communication terminals 110. Examples of the terminal identification information include (a) an ID unique to the communication terminal, (b) an ID unique to the subscriber assigned to each subscriber of the communication terminal (sometimes referred to as a subscriber-specific ID. Also, depending on the communication carrier, it may be referred to as a terminal manufacturing number, a user ID, an i-mode (registered trademark) ID, a subscriber ID, an EZ number, a terminal serial number, etc.), (c) identification information assigned to the user of the communication terminal 110 by various service providers, (d) unique identification information assigned to the communication terminal 110 by various service providers (sometimes referred to as a unique ID), and (e) information obtained by encrypting these.

Examples of an ID unique to a communication terminal include (i) an ID assigned to the communication terminal 110 by the manufacturer of the communication terminal 110, (ii) an ID unique to the communication terminal recorded on various SIM (Subscriber Identity Module) cards, (iii) a BD address (sometimes referred to as BD_ADDR, etc.) for identifying a Bluetooth (registered trademark) compatible device, and (iv) an address for identifying a ZigBee (registered trademark) compatible device. Examples of an ID assigned to the communication terminal 110 by the manufacturer of the communication terminal 110 include a UDID (Unique Device Identifier), an Android (registered trademark) ID, a MAC address, and a serial number.

Examples of identification information assigned by various service providers to users of the communication terminal 110 include a member ID, a telephone number, an email address, an IP address, a web service account, and a web service login ID. Examples of unique IDs include information managed using an HTTP cookie (sometimes simply referred to as a cookie). Examples of information managed using a cookie include identification information for identifying a communication terminal, identification information for identifying a session, and the like.

The terminal identification information may be a hashed IMSI or a hashed MAC address. This allows the access patterns of each communication terminal to be analyzed without identifying individual users.

In this embodiment, the access record server 103 stores various types of information. In one embodiment, the access record server 103 stores various types of information used in information processing in the access analysis system 100. In another embodiment, the access record server 103 stores various types of information generated in information processing in the access analysis system 100. Details of the access record server 103 will be described later.

In this embodiment, the access detection server 104 detects access by the communication terminal 110 to the content distribution server 120 or the advertisement distribution system 130. As described above, in this embodiment, the access detection server 104 receives a receipt confirmation signal from the communication terminal 110 when the communication terminal 110 accesses the content distribution server 120 or the advertisement distribution system 130. Since communication between the access detection server 104 and the communication terminal 110 is controlled by a global IP, the access detection server 104 can obtain the global IP (sometimes referred to as a global IP address obtained in association with the receipt confirmation signal) of the communication terminal 110 that transmitted the receipt confirmation signal.

In addition, in this embodiment, the access detection server 104 identifies the telecommunications carrier to which the global IP address acquired in association with the receipt confirmation signal has been assigned. For example, the access detection server 104 refers to a database (not shown) that stores (i) one or more global IP addresses and (ii) information for identifying the telecommunications carrier to which each global IP address has been assigned, in association with each other, to identify the telecommunications carrier to which the global IP address acquired in association with the receipt confirmation signal has been assigned. Examples of information for identifying the telecommunications carrier include the name of the telecommunications carrier and identification information for uniquely identifying the telecommunications carrier.

The access detection server 104 may refer to a database (not shown) that stores, for each of one or more telecommunications carriers, information for identifying the telecommunications carrier in association with information for sending various notifications or information to the telecommunications carrier (sometimes referred to as the address of the telecommunications carrier), and obtain the address of the telecommunications carrier to which the global IP address obtained in association with the receipt confirmation signal has been assigned.

The address of the telecommunications carrier may be used as information for identifying the telecommunications carrier. In this case, the access detection server 104, for example, refers to a database (not shown) that stores (i) one or more global IP addresses and (ii) the addresses of the telecommunications carriers to which each global IP address is assigned, in association with each other, to acquire the address of the telecommunications carrier to which the global IP address acquired in association with the reception confirmation signal is assigned.

In this embodiment, the access detection server 104 transmits to the communication terminal 110 a command to cause the communication terminal 110 to execute a redirect to a predetermined address. For example, if the above-mentioned specified communication carrier is a predetermined communication carrier, the access detection server 104 transmits the above-mentioned command to the communication terminal 110. According to one embodiment, the access detection server 104 transmits to the communication terminal 110 that transmitted the receipt confirmation signal a redirect notification to cause the communication terminal 110 to redirect the receipt confirmation signal to the address of the above-mentioned communication carrier. According to another embodiment, if the above-mentioned specified communication carrier is a predetermined communication carrier, the access detection server 104 transmits to the communication terminal 110 that transmitted the receipt confirmation signal a redirect notification to cause the communication terminal 110 to redirect the receipt confirmation signal to a default address (e.g., an address indicating the data communication control server 102). Details of the access detection server 104 will be described later.

In this embodiment, the communication terminal 110 may be any device capable of transmitting and receiving information to and from other information processing devices, and the details thereof are not particularly limited. The communication terminal 110 may support multiple communication methods. For example, the communication terminal supports both mobile communication methods such as the 3G method, the LTE method, and the 4G method, and wireless communication methods such as the wireless LAN method and the wireless MAN method. The communication terminal 110 may be a mobile terminal. Examples of the mobile terminal include a mobile phone, a smartphone, a PDA, a tablet, a notebook computer or a laptop computer, and a wearable computer.

In this embodiment, the content distribution server 120 manages the distribution of various types of content. The content distribution server 120 accepts a request for transmission of specific content from the communication terminal 110. The content distribution server 120 transmits the specific content to the communication terminal 110 that transmitted the request.

The content may be digital data, and there are no particular limitations on the type and content. Examples of content include at least one of the following data: web pages, e-mails, electronic bulletin boards, SNS pages, images, sounds, and music, as well as advertisements presented in association with these. The e-mails may be HTML mail. Examples of advertisements presented in association with the above various data include advertisements presented to the user of the communication terminal 110 using at least a portion of the various data as a medium.

The content may have an advertising space set therein. The content may have an advertising tag, a beacon tag, or a tracking code arranged therein. The advertising tag, the beacon tag, or the tracking code may be created, for example, by Javascript (registered trademark).

The advertisement tag, beacon tag, or tracking code placed in the content is received by the communication terminal 110 when the communication terminal 110 receives the content. In addition, the advertisement tag, beacon tag, or tracking code placed in the content is executed by the communication terminal 110 when the communication terminal 110 executes the content.

In this embodiment, the advertisement distribution system 130 distributes advertisements. The advertisement may be information that is notified to the user of the communication terminal 110, and the content of the advertisement is not particularly limited. The advertisement may be information about a product or service of the advertisement provider (sometimes referred to as an advertiser). The information about the product or service may be discount information for the product or service (sometimes referred to as coupon information), event announcement information, etc.

