The following describes an embodiment of the present invention with reference to the attached drawings.

<System Configuration>
First, an overview of an information providing system 100 according to an embodiment will be described.

Figure 1 is a diagram showing an example of the system configuration of an information provision system according to an embodiment. The information provision system 100 includes, for example, an information provision device 110, one or more information terminals 120a, 120b, ... (or programs executed on the information terminals 120a, 120b, ...), an attribute management device 130, and a broadcasting device 140. In the following description, "information terminal 120" is used to refer to any one of the one or more information terminals 120a, 120b, ....

The information providing device 110 and the attribute management device 130 are connected to a network 101, such as the Internet or a LAN (Local Area Network). The information terminal 120 can connect to the network 101 using wireless communication, such as LTE (Long Term Evolution) or a wireless LAN, and can communicate with the information providing device 110, the attribute management device 130, and the like. The broadcasting device 140 can connect to the network 101 by wireless communication or wired communication, and can communicate with other devices, such as the information providing device 110.

As an example, the broadcasting device 140 is mounted on a bus, train, or the like, and uses an output device 141 such as a speaker provided inside the vehicle, such as the bus or train, to output a voice announcement using sound waves 142 including identification information (hereinafter referred to as a broadcast ID) that identifies the broadcast content into the vehicle. The broadcast ID is an example of first identification information that identifies the broadcast content.

As an example, when the broadcasting device 140 is mounted on a bus, the broadcasting device 140 broadcasts voice announcements inside the vehicle, including operation announcements such as "The next stop will be in front of XX," and advertising announcements such as "This bus stop is convenient for XX Dental Clinic for dental treatment." Furthermore, in this embodiment, these voice announcements include a broadcast ID for identifying the broadcast content. For example, the broadcast ID for identifying the voice announcement is embedded in the voice announcement as a digital watermark or the like.

However, this is not limited to the above, and the broadcast ID may be output using a frequency band (e.g., 16 kHz to 20 kHz) that is difficult for people to hear, such as 16 kHz or higher. In this case, the broadcast device 140 can output sound waves containing the broadcast ID into the vehicle at any timing, even when it is not outputting an audio announcement.

The broadcasting device 140 and the audio announcements that the broadcasting device 140 broadcasts inside vehicles such as buses and trains may be similar to the conventional technology disclosed in, for example, Patent Document 1, and therefore a detailed description thereof will be omitted here.

The information terminal 120 is a terminal device equipped with a microphone (hereinafter referred to as a mic), such as a smartphone, tablet terminal, or wearable terminal. By executing an application program (hereinafter referred to as an app) corresponding to the information provision system 100, the information terminal 120 can acquire sound waves broadcast by the broadcast device 140 using the microphone of the information terminal 120, and analyze the acquired sound waves to acquire a broadcast ID.

In addition, the information terminal 120 transmits terminal information including the acquired broadcast ID and identification information (e.g., an app ID) for identifying the information terminal 120 to the information providing device 110 via the network 101.

Furthermore, after transmitting the terminal information, the information terminal 120 displays content transmitted from the information providing device 110 that is related to the location where the broadcast content will be broadcast (e.g., the area around the next bus stop).

The app ID is identification information generated by an app when, for example, an app corresponding to the information providing system 100 is installed on the information terminal 120. By using this app ID, the information providing system 100 can identify the user and the information terminal 120 without relying on the user's personal information or the unique information of the information terminal 120.

The application ID is a suitable example of second identification information for identifying the information terminal 120. The second identification information may be, for example, identification information (device ID) unique to the information terminal 120, a telephone number, an IP address (or a MAC address), etc.

The information providing device 110 is an information processing device having a computer configuration, or a system including multiple information processing devices. The information providing device 110 manages a broadcast ID (first identification information) that identifies the broadcast content and multiple pieces of content related to the broadcast content in association with each other.

The information providing device 110 also receives terminal information sent from the information terminal 120, and uses the application ID included in the terminal information to obtain attribute information indicating the attributes of the user using the information terminal 120 from the attribute management device 130, etc.

Here, attribute information is information that indicates the hobbies, preferences, tendencies, etc. of a user, determined based on the behavioral history of the user who uses the information terminal 120 (e.g., the types of content viewed by the user, the number of times viewed, etc.). For example, attribute information can be obtained by acquiring the behavioral history of multiple users corresponding to multiple app IDs, and classifying the app IDs into multiple attributes using known cluster analysis, etc.

Furthermore, the information providing device 110 provides (transmits) different content from multiple contents related to broadcast content managed by the information providing device 110 to the information terminal 120 according to the attribute information.

