Description

The present invention relates to a vacant house determination system, a vacant house determination method, and a vacant house determination program.

Recently, with the spread of the Internet and terminal devices such as smartphones, the number of transactions at online stores has increased dramatically. In such transactions on the Internet, products are delivered to a delivery address designated by the purchaser, and an invoice and other documents are also sent to the delivery address.

However, in transactions at these online stores, there have been many cases of fraud in which purchasers use vacant houses with no actual tenants as the delivery address and, even after receiving the delivered goods, do not pay the invoices, etc.

Such fraudulent use of vacant house addresses is not only for purchasing goods at online stores, but also for online auctions, opening bank accounts, applying for various loans and financing, exchanging points for goods, etc. Even when there is no delivery of goods, fraud is also committed by specifying vacant houses as addresses for identity verification for financial institutions and credit cards.

In order to prevent damage from such fraud, the technology disclosed in Patent Document 1 determines that the address specified as the delivery destination is fraudulent use when the address of the real estate property listed in the advertisement matches the address specified as the delivery destination of the product. Also, the technology described in Patent Document 1 compares the period listed in the advertisement with the period used as the delivery destination, and determines that the address specified as the delivery destination is fraudulent use when the periods overlap.

Furthermore, Patent Literature 2 discloses a technology that accumulates power usage status information showing the time series of power usage status in the home of an electric power service user in a storage unit, and determines whether the user is at home or not based on a comparison between the current power usage status and the past power usage status. Using this information on whether the user is at home or not, delivery companies and the like can efficiently carry out delivery work.

In the technology disclosed in Patent Document 1, fraud is determined based on the address of the real estate property listed in the advertisement, so real-time information on the real estate property listed in the advertisement is required. However, advertising information (listing information) of real estate properties is not usually linked to rental or sales information and is not controlled in real time. Usually, there is a time lag of about one to two weeks. Therefore, during this time lag, there is a possibility that the address of the vacant house will be fraudulently used by a fraudulent client.

Furthermore, the technology described in Patent Document 2 is not intended to determine whether an address entered by a user is a vacant house. Even if the technology described in Patent Document 2 were used to determine whether a house is vacant, the technology described in Patent Document 2 determines whether the user is at home or not by comparing current and past power usage conditions, so even if the house is vacant, if the current power usage conditions and past power usage conditions are similar, it will be determined that the user is at home (i.e., the house is not vacant). Also, in cases such as immediately after moving,
Because electricity usage may be low, a home may be deemed to be unoccupied (i.e., vacant) even when it is not.

Therefore, the present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a vacant house determination system, a vacant house determination method, and a vacant house determination program that can accurately and in real time determine whether an inputted address is a vacant house or not.

(1) A first aspect of the present invention relates to a vacant house determination system including a memory unit that stores a database in which multiple addresses and information on the availability of lifelines are associated and recorded; a reception unit that receives from a terminal device a request to determine whether an address is a vacant house or not; a determination unit that determines whether the address included in the received determination request is a vacant house or not by referring to the database stored in the memory unit; and a transmission unit that transmits the determination result determined by the determination unit to the terminal device.

(2) In (1) above, the database stored in the memory unit may store either only addresses to which lifelines are provided, or a list of addresses to which lifelines are not provided.

(3) In the above (1) or (2), the memory unit may further store historical information on the supply of the lifeline in the database, and the determination unit may determine the accuracy of the determination result determined by comparing the usage status of the lifeline in a most recent first specified period with the usage status of the lifeline in a second specified period prior to the first specified period.

(4) In the above (3), the judgment unit may compare the usage of the lifeline during a first specified period with the usage of the lifeline during a second specified period, and if there is a difference of a specified degree or more, judge that the accuracy of the judgment result determined by the judgment unit is low.

(5) In the above (4), the judgment unit may judge that the smaller the specified degree is, the higher the accuracy of the judgment result judged by the judgment unit, and that the larger the specified degree is, the lower the accuracy of the judgment result judged by the judgment unit.

(6) In the above (1) or (2), the memory unit may further store historical information on the supply of the lifeline in the database, and the judgment unit may judge the validity of the judgment result determined by the judgment unit by referring to the most recent usage status of the lifeline.

(7) In (6) above, when the judgment unit determines that the address included in the received judgment request is a vacant house, if the most recent usage of a lifeline is equal to or greater than a predetermined amount, the judgment unit may determine that the determination that the address included in the received judgment request is a vacant house is inappropriate.