As another example of information related to a product or service, if the advertising provider is a public transportation company, the advertising information may be information about service suspensions, delays, traffic congestion, etc. Furthermore, if the advertising provider is a business or government agency that provides weather forecast services, the advertising information may be warnings or alerts regarding localized heavy rain, lightning strikes, wind gusts, etc. The advertising information may be information related to disasters. The advertising information may be information related to a specific region.

In this embodiment, the SSP server 132 acquires an advertisement request from the communication terminal 110. The advertisement request is sent from the communication terminal 110 to the SSP server 132, for example, when the communication terminal 110 executes an advertisement tag placed in content.

As described above, in connection with receiving the content, the communication terminal 110 receives the advertisement tag, beacon tag, or tracking code placed in the content. In addition, when the communication terminal 110 executes the content, the advertisement tag, beacon tag, or tracking code is also executed.

The advertisement request includes, for example, (i) information about the communication terminal 110, such as the domain, IP address, OS, and browser of the communication terminal 110, and (ii) information about the advertisement, such as the domain of the content distribution server 120, the content category, an advertisement space ID that identifies the advertisement display area, and the advertisement size. If the browser of the communication terminal 110 allows the reading and writing of third-party cookies and the SSP server 132 has written a cookie in the past, the header of the advertisement request may include a cookie related to the domain of the SSP server 132.

If the IP directly assigned to the communication terminal 110 is a local IP, the IP address of the communication terminal 110 included in the advertisement request is, for example, a global IP generated by NAT processing. If the IP directly assigned to the communication terminal 110 is a global IP, the IP address of the communication terminal 110 included in the advertisement request is, for example, a global IP directly assigned to the communication terminal 110.

In this embodiment, in response to receiving an advertisement request from the communication terminal 110, the SSP server 132 generates a bidding request (sometimes referred to as a bid request) and transmits the bidding request to one or more DSP servers 134. The SSP server 132 obtains a bidding response (sometimes referred to as a bid response) to the above-mentioned bidding request from each of the one or more DSP servers 134. The SSP server 132 executes an auction process to determine a winning DSP from among the one or more DSP servers 134 that has won the right to distribute the advertisement. The SSP server 132 transmits the advertisement tag of the winning DSP to the communication terminal 110 as a response to the advertisement request.

In this embodiment, the DSP server 134 provides a demand-side platform (DSP) that centrally manages multiple ad exchanges or ad networks. The DSP server 134 manages, for example, advertisements provided by one or more advertisement servers 136. In this embodiment, the DSP server 134 cooperates with the SSP server 132 to realize RTB (Real-Time Bidding) transactions. In this embodiment, each of the one or more DSP servers 134 executes an auction for multiple advertisements managed by each of the one or more DSP servers 134 in response to a bid request from the SSP server 132. Then, information regarding the winning advertisement of the above auction is transmitted to the SSP server 132 as a bid response.

In this embodiment, the advertisement server 136 stores advertisement data and manages the distribution of advertisements. The advertisement server 136 distributes advertisement information to the communication terminal 110 in response to a request from the communication terminal 110. Note that the method of distributing advertisements is not particularly limited. In other embodiments, the advertisement server 136 may distribute advertisement information to the communication terminal 110 in response to a request from the DSP server 134.

The advertising information may be any information that is notified to the user of the communication terminal 110, and the content of the advertisement is not particularly limited. The advertising information may be information about a product or service of the advertisement provider (sometimes referred to as an advertiser). The information about the product or service may be discount information about the product or service (sometimes referred to as coupon information), event announcement information, etc.

As another example of information related to a product or service, if the advertising provider is a public transportation company, the advertising information may be information about service suspensions, delays, traffic congestion, etc. Furthermore, if the advertising provider is a business or government agency that provides weather forecast services, the advertising information may be warnings or alerts regarding localized heavy rain, lightning strikes, wind gusts, etc. The advertising information may be information related to disasters.

(Specific configuration of each part of the access analysis system 100)
Each part of the access analysis system 100 may be realized by hardware, software, or hardware and software. At least a part of each part of the access analysis system 100 may be realized by a single server, or by multiple servers. At least a part of each part of the access analysis system 100 may be realized on a virtual server or a cloud system. At least a part of each part of the access analysis system 100 may be realized by a personal computer or a mobile terminal. Examples of the mobile terminal include a mobile phone, a smartphone, a PDA, a tablet, a notebook computer or a laptop computer, and a wearable computer. The access analysis system 100 may store information using a distributed ledger technology such as a blockchain or a distributed network.

When at least some of the components constituting the access analysis system 100 are realized by software, the components realized by the software may be realized by starting software or a program that defines the operation of the components in an information processing device of a general configuration. The information processing device may include (i) a data processing device having a processor such as a CPU or GPU, a ROM, a RAM, a communication interface, etc., (ii) an input device such as a keyboard, a touch panel, a camera, a microphone, various sensors, a GPS receiver, etc., (iii) an output device such as a display device, a speaker, a vibration device, etc., and (iv) a storage device such as a memory or a HDD (including an external storage device). In the information processing device, the data processing device or storage device may store the software or program. The software or program is executed by a processor to cause the information processing device to perform the operation defined by the software or program. The software or program may be stored in a non-transitory computer-readable recording medium.

The above software or program may be a program for causing a computer to function as the access analysis system 100 or a part thereof. The above software or program may be a program for causing a computer to execute information processing in the access analysis system 100 or a part thereof.

In one embodiment, the information processing may be an information processing method having the following steps. The subject of each step of the information processing method may be a computer. The information processing method may, for example, have a global IP acquisition step of acquiring first confirmation information indicating that a communication terminal that requested content from a management device that manages content distribution has received the content, and a global IP address of the communication terminal that transmitted the first confirmation information. The information processing method may, for example, have a communication carrier identification step of identifying a communication carrier to which a global IP address acquired by the global IP acquisition unit in association with the first confirmation information has been assigned, by referring to a first storage device that stores communication carriers to which each global IP address has been assigned in association with the first confirmation information. The information processing method may, for example, have a command transmission step of transmitting, to the communication terminal, a command to execute a redirect to a predetermined address when the communication carrier identified by the communication carrier identification unit is a predetermined communication carrier.

In another embodiment, the information processing may be an information acquisition method having the following steps. The subject of each step of the information acquisition method may be a computer. The information acquisition method may, for example, have a local IP acquisition step of acquiring second confirmation information indicating that a communication terminal that requested content from a management device that manages content distribution has received the content, and a local IP address of the communication terminal that transmitted the second confirmation information. The information acquisition method may, for example, have a terminal identification information acquisition step of acquiring terminal identification information of a communication terminal to which the local IP address acquired in association with the second confirmation information in the local IP acquisition step is assigned, by referring to (i) terminal identification information that identifies one or more communication terminals and (ii) a second storage device that stores the local IP addresses assigned to each communication terminal in association with each other.