The attribute management device 130 is an information processing device having a computer configuration, or a system including multiple information processing devices. The attribute management device 130 manages an application ID (second identification information) in association with the above-mentioned attribute information corresponding to the application ID. Furthermore, when the attribute management device 130 receives an acquisition request for attribute information including the application ID from the information providing device 110, it replies to the information providing device 110 with the attribute information corresponding to the application ID included in the acquisition request.

The attribute management device 130 may, for example, acquire an attribute information DB (database) that associates app IDs with attribute information corresponding to the app IDs from another information processing device, a cloud service, etc., and store and manage the information in a storage unit, etc. Alternatively, the attribute management device 130 may, for example, acquire behavioral history information of multiple users corresponding to multiple app IDs from the information providing device 110, etc., and create an attribute information DB using a known method such as cluster analysis.

With the above configuration, in FIG. 1, even if the same broadcast ID is acquired, information terminal 120a used by user A and information terminal 120b used by user B, whose attributes are different from those of user A, display different content according to the user's attributes.

As described above, according to this embodiment, the information providing system 100 that provides content corresponding to broadcast content to the user's information terminal can provide different content to various users.

The system configuration of the information providing system 100 shown in FIG. 1 is an example. For example, the functions of the attribute management device 130 may be included in the information providing device 110. Furthermore, instead of the attribute management device 130, the information providing device 110 may acquire attribute information of a user who uses the information terminal 120 from an external information processing device or a cloud service, etc.

At least some of the functions of the broadcasting device 140 may be possessed by the output device 141. Furthermore, the broadcasting device 140 and the output device 141 may be provided not only in buses or trains, but also at bus stops or train platforms. Furthermore, the broadcasting device 140 and the output device 141 may be provided in various transport vehicles, such as taxis, airplanes, and ships. Furthermore, the broadcasting device 140 and the output device 141 may be provided indoors in various facilities or outdoors in various facilities in towns, etc.

[First embodiment]
<Functional configuration>
Next, the functional configuration of the information providing system 100 according to the first embodiment will be described.

Figure 5 is a diagram showing an example of the functional configuration of the information provision system according to the first embodiment. Here, examples of the functional configuration of the information provision device 110, the information terminal 120, and the attribute management device 130 are described. Note that the broadcast device 140 and the output device 141 can be implemented using the conventional technology disclosed in, for example, Patent Document 1, and therefore description thereof is omitted here.

(Functional configuration of information providing device)
2 executes a predetermined program, the information providing device 110 realizes a communication unit 501, a content management unit 502, a terminal information receiving unit 503, an attribute information acquiring unit 504, an identifying unit 505, an information providing unit 506, a storage unit 507, etc. Note that at least a part of the above functional configurations may be realized by hardware.

The communication unit 501 connects the information providing device 110 to the network 101 and communicates with other devices, for example, using the network I/F 208 in FIG. 2.

The content management unit 502 manages a broadcast ID (first identification information) that identifies the broadcast content, in association with multiple pieces of content related to the broadcast content. For example, the content management unit 502 stores and manages content information 508 as shown in FIG. 6(A) in the storage unit 507, etc.

Fig. 6 (A) shows an example of content information 508. In the example of Fig. 6 (A), content information 508 includes information such as "broadcast content", "broadcast ID", "common content", and "individual content" as items.

"Broadcast content" is information indicating the broadcast content broadcast by broadcast device 140. For example, if broadcast device 140 is installed inside a bus, "broadcast content" stores a message such as "Next stop: in front of Hospital A" that is broadcast inside the bus. "Broadcast ID" is broadcast ID1 (first identification information) that identifies the broadcast content. "Common content" is content (e.g., web pages, images, etc.) that is commonly provided to one or more information terminals 120 that have acquired the broadcast ID.

"Individual content" is multiple pieces of content that correspond to the broadcast contents. In the example of FIG. 6(A), "individual content" stores multiple content types and content that corresponds to each content type (e.g., web pages, images, etc.).

As another example, an "individual content" may store multiple attributes and content corresponding to each attribute, as shown in FIG. 6(B).

The content information 508 is created in advance, for example, by a service provider that provides the information provision system 100, and is stored in the storage unit 507 of the information provision device 110. Preferably, the content information 508 can change information such as common content and individual content, for example, by accessing a web page provided by the content management unit 502.

In this way, the content information 508 stores a broadcast ID that identifies the broadcast content and multiple pieces of content (individual content) related to the broadcast content in association with each other. Note that, among the content information 508 shown in FIG. 6(A), information such as "broadcast content," "common content," and "type of content" are optional.