(8) In (6) or (7) above, when the judgment unit determines that the address included in the received judgment request is not a vacant house, if the most recent usage of a lifeline is less than a predetermined amount, the judgment unit may determine that the determination that the address included in the received judgment request is not a vacant house is not valid.

(9) In any of (1) to (8) above, information on the availability of lifelines is as follows:
It may include information on multiple addresses and whether or not a contract exists with a utility supplier.

(10) A second aspect of the present invention relates to a vacant house determination method including a storage step of storing a database in which a plurality of addresses and information on the availability of lifelines are recorded in correspondence with each other; a reception step of receiving from a terminal device a request to determine whether an address is a vacant house or not; a determination step of determining whether the address included in the received determination request is a vacant house or not by referring to the database; and a transmission step of transmitting the determination result determined in the determination step to the terminal device.

(11) A third aspect of the present invention relates to a vacant house determination program that enables a computer to perform the following functions: storing a database in which multiple addresses and information on the availability of lifelines are recorded in correspondence with each other; receiving a request from a terminal device to determine whether an address is a vacant house or not; determining whether the address included in the received determination request is a vacant house by referring to the database; and transmitting the determination result determined in the determination function to the terminal device.

According to the present invention, whether an input address is a vacant house or not can be determined based on whether or not lifelines such as electricity are supplied, so that it is possible to determine with high accuracy whether an address is a vacant house or not.
In other words, the present invention determines whether a house is vacant or not based on whether or not an application for or contract for a lifeline has been made, and therefore makes it possible to provide a vacant house determination system, a vacant house determination method, and a vacant house determination program that can determine whether an address is vacant or not in real time regardless of the usage status of the lifeline.

Hereinafter, a vacant house determination system, a vacant house determination method, and a vacant house determination program according to one aspect of the present disclosure will be described with reference to the drawings. However, it should be noted that the technical scope of the present disclosure is not limited to those embodiments, but extends to the inventions described in the claims and their equivalents.

(Outline of processing by vacant house determination system 1)
FIG. 1 is a schematic diagram for explaining an example of processing by the vacant house determination system 1.

The vacant house determination system 1 includes a plurality of client terminal devices 2 and a personal information providing device 3.
The server 4 has a personal information table 411 that stores personal information received from the personal information providing device 3. The server 4 has a personal information table 411 that stores personal information received from the personal information providing device 3. The server 4 has a personal information table 411 that stores personal information received from the personal information providing device 3.
2.... is compared with the personal information stored in the personal information table 411 to determine whether the address corresponds to a vacant house.

The multiple clients are those who wish (request) to determine whether an address is vacant or not, and include Internet service providers, including EC businesses that sell goods on the Internet and businesses that hold Internet auctions, and financial institutions that require personal authentication for bank accounts and credit cards, etc. In other words, any individual or corporation that wishes to determine whether an address is vacant or not can be a client.

Furthermore, when the server 4 is a server of an Internet service provider or a financial institution, a plurality of clients become users who access the server 4. When a user wishes to obtain authentication information, the user's address is transmitted to the server of the Internet service provider or the financial institution, and the server of the Internet service provider or the financial institution determines whether the entered user's address is a vacant house or not.

The personal information providing device 3 is a business that provides a lifeline. For example, it includes an electric power company, a waterworks bureau, a gas company, a telephone company, an Internet connection company, a television broadcasting provider, a newspaper business, a regular home delivery service for beverages such as milk, and a regular door-to-door sales business for oil. In the vacant house determination system 1, at least one personal information providing device 3 only needs to receive personal information from at least one lifeline provider, and may receive personal information from multiple personal information providing devices 3. In this case, the server 4 that receives multiple personal information may merge the multiple personal information to generate the personal information table 411. Note that the personal information providing device 3 is preferably a lifeline provider such as an electric power company, a waterworks bureau, or a gas company that actually enters the house of a specific address before completing a contract or application.

The server 4 receives personal information from the personal information providing device 3, creates a personal information table 411, and stores the personal information. The server 4 may be configured to receive personal information from a plurality of personal information providing devices 3. In this case, the server 4 may create one personal information table 411 by adapting the received personal information to the same format, or may create a plurality of personal information tables 411. The server 4 stores the personal information of a plurality of client terminal devices 2, 2, 2...
The address is received from the client terminal device 2, and the address is compared with the personal information stored in the personal information table 411 to determine whether the address corresponds to a vacant house or not. The result of the determination is then transmitted to the client terminal device 2.
, 2, 2, etc.