The data communication control server 102 may be an example of an information acquisition device. The access detection server 104 may be an example of an information processing device. The content distribution server 120 may be an example of a management device. The content distributed by the content distribution server 120 may be an example of content. The advertisement distribution system 130 may be an example of a management device. The advertisement distributed by the advertisement distribution system 130 may be an example of content. The reception confirmation signal transmitted from the communication terminal 110 to the access detection server 104 may be an example of first confirmation information. The reception confirmation signal transmitted from the communication terminal 110 to the data communication control server 102 may be an example of second confirmation information.

(An example of another embodiment)
In this embodiment, the details of the access analysis system 100 have been described by taking as an example a case where advertisements are distributed by so-called third-party ad serving (sometimes referred to as 3PAS). Specifically, according to this embodiment, the distribution of advertisements is managed by a server different from a server that manages the distribution of a medium on which the advertisement is displayed. However, the access analysis system 100 is not limited to this embodiment. In other embodiments, a server that manages the distribution of a medium may manage the distribution of advertisements displayed on the medium.

In this embodiment, the overview of the access analysis system 100 has been described using as an example a case where the redirect notification is a command to directly send a receipt confirmation signal to the data communication control server 102. However, the access analysis system 100 is not limited to this embodiment.

In another embodiment, the redirect notification may be a command to indirectly transmit the receipt confirmation signal to the data communication control server 102. In this case, when the communication terminal 110 receives the redirect notification, the communication terminal 110, for example, temporarily transmits the receipt confirmation signal to another server different from the data communication control server 102. When the other server receives the receipt confirmation signal, the other server transfers the receipt confirmation signal to the data communication control server 102. The other server may be provided on a local network (for example, on network 12) or on a global network (for example, on communication network 10). This allows, for example, the data communication control server 102 to receive or acquire both redirects from mobile lines and redirects from fixed lines via the other server.

The receipt confirmation signal includes, for example, identification information for uniquely identifying the communication terminal 110 that transmitted the receipt confirmation signal. In one embodiment, when the IP directly assigned to the communication terminal 110 is a local IP, the identification information includes a global IP and a local IP assigned to the communication terminal 110, and information indicating the transmission time or reception time of the receipt confirmation signal. In another embodiment, when the IP directly assigned to the communication terminal 110 is a global IP, the identification information includes a global IP assigned to the communication terminal 110, and information indicating the transmission time or reception time of the receipt confirmation signal.

Figure 2 shows an example of information processing in the access analysis system 100. An example of processing in which the access detection server 104 detects access from the communication terminal 110 to the content distribution server 120 is explained using Figure 2.

In this embodiment, the web page 20 includes a content body 22 and an advertisement space 24. Furthermore, an advertisement tag 26 is arranged in the advertisement space 24. In this embodiment, the advertisement 30 includes an advertisement body 32 and a beacon tag 34. The beacon tag may be a command for loading an extremely small image or a transparent image (sometimes called a beacon image). The above command is created, for example, by Javascript (registered trademark).

According to this embodiment, first, in step 201 (step may be abbreviated as "S"), the browser of the communication terminal 110 accesses the content distribution server 120 and transmits a content distribution request to the content distribution server 120. The content distribution request requests, for example, data of the web page 20 as content.

In S202, the content distribution server 120 transmits data of the web page 20 to the communication terminal 110. In S203, when the browser of the communication terminal 110 executes the web page 20, the advertisement tag 26 is also executed, and an impression of the advertisement space 24 is generated. In S204, the browser of the communication terminal 110 transmits an advertisement request to the SSP server 132.

In S205, the SSP server 132 generates a bid request and transmits the bid request to one or more DSP servers 134. In S206, the DSP server 134 extracts advertisements to be displayed in the advertisement space 24 from among the multiple advertisements stored in the advertisement server 136. For example, the DSP server 134 extracts advertisements to be displayed in the advertisement space 24 based on the attributes of the user of the communication terminal 110. The DSP server 134 determines a bid amount and transmits a bid response including information indicating the bid amount to the SSP server 132.

In S207, the SSP server 132 conducts an auction and determines a winning DSP based on one or more bid responses sent from one or more DSP servers 134. The SSP server 132 sends the advertising tag of the winning DSP to the communication terminal 110.

In S208, the browser of the communication terminal 110 uses the advertisement tag sent from the SSP server 132 to send an advertisement request to the DSP server 134. The DSP server 134 transfers the advertisement request to the advertisement server 136 that manages the advertisement data. In S209, the advertisement server 136 sends the advertisement 30 to the communication terminal 110.

In S210, when the browser of the communication terminal 110 executes the advertisement 30, the beacon tag 34 is also executed, and the browser of the communication terminal 110 transmits a request to transmit a beacon image to the access detection server 104. The transmission request functions as the reception confirmation signal described above. This allows the access detection server 104 to detect that the communication terminal 110 has accessed the content distribution server 120 and received the content.

In S211, the access detection server 104 transmits a beacon image to the communication terminal 110. The browser of the communication terminal 110 displays a web page 20 including the beacon image and the advertisement on the display of the communication terminal 110.

In addition, in S211, the access detection server 104 transmits a redirection notification to the communication terminal 110 (not shown). As described above, the redirection notification includes an instruction to the communication terminal 110 to redirect the transmission request as the above-mentioned reception confirmation signal to the data communication control server 102. This allows the data communication control server 102 to detect that the communication terminal 110 has accessed the content distribution server 120 and received the content.

Figure 3 shows an example of information processing in the access analysis system 100. In this embodiment, an example of information processing in the access analysis system 100 is described using an example in which the IP directly assigned to the communication terminal 110 is a local IP. For example, using Figure 3, an example of processing in which the access detection server 104 detects access from the communication terminal 110 to the content distribution server 120 and an example of processing in which the data communication control server 102 generates an access log are described.

According to this embodiment, first, in S312, the communication terminal 110 transmits a content distribution request to the content distribution server 120 via the data communication control server 102. Between the data communication control server 102 and the communication terminal 110, the source of the content distribution request is represented by the local IP assigned to the communication terminal 110. The data communication control server 102 rewrites the source of the content distribution request to the global IP assigned to the data communication control server 102, and then transmits the content distribution request to the content distribution server 120.

At S314, the content distribution server 120 transmits the content to the communication terminal 110. Between the data communication control server 102 and the content distribution server 120, the destination of the content is represented by the global IP assigned to the data communication control server 102. The data communication control server 102 rewrites the destination of the content to the local IP assigned to the communication terminal 110, and then transmits the content to the communication terminal 110.