Now, returning to FIG. 5, we will continue explaining the functional configuration of the information providing device 110.

The terminal information receiving unit 503 receives terminal information including the broadcast ID (first identification information) and the app ID (second identification information) transmitted from the information terminal 120 that has acquired the broadcast ID (first identification information) via the communication unit 501.

The attribute information acquisition unit 504 acquires attribute information indicating the attributes of the user who uses the information terminal 120 that transmitted the terminal information, based on the application ID included in the terminal information received by the terminal information receiving unit 503. For example, the attribute information acquisition unit 504 transmits an acquisition request for attribute information including the application ID to the attribute management device 130, and acquires the attribute information returned from the attribute management device 130.

Based on the broadcast ID included in the terminal information and the attribute information acquired by the attribute information acquisition unit 504, the identification unit 505 identifies the content corresponding to the attribute information from among multiple contents related to the broadcast contents managed by the content management unit 502. As an example, the identification unit 505 stores and manages correspondence information 509 as shown in FIG. 6(C) in the storage unit 507 or the like.

In the example of FIG. 6(C), the correspondence information 509 stores, for each broadcast ID, multiple attributes and the type of content corresponding to each attribute in association with each other. As a result, for example, if the broadcast ID included in the terminal information is "001" and the attribute information acquired by the attribute information acquisition unit 504 indicates an attribute "A2", the identification unit 505 can identify the content type "pharmaceuticals". Furthermore, the identification unit 505 can identify "content A2" corresponding to the content type "pharmaceuticals" from among multiple individual contents corresponding to the broadcast ID "001" stored in the content information 508 as shown in FIG. 6(A).

Note that the process in which the identification unit 505 uses the correspondence information 509 to identify content that corresponds to the attribute information from among multiple pieces of content related to the broadcast content managed by the content management unit 502 is one example.

As another example, the identification unit 505 may input attribute information into a prediction model previously trained by machine learning, and identify content corresponding to the attribute information from among multiple pieces of content related to the broadcast content managed by the content management unit 502.

Here, machine learning refers to a technology that allows a computer to acquire human-like learning capabilities, in which the computer autonomously generates algorithms necessary for judgments such as data identification from training data that is previously loaded, and applies these to new data to make predictions. The learning method for machine learning may be any of supervised learning, unsupervised learning, semi-supervised learning, reinforcement learning, and deep learning, or may be a combination of these learning methods; any learning method for machine learning is acceptable.

The identification unit 505 may also identify content corresponding to the attribute information using a trained prediction model provided by a cloud service or the like.

Furthermore, as shown in FIG. 6(B), when the correspondence between attributes and content is stored in the "individual content" of the content information 508, the content is identified by the attribute information, so the information providing device 110 does not need to have an identification unit 505.

The information providing unit 506 provides (transmits) different content from among multiple contents related to the broadcast contents managed by the content management unit 502 according to the attribute information acquired by the attribute information acquisition unit 504 to the information terminal 120 that transmitted the terminal information. For example, the information providing unit 506 provides the content (individual content) identified by the identification unit 505 to the information terminal 120 that transmitted the terminal information.

Alternatively, the information providing unit 506 may obtain individual content corresponding to the broadcast ID included in the terminal information and the attribute information obtained by the attribute information obtaining unit 504 from the content information 508 as shown in FIG. 6(B), and provide the individual content to the information terminal 120 that transmitted the terminal information.

The storage unit 507 is realized, for example, by the program executed by the CPU 201 in FIG. 2, the HD 204, the HDD controller 205, the RAM 203, etc., and stores various information and data such as content information 508 and correspondence information 509.

(Functional configuration of information terminal)
3 executes a predetermined program, the information terminal 120 realizes a communication unit 521, a sound wave acquisition unit 522, a sound wave analysis unit 523, a terminal information transmission unit 524, a display control unit 525, an operation reception unit 526, a storage unit 527, etc. Note that at least a part of the above functional configurations may be realized by hardware.

The communication unit 501 connects the information terminal 120 to the network 101 using, for example, the long-distance communication circuit 311 in FIG. 3, and communicates with other devices such as the information providing device 110.

The sound wave acquisition unit 522 acquires sound waves around the information terminal 120, for example, using the microphone 314 and sound input/output I/F 316 in FIG. 3. The acquired sound waves are converted into sound wave data, for example, and stored in the storage unit 527, etc.

The sound wave analysis unit (analysis unit) 523 analyzes the sound waves acquired by the sound wave acquisition unit 522 and extracts the broadcast ID contained in the sound waves. For example, the sound wave analysis unit 523 analyzes the sound wave data stored in the storage unit 527 or the like by the sound wave acquisition unit 522, and extracts the broadcast ID if the sound waves contain the broadcast ID.