(Overall configuration of vacant house determination system 1)
FIG. 2 is a diagram showing an example of a schematic configuration of the vacant house determination system 1.

The vacant house determination system 1 includes a plurality of client terminal devices 2, 2, 2..., a personal information providing device 3, and a server 4. Hereinafter, the plurality of client terminal devices may be simply referred to as client terminal devices 2.
and the server 4 are connected to each other via a communication network such as the Internet 5. Furthermore, the personal information providing device 3 and the server 4 are connected to each other via a communication network such as the Internet 5. Moreover, although one Internet 5 is exemplified here, if the Internet 5 is made up of a plurality of networks, a gateway (not shown) may be provided between each of the networks as appropriate.
A program executed on the client terminal device 2 (eg, a browsing program) and a program executed on the server 4 (eg, a management program) communicate with each other using a communication protocol such as the HyperText Transfer Protocol (HTTP).

Furthermore, the connection between the client terminal device 2 and the server 4, and the personal information providing device 3
The information handled in the connection between the client terminal device 2 and the server 4 is confidential, so the communication environment of the Internet 5 needs to be excellent in terms of security. In addition, security can be strengthened by providing dedicated lines for the connection between the client terminal device 2 and the server 4 and the connection between the personal information providing device 3 and the server 4.

(Schematic configuration of client terminal device 2)
FIG. 3 is a diagram showing an example of a schematic configuration of the client terminal device 2. As shown in FIG.

The client terminal device 2 executes connection to a wireless communication network, web access, etc. To that end, the client terminal device 2 includes a terminal communication unit 211, a terminal storage unit 212, a terminal operation unit 213, a terminal display unit 214, and a terminal processing unit 215.

Although a tablet PC or a notebook PC is assumed as the client terminal device 2, the present invention is not limited to this. The client terminal device 2 may be, for example, a multi-function mobile phone (a so-called "smartphone"), a mobile phone (a so-called "feature phone"), a personal digital assistant (PDA), a portable game machine, a portable music player, a tablet terminal, or the like, as long as the present invention is applicable to the client terminal device 2.

The terminal communication unit 211 includes a communication interface circuit and connects the client terminal device 2 to the Internet 5. The terminal communication unit 211 communicates with the terminal processing unit 2 via the network.
15 to the server 4 etc. The terminal communication unit 211 also supplies the terminal processing unit 215 with data received from the server 4 etc. via the network.

The device storage unit 212 includes, for example, a semiconductor memory device. The device storage unit 212 stores an operating system program, a driver program, an application program, data, and the like used in the processing by the device processing unit 215. For example, the device storage unit 21
The terminal storage unit 212 stores, as driver programs, an input device driver program for controlling the terminal operation unit 213, an output device driver program for controlling the terminal display unit 214, and the like. The terminal storage unit 212 stores, as application programs, a browsing program for displaying a registration screen for registering search conditions, feature information, feature images, and the like input by a store personnel operating the terminal operation unit 213 in the server 4, and the like. Various programs may be installed in the terminal storage unit 212 from a computer-readable portable recording medium such as a CD-ROM or DVD-ROM using a known setup program, for example. The terminal storage unit 212 may also temporarily store temporary data related to a predetermined process.

The terminal operation unit 213 may be any device capable of operating the client terminal device 2, such as a mouse, a touch panel, or key buttons. A user can use the terminal operation unit 213 to select or cancel information, and input characters, numbers, and the like. When operated by a user, the terminal operation unit 213 generates a signal corresponding to the operation. The generated signal is then transmitted to the device processing unit 215.

The terminal display unit 214 may also be any device capable of displaying video, images, etc., such as a liquid crystal display, an organic EL (Electro-Luminescence) display, etc. The terminal display unit 214 displays video corresponding to the video data supplied from the device processing unit 215, images corresponding to the image data, etc.