Next, in S322, when the communication terminal 110 receives the content and executes the content, the communication terminal 110 transmits an advertisement request to the advertisement distribution system 130. The data communication control server 102 rewrites the IP address of the sender of the advertisement request using a procedure similar to that described above.

At S324, the advertisement distribution system 130 transmits an advertisement to the communication terminal 110. The data communication control server 102 rewrites the IP address of the destination of the advertisement using a procedure similar to that described above.

Next, in S332, when the communication terminal 110 receives the advertisement and executes the advertisement, the communication terminal 110 transmits a request to transmit a beacon image to the access detection server 104. The data communication control server 102 rewrites the IP address of the sender of the transmission request using a procedure similar to that described above.

At S334, the access detection server 104 transmits a beacon image to the communication terminal 110. The data communication control server 102 rewrites the IP address of the transmission destination of the beacon image by a procedure similar to that described above. The access detection server 104 also transmits a redirection notification to the communication terminal 110. As described above, the redirection notification includes an instruction to cause the communication terminal 110 to redirect the transmission request as the above-mentioned reception confirmation signal to the data communication control server 102.

Next, in S342, the communication terminal 110 transmits a transmission request as the above-mentioned reception confirmation signal to the data communication control server 102 in accordance with the redirect notification received from the access detection server 104. At this time, the source of the redirected transmission request is represented by the local IP assigned to the communication terminal 110.

In S344, the data communication control server 102 transmits an HTTP200OK response code to the communication terminal 110. In addition, in S346, the data communication control server 102 transfers the redirected transmission request to the advertisement distribution system 130.

Then, in S350, the communication terminal 110 executes a content display process. In S360, the data communication control server 102 refers to a database that stores local IPs and terminal IDs in association with each other, and acquires the terminal ID of the communication terminal 110 that has transmitted the above transmission request, which is associated with the local IP of the communication terminal 110 that transmitted the above transmission request. The data communication control server 102 generates an access log by associating the reception time of the above transmission request with the terminal ID of the communication terminal 110 that transmitted the above transmission request. The data communication control server 102 transmits the access log to the access record server 103. The access record server 103 stores the access log received from the data communication control server 102.

(An example of another embodiment)
In the present embodiment, the details of the information processing in the access analysis system 100 have been described by taking as an example a case where the IP directly assigned to the communication terminal 110 is a local IP. However, the access analysis system 100 is not limited to the present embodiment.

In another embodiment, the IP directly assigned to the communication terminal 110 may be a global IP. In this case, the NAT processing in S312, S314, S322, S324, S332, and S334 is omitted. Also, in S342, the sender of the redirected transmission request is represented by the global IP assigned to the communication terminal 110. In S360, the data communication control server 102 refers to a database that stores global IPs and terminal IDs in association with each other, and obtains the terminal ID of the communication terminal 110 associated with the global IP of the communication terminal 110 that sent the above transmission request.

Figure 4 shows an example of the internal configuration of the data communication control server 102. In this embodiment, the data communication control server 102 includes a reverse proxy server 420 and a control server 440. In this embodiment, the control server 440 includes a DHCP control unit 442, a NAT control unit 444, a communication control unit 446, and an access analysis unit 450.

In this embodiment, the reverse proxy server 420 relays communications between the data communication control server 102 and an external information processing device. Details of the reverse proxy server 420 will be described later.

In this embodiment, the control server 440 controls data communication. The control server 440 may control various settings related to data communication.

In this embodiment, the DHCP control unit 442 assigns configuration information required for communication to a device newly connected to an IP network in accordance with the communication protocol defined in DHCP (Dynamic Host Configuration Protocol). For example, the DHCP control unit 442 assigns a local IP address to each of one or more communication terminals 110.

The DHCP control unit 442 may store in the access record server 103 the terminal ID of each of the one or more communication terminals 110 in association with the local IP address assigned to each of the one or more communication terminals 110. The DHCP control unit 442 may store in the access record server 103 the terminal ID of each of the one or more communication terminals 110 in association with the local IP address assigned to each of the one or more communication terminals 110, and information indicating when each local IP was assigned to each terminal (sometimes referred to as assignment time information).

In this embodiment, the NAT control unit 444 associates a local IP used to identify the communication terminal 110 in the mobile communication network 12 with one of the global IPs assigned to the data communication control server 102. The NAT control unit 444 may store information indicating the correspondence between the local IP and the global IP in the access record server 103. The NAT control unit 444 automatically converts the above local IP and global IP and relays the data transmission.

In this embodiment, the communication control unit 446 controls data communication for each of the one or more communication terminals 110. The method for controlling data communication is realized by a known method.

In this embodiment, the access analysis unit 450 detects that the communication terminal 110 has accessed the content distribution server 120 and received content. The access analysis unit 450 generates the above-mentioned access log and stores it in the access record server 103. The access analysis unit 450 analyzes the access log and determines at least one access pattern of one or more communication terminals 110. The access analysis unit 450 also analyzes the access log and estimates the lifestyle pattern of at least one user of one or more communication terminals 110. Details of the access analysis unit 450 will be described later.

The access record server 103 may be an example of a second storage device. The control server 440 may be an example of an information acquisition device. The DHCP control unit 442 may be an example of an address allocation unit. The access analysis unit 450 may be an example of an information acquisition device.

(An example of another embodiment)
In the present embodiment, the details of the control server 440 have been described by taking as an example a case in which the control server 440 includes a DHCP control unit 442 and a NAT control unit 444. However, the control server 440 is not limited to this embodiment. In other embodiments, the control server 440 may not include the DHCP control unit 442 and the NAT control unit 444. For example, when the IP directly assigned to the communication terminal 110 is a global IP, the control server 440 does not include the DHCP control unit 442 and the NAT control unit 444.

Figure 5 shows an example of the internal configuration of the reverse proxy server 420. In this embodiment, the reverse proxy server 420 includes an access information acquisition unit 522 and an access information transfer unit 524.

In this embodiment, the access information acquisition unit 522 acquires the above-mentioned reception confirmation signal from the communication terminal 110. In this embodiment, the access information transfer unit 524 transfers the reception confirmation signal acquired by the access information acquisition unit 522 to the control server 440.

Figure 6 shows an example of the internal configuration of the access record server 103. In this embodiment, the access record server 103 includes a terminal database 620, a local IP database 640, a NAT table 660, and an access log database 680.

In this embodiment, the terminal database 620 stores various information related to each of the one or more communication terminals 110. For example, the terminal database 620 stores a terminal ID, subscriber identification information, and subscriber information for each of the one or more communication terminals 110 in association with each other. The terminal database 620 may also store a terminal ID and access analysis information for each of the one or more communication terminals 110 in association with each other.

The subscriber identification information is information for identifying a user of the communication terminal 110 that uses the mobile communication network 12. Examples of the subscriber identification information include the name of the user and identification information assigned to the user by the communication carrier. The subscriber information is various information related to the user of the communication terminal 110. Examples of the subscriber information include gender and age. The access analysis information is information that indicates the analysis results by the access analysis unit 450.

In this embodiment, the local IP database 640 stores the local IP assigned by the DHCP control unit 442 and the terminal ID in association with each other for each of the one or more communication terminals 110. The local IP database 640 may also store the local IP assigned by the DHCP control unit 442 and the terminal ID in association with the above-mentioned assignment time information for each of the one or more communication terminals 110.

In this embodiment, the NAT table 660 stores, for each piece of information communicated between the communication terminal 110 and an information processing device external to the mobile communication network 12, information indicating the sender and information indicating the destination in association with each other. The information indicating the sender is stored in association with information before conversion in the NAT control unit 444 and information after conversion in the NAT control unit 444. The information indicating the destination is stored in association with information before conversion in the NAT control unit 444 and information after conversion in the NAT control unit 444.

In this embodiment, the access log database 680 stores, for each acknowledgement signal received by the data communication control server 102, the terminal ID of the communication terminal 110 that transmitted the acknowledgement signal and information indicating the time at which the acknowledgement signal was received (sometimes referred to as time information), in association with each other. The access log database 680 may also store, for each acknowledgement signal received by the data communication control server 102, the terminal ID of the communication terminal 110 that transmitted the acknowledgement signal, the time information, and information for identifying the content received by the communication terminal 110 (sometimes referred to as content identification information), in association with each other.

The local IP database 640 may be an example of a second storage device.

(An example of another embodiment)
In this embodiment, the details of the access record server 103 are described by taking as an example a case where the access record server 103 includes a local IP database 640 and a NAT table 660. However, the access record server 103 is not limited to this embodiment. In other embodiments, the access record server 103 may not include the local IP database 640 and the NAT table 660. For example, when the IP directly assigned to the communication terminal 110 is a global IP, the access record server 103 includes a global IP database that stores, in place of the local IP database 640, the global IP assigned to each communication terminal and the terminal ID for each of one or more communication terminals 110 in association with each other. In this case, the access record server 103 may not include the NAT table 660.

Figure 7 shows an example of the internal configuration of the access analysis unit 450. In this embodiment, the access analysis unit 450 includes an access information acquisition unit 720, an access pattern determination unit 742, a life pattern estimation unit 744, a judgment criterion determination unit 746, an extraction request reception unit 762, an extraction condition determination unit 764, and a terminal extraction unit 766. In this embodiment, the access information acquisition unit 720 includes an IP address acquisition unit 722, a terminal identification information acquisition unit 724, a time information acquisition unit 726, and a log information generation unit 728.

In this embodiment, the access information acquisition unit 720 acquires a receipt confirmation signal transmitted by the communication terminal 110 to the data communication control server 102. As described above, the receipt confirmation signal indicates that the communication terminal 110, which requested content or an advertisement from the content distribution server 120 or the advertisement distribution system 130, has received the content or advertisement. In this embodiment, the access information acquisition unit 720 generates the access log described above.

In this embodiment, the IP address acquisition unit 722 acquires, from the reverse proxy server 420, the receipt confirmation signal transmitted by the communication terminal 110 to the data communication control server 102. As described above, the receipt confirmation signal may be a signal redirected from the communication terminal 110 to the data communication control server 102 in accordance with a redirect notification transmitted from the access detection server 104 to the communication terminal 110. The content of the receipt confirmation signal may be the same as the content of the receipt confirmation signal received by the access detection server 104 from the communication terminal 110, or may be different from the content of the receipt confirmation signal.

The IP address acquisition unit 722 acquires information on the sender of the above-mentioned reception confirmation signal. As described above, in data communication between the communication terminal 110 and the data communication control server 102, the local IP assigned to the communication terminal 110 by the data communication control server 102 is used as the sender of various information transmitted from the communication terminal 110 to the data communication control server 102. This allows the IP address acquisition unit 722 to acquire the local IP address of the communication terminal 110 that transmitted the above-mentioned reception confirmation signal.

In this embodiment, the terminal identification information acquisition unit 724 refers to the local IP database 640 to acquire the terminal ID of the communication terminal 110 to which the local IP address acquired by the IP address acquisition unit 722 in relation to the above-mentioned reception confirmation signal is assigned. For example, the terminal identification information acquisition unit 724 executes a search process using the local IP acquired by the IP address acquisition unit 722 as a key. The terminal identification information acquisition unit 724 extracts a record that matches the local IP acquired by the IP address acquisition unit 722 from one or more records stored in the local IP database 640. The terminal identification information acquisition unit 724 outputs the terminal ID associated with the above-mentioned local IP in the extracted record as a search result.

In this embodiment, the time information acquisition unit 726 acquires time information indicating the time when the above-mentioned reception confirmation signal was acquired. In one embodiment, the time information acquisition unit 726 acquires information indicating the time when the data communication control server 102 received the reception confirmation signal. The time information acquisition unit 726 acquires the above-mentioned time information, for example, by using a function for acquiring the current time of the data communication control server 102.

In another embodiment, the time information acquisition unit 726 acquires time information indicating the time when the access detection server 104 received the receipt confirmation signal. For example, the access detection server 104 may use a redirect command to instruct the communication terminal 110 to transmit the above-mentioned time information to the data communication control server 102 together with the receipt confirmation signal. In yet another embodiment, the time information acquisition unit 726 acquires time information indicating the time when the communication terminal 110 actually acquired the content. For example, the access detection server 104 may use a redirect command to instruct the communication terminal 110 to transmit the above-mentioned time information to the data communication control server 102 together with the receipt confirmation signal.

In this embodiment, the log information generating unit 728 generates log information by associating the terminal ID acquired by the terminal identification information acquiring unit 724 with the time information acquired by the time information acquiring unit 726. The log information generating unit 728 may generate log information by associating the terminal ID acquired by the terminal identification information acquiring unit 724 with the time information acquired by the time information acquiring unit 726 and the content identification information described above. For example, the access detection server 104 may use a redirect command to instruct the communication terminal 110 to transmit the content identification information to the data communication control server 102 together with a reception confirmation signal. The log information generating unit 728 stores the generated log information in, for example, the access log database 680.

In this embodiment, the access pattern determination unit 742 determines the access pattern of a specific communication terminal 110 based on multiple pieces of log information related to the specific communication terminal 110 generated during a specific period. The access pattern may be (i) information indicating when the specific communication terminal 110 accesses any one or more content distribution servers 120, or (ii) information indicating when the specific communication terminal 110 accesses one or more specific content distribution servers 120.