The device processing unit 215 includes one or more processors and their peripheral circuits. The device processing unit 215 centrally controls the overall operation of the client terminal device 2, and is, for example, a CPU. The device processing unit 215 controls the operation of the terminal communication unit 211, the terminal display unit 214, and the like so that various processes of the client terminal device 2 are executed in an appropriate order based on the programs stored in the terminal storage unit 212 and the operations of the terminal operation unit 213. The device processing unit 215 controls the operations of the programs (such as an operating system program, a driver program, and an application program) stored in the terminal storage unit 212.
In addition, the device processing unit 215 can execute a plurality of programs (such as application programs) in parallel.

The device processing unit 215 has a function of processing screen display information received from outside the client terminal device 2 as a screen display viewable by the user, and a function of converting processing based on the operation content of the terminal operation unit 213 from the user into a signal that can be transmitted outside the client terminal device 2 and sending it to the terminal transmission unit 211. These functions are functional modules realized by a program executed by a processor included in the device processing unit 215. Alternatively, each of these units may be implemented in the client terminal device 2 as an independent integrated circuit, microprocessor, or firmware.

(Processing of client terminal device 2)
The client's terminal device 2 is operated by the client. The client operates the terminal operation unit 213 to input an address for which a determination is made as to whether the house is vacant or not into the client's terminal device 2. If necessary, the terminal processing unit 215 processes or converts the address, and transmits the address to the terminal communication unit 21.
1 transmits the address to the server 4. At this time, the terminal storage unit 212 may store the address transmitted to the server 4 as history information.

Furthermore, the client's terminal device 2 may also function as the client's own system. In this case, the client's own system may automatically transmit the address to the server 4. In other words, the terminal processing unit 215 may process or convert the address obtained by the client's own system, and the terminal communication unit 212 may transmit the address to the server 4.
Alternatively, the client's terminal device 2 may be another server. In that case, the other server may transmit the address to the server 4 from information processed therein. Furthermore, the client's terminal device 2 may transmit the address together with other information to the server 4. As described above, when the client is a user who requests authentication information from a server of an Internet service provider or a financial institution, the terminal device owned by the user becomes the client's terminal device 2.

(Processing of personal information providing device 3)
The personal information providing device 3 provides personal information to the server 4 in response to a request from the server 4. The personal information providing device 3 may transmit personal information to the server 4 every time there is a request from the server 4, or the personal information providing device 3 may transmit personal information to the server 4 periodically. Furthermore, when the personal information providing device 3 also serves as the server 4, the personal information providing device 3 receives an address from the client's terminal device 2 without transmitting personal information to the server 4, and determines whether the address is a vacant house or not. Although not shown, the personal information providing device 3 may be provided with server components such as a communication unit and a storage unit.

The personal information providing device 3 may be configured to provide the latest personal information to the server 4 when the address accepted from the client terminal device 2 is not included in the personal information received by the server 4 from the personal information providing device 3, or when the accuracy of the determination result of the determination unit 414 is low based on the lifeline usage history information included in the personal information table 411, as described below. With such a configuration, the frequency of updates to the personal information in the personal information providing device 3 can be reduced, thereby limiting the amount of communication on the server 4.

The personal information provided by the personal information providing device 3 to the server 4 includes at least an address and whether or not a lifeline contract has been made. The personal information providing device 3 may not include information on whether or not a lifeline contract has been made in the personal information, and may provide only personal information for which a lifeline contract has been made to the server 4 as personal information, or may provide only personal information for which a lifeline contract has not been made to the server 4 as personal information. Note that the personal information provided by the personal information providing device 3 does not include personal information including addresses with which the lifeline provider providing the personal information providing device 3 has never made a contract in the past, and by providing only personal information including addresses with which a contract has been made to the server 4, it is possible to transmit the determination result to the client's terminal device 2 when the address received from the client's terminal device 2 cannot be determined.

(Schematic configuration of server 4)
FIG. 4 is a diagram showing an example of a schematic configuration of the server 4.

The server 4 includes a server storage unit 41 that stores a personal information table 411 that stores personal information.
The server 4 refers to the personal information table 411 in response to requests from the terminal devices 2 of the multiple clients, and determines whether the addresses received from the terminal devices 2 of the multiple clients are present in the personal information table 411. In order to realize the above-mentioned functions,
In addition to the server storage unit 412, the server 4 includes a reception unit 413, a determination unit 414, and a generation unit 415.
The server 410 further includes a server processing unit 416 including a server control unit 15, and a server communication unit 417.