Multiple pieces of log information relating to a specific communication terminal 110 indicate multiple times at which the specific communication terminal 110 accessed the content distribution server 120. For example, the access pattern determination unit 742 extracts log information for each period that meets a specific condition, and generates a frequency distribution for each period by totaling the number of pieces of log information for each period. The access pattern determination unit 742 generates an access pattern based on the frequency distribution. The access pattern determination unit 742 may output the frequency distribution as the access pattern.

In one embodiment, the access pattern determination unit 742 extracts log information for each day of the week, and totals the number of pieces of log information for each day of the week. In another embodiment, the access pattern determination unit 742 extracts log information for each attribute of the day of the week, and totals the number of pieces of log information for each attribute of the day of the week. Examples of attributes of the day of the week include weekday, holiday, first half of the week, and second half of the week. In another embodiment, the access pattern determination unit 742 extracts log information for each time period, and totals the number of pieces of log information for each time period. In yet another embodiment, the access pattern determination unit 742 extracts log information for each combination of the above-mentioned day of the week or attribute of the day of the week and time period, and totals the number of pieces of log information for each combination.

In this embodiment, the lifestyle pattern estimation unit 744 estimates the lifestyle patterns of each user of one or more communication terminals 110 based on the access patterns of each of the one or more communication terminals 110. The lifestyle pattern estimation unit 744 may estimate the lifestyle patterns without using machine learning, or may estimate the lifestyle patterns using machine learning.

In one embodiment, the lifestyle pattern estimation unit 744 first acquires information indicating a criterion for matching one or more lifestyle patterns from the judgment criterion determination unit 746 or the access record server 103. The judgment criterion may include one or more conditions related to at least a portion of the access pattern.

Examples of the above-mentioned criteria include that the access frequency during the weekday commuting hours and homecoming hours exceeds a first threshold, the access frequency during the weekday night exceeds a second threshold, and the access frequency during the weekday late night to early morning hours does not meet a third threshold. The above-mentioned criteria may be a criterion related to a lifestyle pattern in which a fixed internet line is not subscribed to at home. The start and end times of the above-mentioned commuting hours, homecoming hours, night, and/or late night to early morning hours may be preset. Specifically, for example, the commuting hours are set to 7:00 a.m. to 9:00 a.m.

Next, the lifestyle pattern estimation unit 744 judges whether the access pattern of the communication terminal 110 to be judged satisfies a judgment criterion for at least one of the one or more lifestyle patterns. As a result, the lifestyle pattern estimation unit 744 can determine the lifestyle pattern of each user of the one or more communication terminals 110 based on whether the access pattern satisfies a predetermined judgment criterion.

This allows the lifestyle pattern estimation unit 744 to estimate lifestyle patterns without using machine learning. As described below, the above criteria may be determined using machine learning.

In this embodiment, the criterion determination unit 746 determines the above criterion. In one embodiment, the criterion determination unit 746 determines the above criterion by, for example, acquiring information indicating the criterion determined by the operator or user of the access analysis system 100. In another embodiment, the criterion determination unit 746 determines the above criterion using machine learning. Details of the method of generating the criterion using machine learning will be described later.

In this embodiment, the extraction request receiving unit 762 receives a request to extract a communication terminal 110 exhibiting a specific access pattern or a communication terminal 110 of a user exhibiting a specific lifestyle pattern from one or more communication terminals 110. The extraction request receiving unit 762 receives the above request from, for example, the advertisement delivery system 130. This allows the advertisement delivery system 130 to deliver advertisements that match the access pattern of the communication terminal 110 and the lifestyle pattern of the user of the communication terminal 110.

In this embodiment, the extraction condition determination unit 764 determines extraction conditions that match the request accepted by the extraction request acceptance unit 762. In this embodiment, the terminal extraction unit 766 outputs the terminal IDs of one or more communication terminals 110 that match the extraction conditions determined by the extraction condition determination unit 764, among the one or more communication terminals 110 whose access analysis information is stored in the terminal database 620. The terminal extraction unit 766 transmits the output result to the sender of the above request.

As a result, for example, a user of the communication terminal 110 can receive advertisements that are useful to the user during the time period when the user is using the communication terminal 110 to view web pages, SNS pages, videos, etc. For example, a user who does not have a fixed Internet line contract can receive advertisements related to fixed Internet lines.

The access information acquisition unit 720 may be an example of an information acquisition device. The IP address acquisition unit 722 may be an example of an IP acquisition unit. The judgment criteria determination unit 746 may be an example of a criteria determination unit.

(An example of another embodiment)
In this embodiment, the details of the access analysis unit 450 have been described by taking as an example a case where a local IP assigned to the communication terminal 110 by the data communication control server 102 is used as the source of various information transmitted from the communication terminal 110 to the data communication control server 102. However, the access analysis unit 450 is not limited to this embodiment.

In another embodiment, the global IP assigned to the communication terminal 110 may be used as the source of various information transmitted from the communication terminal 110 to the data communication control server 102. In this case, the IP address acquisition unit 722 acquires the global IP address of the communication terminal 110 that transmitted the above-mentioned reception confirmation signal. In addition, the terminal identification information acquisition unit 724 refers to the above-mentioned global IP database and acquires the terminal ID of the communication terminal 110 to which the global IP address acquired by the IP address acquisition unit 722 in relation to the above-mentioned reception confirmation signal is assigned.

Figure 8 shows an example of the internal configuration of the criterion determination unit 746. In this embodiment, the criterion determination unit 746 includes a clustering unit 824, a group identification unit 826, and a criterion generation unit 828.

In this embodiment, the clustering unit 824 clusters one or more communication terminals 110 based on the access patterns of each of the one or more communication terminals 110 by unsupervised machine learning. Any known method may be adopted as the clustering algorithm. Examples of the above algorithm include a density-based clustering method such as DBSCAN, a hierarchical method such as a shortest distance method, and a non-hierarchical method such as the k-means method.

In this embodiment, the group identification unit 826 determines the lifestyle patterns of users of the communication terminals 110 included in at least one of the multiple classifications clustered by the clustering unit 824. The group identification unit 826 may determine the lifestyle patterns of users of the communication terminals 110 included in at least one of the multiple classifications clustered by the clustering unit 824 based on the access patterns of the communication terminals 110 included in the classification.

Among the multiple classifications clustered by the clustering unit 824, the lifestyle patterns of users of communication terminals 110 included in a classification that matches a predetermined condition may be determined. Examples of the predetermined condition include a condition regarding the number of communication terminals 110 included in each classification, and a condition regarding the access pattern of the communication terminals 110 included in each classification.

In one embodiment, the group identification unit 826 determines the lifestyle pattern of the user of the communication terminal 110 to be included in at least one of the above categories based on whether or not the lifestyle pattern matches a rule previously determined for each lifestyle pattern. In another embodiment, the group identification unit 826 determines the lifestyle pattern of the user of the communication terminal 110 to be included in at least one of the above categories based on a decision by the operator or user of the access analysis system 100.

For example, based on the hypothesis that a communication terminal 110 with low access frequency during a time period when many users are likely to be at home is likely to be a communication terminal 110 of a user who has not yet subscribed to a fixed Internet line, data on the access patterns during the above-mentioned time period for one or more communication terminals 110 is input to the clustering unit 824. Considering the current fixed Internet line subscription rate in Japan, among the multiple classifications clustered by the clustering unit 824, a classification containing a small number of communication terminals 110 is likely to be a classification related to communication terminals 110 of a user who has not yet subscribed to a fixed Internet line.

The group identification unit 826 compares the number of communication terminals 110 included in each classification, or the ratio of the number of communication terminals 110 included in each classification to the total number of communication terminals 110, and estimates the classification in which the number or ratio meets a specific condition as a classification related to communication terminals 110 of users who do not have a fixed Internet line contract. In this way, the group identification unit 826 can determine the lifestyle patterns of users of communication terminals 110 included in a specific classification.

In this embodiment, the judgment criterion generating unit 828 determines the above judgment criterion based on the access patterns of one or more communication terminals 110 included in the classification in which the group identifying unit 826 has identified the lifestyle pattern. The judgment criterion generating unit 828 determines, for example, a threshold value that serves as the judgment criterion for each of one or more predetermined judgment elements.

The criterion generating unit 828 may determine the above threshold value based on the decision of the operator or user of the access analysis system 100. The criterion generating unit 828 may determine the above threshold value by machine learning using the access patterns of one or more communication terminals 110 included in the classification in which the group identifying unit 826 has identified the lifestyle patterns as training data.

Figure 9 shows an example of the internal configuration of the estimation model generation unit 946. In this embodiment, the estimation model generation unit 946 generates an estimation model that is used when the lifestyle pattern estimation unit 744 estimates a lifestyle pattern by machine learning. In this embodiment, the estimation model generation unit 946 includes a teacher data acquisition unit 922 and a machine learning unit 924.

According to the embodiment described in relation to FIG. 7 and FIG. 8, the lifestyle pattern estimation unit 744 has been described in detail by taking as an example a case in which the lifestyle pattern estimation unit 744 determines or estimates the lifestyle pattern of the user of the communication terminal 110 to be judged based on a predetermined judgment criterion. However, the lifestyle pattern estimation unit 744 is not limited to the above embodiment. In the embodiment described in relation to FIG. 9, the lifestyle pattern estimation unit 744 estimates the lifestyle pattern by machine learning.

In this embodiment, the teacher data acquisition unit 922 generates teacher data for generating the above estimation model. For example, the teacher data acquisition unit 922 uses the mechanism of the advertisement distribution system 130 to conduct a web questionnaire regarding lifestyle patterns. The teacher data acquisition unit 922 stores the responses to the above web questionnaire in association with the terminal ID of the communication terminal 110 that sent the responses. The terminal ID of the communication terminal 110 that sent the responses is acquired, for example, by a method similar to that of the terminal ID of the communication terminal 110 that sent the reception confirmation signal. For example, the teacher data acquisition unit 922 refers to the terminal database 620 and generates teacher data for each of one or more communication terminals 110 by associating the responses to the above web questionnaire with the access pattern of the communication terminal 110 that sent the responses.

In this embodiment, the machine learning unit 924 generates an estimation model through machine learning using the teacher data generated by the teacher data acquisition unit 922. The machine learning unit 924 generates an estimation model through machine learning for estimating the lifestyle pattern of the user of the communication terminal 110 from the access pattern of the communication terminal 110, for example. As a result, the lifestyle pattern estimation unit 744 can output the lifestyle pattern of the user of the communication terminal 110 to be judged from the access pattern of the communication terminal 110 to be judged, using the estimation model generated through machine learning for estimating the lifestyle pattern of the user of the communication terminal 110 from the access pattern of the communication terminal 110.

Figure 10 shows an example of the internal configuration of the access detection server 104. In this embodiment, the access detection server 104 includes an access detection unit 1020, a redirect notification unit 1040, and a storage unit 1060. In this embodiment, the redirect notification unit 1040 includes a global IP acquisition unit 1042, an address acquisition unit 1044, and a command transmission unit 1046. In this embodiment, the storage unit 1060 includes a global IP database 1070 and a telecommunications carrier database 1080.

In this embodiment, the global IP database 1070 stores, for each of one or more global IPs, a global IP address 1072 in association with a telecommunications carrier identification information 1074 for identifying the telecommunications carrier to which the global IP has been assigned. The telecommunications carrier database 1080 stores, for each of one or more telecommunications carriers, a telecommunications carrier identification information 1082 in association with a receiving address 1084 indicating the destination of the receipt confirmation signal at each telecommunications carrier.

In this embodiment, the access detection unit 1020 receives a receipt confirmation signal from the communication terminal 110. The access detection unit 1020 acquires, for example, a receipt confirmation signal transmitted by the communication terminal 110 to the access detection server 104. As a result, the access detection unit 1020 detects that the communication terminal 110 has accessed the content distribution server 120 or the advertisement distribution system 130. More specifically, the access detection unit 1020 detects that the communication terminal 110 that requested content or an advertisement has received the content or advertisement.

In this embodiment, in response to the access detection unit 1020 receiving an acknowledgment signal from the communication terminal 110, the redirect notification unit 1040 transmits the above-mentioned redirect notification to the communication terminal 110 that transmitted the acknowledgment signal. The redirect notification includes an instruction to redirect the information transmitted from the access detection server 104 to the communication terminal 110 to the data communication control server 102. The information transmitted from the access detection server 104 to the communication terminal 110 may include the acknowledgment signal transmitted from the communication terminal 110 to the access detection server 104, may include information included in the acknowledgment signal transmitted from the communication terminal 110 to the access detection server 104, or may include information indicating that the access detection server 104 has received the acknowledgment signal.

In this embodiment, the global IP acquisition unit 1042 acquires the above-mentioned reception confirmation signal. The global IP acquisition unit 1042 also acquires information on the sender of the above-mentioned reception confirmation signal. As described above, in data communication between the communication terminal 110 and the data communication control server 102, the global IP converted by the data communication control server 102 is used as the sender of various information sent from the communication terminal 110 to the data communication control server 102. This allows the global IP acquisition unit 1042 to acquire the global IP address of the communication terminal 110 that sent the above-mentioned reception confirmation signal.