The personal information table 411 assigns the personal information received by the server communication unit 417 to personal information identification information for each piece of personal information, and further stores information on whether or not a lifeline contract is made in association with each personal information identification information. Note that the personal information needs to include at least an address. Furthermore, if the personal information table 411 does not store information on whether or not a lifeline contract is made, the personal information received by the server communication unit 417 may be a list of addresses with a lifeline contract or a list of addresses without a lifeline contract.
Furthermore, instead of the lifeline contract, the presence or absence of an application for a lifeline may be stored as information stored in the personal information table 411. In the present invention, the presence or absence of a lifeline contract or the presence or absence of an application for a lifeline can correspond to the supply of a lifeline.

Although details will be described later, personal information table 411 further stores lifeline usage history information for each personal information identification information (individual address). This lifeline usage history information may be stored separately from personal information table 411 in server storage unit 412. It is sufficient that the lifeline usage history information is stored only for a predetermined period, such as the most recent few months, and the usage history information may be deleted after the predetermined period has elapsed.

The server storage unit 412 includes, for example, at least one of a semiconductor memory, a magnetic disk device, and an optical disk device, and is connected to the server 4 via a bus.
2 stores driver programs, operating system programs, application programs, data, etc., used in processing by the server processing unit 416. For example,
The server storage unit 412 stores, as a driver program, a communication device driver program for controlling the server communication unit 417. The computer program is, for example, a CD-ROM.
The software may be installed in the server storage unit 412 from a computer-readable portable recording medium such as a ROM or a DVD-ROM using a known setup program.
Furthermore, the server storage unit 412 stores the personal information table 411 etc. The server storage unit 412 can correspond to the storage unit of the present invention.

The server processing unit 416 includes a receiving unit 413 , a determining unit 414 , and a generating unit 415 .
The functions of the server processing unit 416 are functional modules realized by a program executed by a processor included in the server processing unit 416. Alternatively, each of these units may be implemented in the server 4 as an independent integrated circuit, microprocessor, or firmware. The processing content of the server processing unit 416 will be described later. Also, the division of the components of the server processing unit 416 is one example, and which components perform which processing is not limited to the description of this embodiment.

The reception unit 413 collectively receives addresses received from the terminal devices 2 of multiple clients via the server communication unit 417 described later. Specifically, the reception unit 413 receives an address from a client as a request to determine whether or not the house is vacant. In the present invention, the reception unit 413 can correspond to the reception unit. Note that the server storage unit 412 may be configured to store the address received by the reception unit 413, but from the viewpoint of protecting personal information, it is preferable to configure the server storage unit 412 not to store the received address, but to store the received address in a temporary storage area (memory) and have the server processing unit 416 perform processing to determine whether or not the house is vacant. This temporary storage area may also be managed by the server storage unit 412.

The determination unit 414 determines whether or not an address accepted by the acceptance unit 413 from multiple client terminal devices 2 is a vacant house. That is, the determination unit 414 refers to the personal information table 411 to determine whether or not a lifeline contract exists for the accepted address. If a lifeline contract exists, the determination unit 414 determines that the address accepted by the acceptance unit 413 is not a vacant house. On the other hand, if no lifeline contract exists, the determination unit 414 determines that the address accepted by the acceptance unit 413 is a vacant house.

The determination unit 414 can perform a more accurate determination based on the lifeline usage history information stored in the server storage unit 412. For example, if a lifeline contract remains but the house is already vacant due to moving, the house is determined not to be vacant even though the house is actually vacant. On the other hand, if a lifeline contract exists but the occupant has not moved in due to moving, the house is determined not to be vacant even though the house is actually vacant. In addition, if the personal information providing device 3 does not provide personal information in a timely manner, even if it is determined that the lifeline contract does not exist, the occupant may have actually moved in. Conversely, if the lifeline contract has expired but the existence or nonexistence of the lifeline contract is not checked in a timely manner, the house is determined not to be vacant.

Therefore, the determination unit 414 determines whether or not the house is vacant based on the lifeline usage history information stored in the server storage unit 412. First, the determination unit 414 obtains the usage status of the lifeline for the most recent first specified period from the server storage unit 412, and obtains the usage status of the lifeline for the second specified period prior to the most recent specified period from the server storage unit 412. The determination unit 414 then compares the usage status of the lifeline for the first specified period with the usage status of the lifeline for the second specified period, and if there is a difference of a predetermined degree or more,
It is determined that the information on whether or not a house is vacant, based on whether or not a utility contract is in place, may be incorrect.

The generation unit 415 generates various display screens to be transmitted to the client terminal device 2 .
In particular, the server 416 generates a screen including the determination result of whether the house is vacant or not, as determined by the determination unit 414, and transmits the screen to the client's terminal device 2 via the server communication unit 417.

The determination result of whether or not the house is vacant generated by the generation unit 415 may be stored in the server storage unit 412. However, from the viewpoint of protecting personal information, it is preferable to store the determination result of whether or not the house is vacant in the server storage unit 412, and to store the generated result of the generation unit 415 in a temporary storage area (memory) and transmit it to the client's terminal device 2. This temporary storage area may also be managed by the server storage unit 412.

The server communication unit 417 has a communication interface circuit for connecting the server 4 to the Internet 5. The server communication unit 417 receives an address for which a determination as to whether the house is vacant or not from the client terminal device 2, and transmits the determination result by the determination unit 414 to the client terminal device 2. The server communication unit 417 also receives information when receiving personal information from the personal information providing device 3. The server communication unit 417 performs various communications with the client terminal device 2 as necessary, and the server communication unit 417 performs various communications with the personal information providing terminal 3 as necessary.

(Personal information table data structure)
Fig. 5 is a diagram showing an example of the structure of the personal information table 411. Fig. 6 is a table showing an example of the usage history information of lifelines for each individual address.

Note that the personal information table 411 may not be stored in the server storage unit 412, but may be stored in the personal information providing device 3 or another external storage device (server). In this case, when using information stored in the personal information table, the server 4 accesses the other device that stores the personal information table 411 to acquire the information stored in the table. Also, each piece of information included in the personal information table 411 may be stored in a format other than a table, and may be stored independently, for example.

5 is a table illustrating an example of the structure of the personal information table 411. The personal information table 411 includes personal information identification information (personal information identification ID), an address, and information on whether or not a lifeline contract has been made. The personal information identification information may be assigned to each address by the server 4, or may be assigned by the personal information providing device 3. Note that if the personal information table 411 does not include information on whether or not a lifeline contract has been made and instead stores a list of whether or not a lifeline contract has been made, the personal information table 411 does not need to store information on whether or not a lifeline contract has been made.
When accepting personal information from a plurality of personal information providing devices 3, the personal information table 411 is
It is necessary to convert the list of personal information created in a plurality of different formats into the format shown in Fig. 5 and store it. In this case, there is a possibility that a plurality of personal information providing devices 3 hold the same personal information. Therefore, it is preferable to merge such duplicated personal information in the personal information table 411 as appropriate. Furthermore, if the information on the existence or nonexistence of a lifeline contract contained in the plurality of personal information providing devices 3 is not the same, the personal information data obtained from the personal information providing device with the most recent update date and time can be stored preferentially in the personal information table 411.

FIG. 6 is a table showing an example of usage history information of lifelines for each address.
Although it is assumed that the server storage unit 412 stores the usage history information, from the viewpoint of protecting personal information, the personal information providing device 3 may store the information, and the server 4 may access the personal information providing device 3 each time. As shown in Fig. 6, the usage history information of the lifeline is the usage history for each address, and therefore the usage history information is stored in association with each address or personal information identification information. Specifically, the period of use and the amount of use are stored in association with the personal information identification information.

(Processing by vacant house determination system 1)
Figure 7 is a diagram showing an example of an operational sequence of the series of steps taken by the vacant house determination system 1 in this embodiment, in response to a determination request for a specific address from a client's terminal device 2, to determine whether the address is vacant or not, and to sending the determination result to the client's terminal device.

The operation sequence described below is executed mainly by the server processing unit 416 in cooperation with each element of the server 4, based on a program previously stored in the server storage unit 412. In the operation sequence described below, the server 4 transmits and receives various information to and from the client terminal device 2 via the server communication unit 417.

First, the reception unit 413 of the server 4 receives a determination request from the client terminal device 2 requesting a determination as to whether a specific address is vacant or not (S101). The information included in the determination request is at least the address, and other information may be received at the same time. In addition, since an address must be able to identify a single residence, it must include information on the street number and building number in addition to the prefecture and city/town/village. Therefore, the reception unit 413 performs a process to determine whether the received address is complete, and the determination unit 414 determines whether the received address is complete (S102).