In this embodiment, the address acquisition unit 1044 identifies the telecommunications carrier to which the global IP address acquired in association with the receipt confirmation signal has been assigned. In this embodiment, the address acquisition unit 1044, for example, refers to the storage unit 1060 to acquire the receiving address of the telecommunications carrier to which the global IP address acquired by the global IP acquisition unit 1042 in association with the receipt confirmation signal has been assigned. This makes it possible to identify the telecommunications carrier to which the above-mentioned global IP address has been assigned.

In this embodiment, the command transmission unit 1046 generates the above redirect notification. The command transmission unit 1046 generates a command to cause the communication terminal 110 that transmitted the reception confirmation signal to execute a redirect to the receiving address acquired by the address acquisition unit 1044. The command transmission unit 1046 generates a redirect notification that includes the above command. The command transmission unit 1046 transmits the generated redirect notification to the communication terminal 110 that transmitted the reception confirmation signal.

The redirect notification unit 1040 may be an example of an information processing device. The global IP acquisition unit 1042 may be an example of a global IP acquisition unit and/or an IP acquisition unit. The address acquisition unit 1044 may be an example of a telecommunications carrier identification unit. The storage unit 1060 may be an example of a first storage device. The telecommunications carrier's receiving address may be an example of a telecommunications carrier's address.

(An example of another embodiment)
In the present embodiment, the details of the process of identifying a telecommunications carrier in the access detection server 104 have been described by taking as an example a case in which the address acquisition unit 1044 acquires the receiving address of a telecommunications carrier to which a global IP address acquired in relation to a receipt confirmation signal is assigned, thereby identifying the telecommunications carrier. However, the process of identifying a telecommunications carrier is not limited to the present embodiment.

In another embodiment, for example, the address acquisition unit 1044 refers to a database (not shown) that stores (i) one or more global IP addresses and (ii) information for identifying the telecommunications carrier to which each global IP address is assigned, in association with each other, to acquire information for identifying the telecommunications carrier to which the global IP address acquired by the global IP acquisition unit 1042 in association with the receipt confirmation signal. The address acquisition unit 1044 may acquire the address of the telecommunications carrier to which the global IP address is assigned, in association with a database (not shown) that stores information for identifying each of the one or more telecommunications carriers and the addresses of each telecommunications carrier.

Figure 11 shows a schematic diagram of another example of information processing in the access analysis system 100. In the embodiment described in relation to Figure 2, the details of information processing in the access analysis system 100 were described using as an example a case where the web page 20 includes the content body 22 and the advertisement space 24, the advertisement space 24 includes the advertisement tag 26, and the advertisement 30 includes the advertisement body 32 and the beacon tag 34. In this embodiment, another example of information processing in the access analysis system 100 is described using as an example a case where the web page 20 includes the content body 22, the advertisement space 24, and the beacon tag 34, the advertisement space 24 includes the advertisement tag 26, and the advertisement 30 includes the advertisement body 32.

The information processing according to this embodiment differs from the information processing described in relation to FIG. 2 in that in S203, when the web page 20 is executed and an impression of the advertisement occurs, S1110 similar to S210 and 1111 similar to S211 are executed. Except for the above differences and the changes based on the differences, the information processing according to this embodiment may have the same configuration as the information processing described in relation to FIG. 2.

According to this embodiment, when the web page 20 is executed in S1110, the beacon tag 34 is also executed. As a result, the browser of the communication terminal 110 transmits a request to transmit a beacon image to the access detection server 104. In addition, in S1111, the access detection server 104 transmits a beacon image and a redirect notification (not shown) to the communication terminal 110.

Figure 12 shows a schematic diagram of another example of information processing in the access analysis system 100. In this embodiment, another example of information processing in the access analysis system 100 is described using as an example a case where the Web page 20 includes the content body 22 and the beacon tag 34, but does not include the advertisement tag 26. In the information processing according to this embodiment, after S202 described in relation to Figure 2 is executed, in S1210, the browser of the communication terminal 110 executes the Web page 20 and the beacon tag 34. As a result, the browser of the communication terminal 110 transmits a request to transmit a beacon image to the access detection server 104. In addition, in S1211, the access detection server 104 transmits a beacon image and a redirect notification (not shown) to the communication terminal 110.

The CPU 3012 operates according to the programs stored in the ROM 3030 and the RAM 3014, thereby controlling each unit. The GPU 3016 acquires image data generated by the CPU 3012 into a frame buffer or the like provided in the RAM 3014 or into itself, and causes the image data to be displayed on the display device 3018.

The communication interface 3022 communicates with other electronic devices via a network. The hard disk drive 3024 stores programs and data used by the CPU 3012 in the computer 3000.

The programs are read from the computer-readable storage medium, installed in the hard disk drive 3024, RAM 3014, or ROM 3030, which are also examples of computer-readable storage media, and executed by the CPU 3012. The information processing described in these programs is read by the computer 3000, and brings about cooperation between the programs and the various types of hardware resources described above. An apparatus or method may be constructed by realizing the operation or processing of information according to the use of the computer 3000.

For example, when communication is performed between computer 3000 and an external device, CPU 3012 may execute a communication program loaded into RAM 3014 and instruct communication interface 3022 to perform communication processing based on the processing described in the communication program.

The CPU 3012 may also cause all or a necessary portion of a file or database stored on an external recording medium such as the hard disk drive 3024, the DVD-ROM drive 3026 (DVD-ROM 3001), an IC card, etc. to be read into the RAM 3014, and perform various types of processing on the data on the RAM 3014. The CPU 3012 may then write back the processed data to the external recording medium.

Various types of information, such as various types of programs, data, tables, and databases, may be stored on the recording medium and may undergo information processing. The CPU 3012 may execute various types of processing on the data read from the RAM 3014, including various types of operations, information processing, conditional judgment, conditional branching, unconditional branching, information search/replacement, etc., as described throughout this disclosure and specified by the instruction sequence of the program, and write back the results to the RAM 3014. The CPU 3012 may also search for information in a file, database, etc. in the recording medium. For example, when a plurality of entries each having an attribute value of a first attribute associated with an attribute value of a second attribute are stored in the recording medium, the CPU 3012 may search for an entry whose attribute value of the first attribute matches a specified condition from among the plurality of entries, read the attribute value of the second attribute stored in the entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition.

The above-described program or software module may be stored in a computer-readable storage medium on the computer 3000 or in the vicinity of the computer 3000. In addition, a recording medium such as a hard disk or RAM provided in a server system connected to a dedicated communication network or the Internet can be used as a computer-readable storage medium, thereby providing the above-described program to the computer 3000 via the network.