If the address received by the reception unit 413 is not complete (NO in S102), error information is sent from the server communication unit 417 to the client terminal device 2, and the process ends.
On the other hand, if the address received by the reception unit 413 is complete (YES in S102), the judgment unit 414 judges whether or not the address received by the reception unit 413 is included in the personal information received from the personal information providing device 3 (S103). In other words, if the address received by the reception unit 413 is an address not included in the personal information table 411 (NO in S103), the judgment unit 414 cannot judge whether or not the house is vacant, and therefore error information is sent from the server communication unit 417 to the client terminal device 2. In this case as well, the process is terminated.

If the address received by the reception unit 413 exists in the personal information table 411 (S103 is Y),
ES), the determination unit 414 searches the personal information received from the personal information providing device 3 for an address that matches the address received by the reception unit 413, and determines whether or not a lifeline contract exists for the address received by the reception unit 413 (S104).

In the example of the personal information table 411 shown in FIG. 5, it can be seen that there is no lifeline contract for the address associated with the personal information ID 0003.

When the personal information table 411 does not include information on whether or not a lifeline contract exists for each piece of personal information, and only personal information for which a lifeline contract exists is provided to the server 4 as personal information, the determination unit 414 can only determine that the house is not vacant. On the other hand, when the personal information table 411 provides the server 4 with only personal information for which a lifeline contract does not exist, the determination unit 414 can only determine that the house is vacant.

Next, the determination unit 414 compares the usage status of the lifelines in the most recent first specified period with the usage status of the lifelines in the second specified period prior to the most recent specified period, and if there is a difference of a predetermined degree or more, determines that the information on whether or not the house is vacant, which was determined based on the presence or absence of a contract for the lifelines, may be incorrect (S105).
It is possible to further perform an accuracy determination as to how accurate the result of the previous determination in S103 is. The determination unit 414 determines that the accuracy of the result of the determination in S104 is high as the difference in the predetermined degree is smaller, and determines that the accuracy of the result of the determination in S104 is low as the difference in the predetermined degree is larger.

In the example of Figure 6, the usage (power usage) of the lifeline in the most recent first specified period has decreased significantly compared to the usage information (power usage) of the lifeline in the previous second specified period, so it can be determined that there is a possibility that the person has moved to a residence including a specific address in the most recent first specified period regardless of whether or not they have a contract for the lifeline (the accuracy of the determination result of S104 is low).
On the other hand, as an example different from the example in Fig. 6, if the usage status (power usage) of the lifeline in the most recent first specified period has increased significantly compared with the usage information (power usage) of the lifeline in the previous second specified period, it can be determined that there is a possibility that the person moved into a residence including a specific address in the most recent first specified period regardless of whether or not there is a contract for the lifeline (the accuracy of the determination result in S104 is low). Also, in the example in Fig. 6, half-year usage history information is stored in personal information table 411 for each personal information identification information, and the specified period is set to one month.
By shortening this predetermined period, it is possible to perform a more accurate judgment. However, if the predetermined period is set to about one day to one week, it will be determined that the house is likely to be vacant if the occupant is absent for a long period of time, so the predetermined period is preferably about half a month.

Next, the server communication unit 417 generates a determination result to be sent to the client terminal device 2 based on the determination result obtained in S104 and the accuracy determination result of the determination result obtained in S105, and sends the determination result to the client terminal device 2 (S106). Note that the server communication unit 417 may be configured to transmit the determination result obtained in S104 based only on the presence or absence of a lifeline contract to the client terminal device 2 without performing the accuracy determination in S105.

As described above, the vacant house determination system 1 according to the present embodiment can determine whether an address included in a request from a terminal device 2 of a plurality of clients is vacant or not, depending on whether or not there is a lifeline contract, and can further determine the accuracy of the determination result based on the lifeline usage history information. In recent years, smart meters are often used depending on the type of lifeline, and it is possible to determine whether or not a house is vacant with high accuracy only from the information on whether or not there is a lifeline contract. In addition, by using the lifeline usage history information, the accuracy of the determination result of whether or not a house is vacant can be further determined, thereby further increasing the accuracy of the determination of whether or not a house is vacant.

It should be understood by those skilled in the art that various changes, substitutions and modifications can be made to the present invention without departing from the spirit and scope of the present invention. It should also be understood that the modifications described below can be combined with each other to implement the present invention.

(Variation 1)
As shown in the personal information table 411 in Fig. 5, there are many variations in the way addresses are written. When there are variations in the way addresses are written, if the address writing of the address held by the personal information providing device 3 differs from the address writing of the address received from the client terminal device 2, the determining unit 4
Therefore, in this embodiment, when the server 4 receives personal information from the personal information providing device 3, the server 4 merges the address notations included in the personal information received from the personal information providing device 3, changes the format to a unified format, and stores the address notations in the personal information table 41.
1. In addition, by inserting a process for matching the address notation of the address received from the client's terminal device 2 either before or after S102, the address notation of the address received from the client's terminal device 2 can be matched to the format of the personal information table 411, so that the determination unit 414 can normally determine whether or not the house is vacant.

Figure 8 is a diagram showing an example of an operation sequence of the series of steps in which the vacant house determination system 1 in accordance with the variant example 1 of this embodiment determines whether an address is vacant or not in response to a determination request for a specific address from a client's terminal device 2, and transmits the determination result to the client's terminal device.

For example, as shown in FIG. 8, when the address received by the reception unit 413 is complete (S10
If the answer to step S102 is YES (S103), the reception unit 413 can perform a process of matching the display of the address received (S107). When the matching of the address notation is completed, the determination unit 414 determines whether the address received by the reception unit 413 is included in the personal information received from the personal information provision device 3 (S103).

(Variation 2)
In this embodiment, the determination unit 414 determines the accuracy of the determination result of S104 by comparing the usage status of the lifeline in the most recent first predetermined period with the usage status of the lifeline in the second predetermined period prior to the most recent predetermined period, and determines whether or not there is a difference of a predetermined degree or more. However, the determination unit 414 can determine the validity of the determination result of S104 using only the most recent usage status of the lifeline.

Figure 9 is a diagram showing an example of an operation sequence of a series of steps in which the vacant house determination system 1 in accordance with the variant example 2 of this embodiment determines whether an address is vacant or not in response to a determination request for a specific address from a client's terminal device 2, and transmits the determination result to the client's terminal device.

For example, as shown in FIG. 9, after the reception unit 413 determines whether or not a lifeline contract exists for the received address in S104, the reception unit 413 refers to the most recent lifeline usage history for the address and performs S10.
The validity of the determination result of 4 is judged (S108). Specifically, when the determination unit 414 determines that the address received by the reception unit 413 is not a vacant house, if the usage of the nearest lifeline is extremely low (almost zero), the determination unit 414 judges that the determination that the address received by the reception unit 413 is not a vacant house is not valid. On the other hand, when the determination unit 414 determines that the address received by the reception unit 413 is a vacant house, if the usage of the nearest lifeline is more than a predetermined amount (not zero), the determination unit 414 judges that the determination that the address received by the reception unit 413 is a vacant house is not valid.

(Variation 3)
In this embodiment, the server 4 executes the processes from S101 to S106, but the present invention can also be implemented by having at least a part of the processes from S101 to S106 executed by the terminal devices 2 of multiple clients. In this case, the server 4 transmits an API (Application Programming Interface) to the terminal devices 2 of the clients through the server communication unit 417.
By providing the personal information table 411 and the like, the present invention can be implemented in cooperation with the server 4 and the terminal processing unit 215 of the client terminal device 2.
From the viewpoint of protecting personal information, it is difficult to send the information outside the server 4.
It is not preferable to execute the processes of S103, S104, and S105 on the client terminal device 2. Therefore, at least a part of the processes other than S103, S104, and S105 can be distributed as an API or the like. Also, if the personal information table 411 can be made available to the outside, all of the processes from S101 to S106 may be executed within the client terminal device 2.

(Variation 4)
In this embodiment, the server 4 executes the processes from S101 to S106. However, it may be difficult to provide personal information from the personal information providing device 3. In that case, the personal information table 411 is present in the personal information providing device 3.
, S104, and S105 cannot be completed within the server 4.
The processes of S101 to S106 must be performed by the personal information providing device 3. As in the third modification, the server communication unit 417 can provide the personal information providing device 3 with an API that enables the personal information providing device 3 to perform at least a part of S101 to S106. Furthermore, the personal information providing device 3 can be configured to perform all of the processes of S101 to S106.