The terminal information transmission unit (transmission unit) 524 executes a transmission process to transmit terminal information including the broadcast ID (first identification information) extracted by the sound wave analysis unit 523 and the application ID (second identification information) that identifies the information terminal 120 to the information providing device 110 via the communication unit 521.

After the terminal information transmission unit 524 transmits the terminal information to the information providing device 110, the display control unit (display unit) 525 executes a display process to display the content (e.g., web pages, images, etc.) provided by the information providing device 110 on the display 317 in FIG. 3, etc.

The operation reception unit 526 receives, for example, input operations, selection operations, etc., performed by the user on the display screen displayed by the display control unit 525.

The memory unit 527 is realized, for example, by the program executed by the CPU 301 in FIG. 3, the storage device 304, the RAM 303, etc., and stores various information such as the sound wave data acquired by the sound wave acquisition unit 522.

(Attribute Management Device)
2 executes a predetermined program, the attribute management device 130 realizes a communication unit 511, an attribute information management unit 512, a storage unit 513, etc. Note that at least a part of the above-mentioned functional configurations may be realized by hardware.

The communication unit 511 connects the attribute management device 130 to the network 101 using, for example, the network I/F 208 in FIG. 2, and communicates with other devices such as the information providing device 110.

The attribute information management unit 512 associates an application ID (second identification information) with attribute information corresponding to the application ID, and stores and manages the associated information in the attribute information DB 514. Furthermore, when the attribute information management unit 512 receives an acquisition request for attribute information including an application ID from the information providing device 110, it returns the attribute information corresponding to the application ID included in the acquisition request to the information providing device 110.

The attribute information management unit 512 may obtain the attribute information DB 514 from an external information processing device or the like, and store and manage the attribute information DB 514 in a storage unit or the like. The attribute information management unit 512 may also obtain, for example, the behavioral histories of multiple users corresponding to multiple app IDs from the information providing device 110, classify the app IDs into multiple attributes using known cluster analysis or the like, and store and manage the attribute information DB 514.

Figure 7 shows an example of the attribute information DB 514 managed by the attribute information management unit 512. In the example of Figure 7, the attribute information DB 514 stores information such as "behavior history" and "attributes" for each app ID registered in the information provision system 100.

In the example of FIG. 7, the "behavioral history" stores information such as the type of content viewed by the user and the number of times the content was viewed. Additionally, the "attributes" store attributes that indicate the user's hobbies, preferences, tendencies, etc., obtained by analyzing the "behavioral history." Preferably, the "attributes" include multiple attributes.

The storage unit 507 is realized, for example, by the program executed by the CPU 201 in FIG. 2, the HD 204, the HDD controller 205, the RAM 203, etc., and stores various information and data such as the attribute information DB 514.

(About Broadcast ID)
Here, an overview of the broadcast ID included in the audio announcement or the like broadcast by the broadcast device 140 will be described.

Methods for embedding identification information such as a broadcast ID in sound waves such as voice announcements include transmitting the identification information in the inaudible range (e.g., 16 kHz to 20 kHz) close to ultrasound, and embedding the identification information in audio information in the audible range (e.g., 20 Hz to 16 kHz) (e.g., digital watermarking, etc.).

Digital watermarking involves embedding identification information in the audible range of audio such as voice announcements, and uses a technique known as steganography. Methods for embedding identification information in the audible range of audio information include, for example, spectrum spreading, echo, and modulation, and all of these methods embed identification information within a certain frequency range.

It is possible to set multiple fixed frequency ranges within the audible range. For example, within the audible range for the average person, which is about 20 Hz to 16 kHz, multiple coded frequency bands are created within the 100 Hz to 12 kHz range in which sound tends to spread easily with ordinary speakers.

The digital watermarking of this embodiment embeds identification information in audio announcements and the like by making subtle changes that are not discernible by humans. Therefore, it differs from technology that simply transmits identification information in a different frequency band (e.g., 16 kHz to 20 kHz, etc.).

Figure 8 is a diagram for explaining the broadcast ID according to the first embodiment. Figure 4 (A) shows an example of a frequency band in which the broadcast ID is embedded. A typical speaker (e.g., a speaker installed inside a bus vehicle) can output sound waves in the "audio frequency band" (e.g., 20 Hz to 20 kHz) between "extremely low frequency" and "ultrasonic wave" as shown in the "speaker playback range" of Figure 4 (A).

In the frequency range above 12 kHz, sound waves have a high linearity, making it difficult for the in-vehicle speakers installed in typical buses to transmit sound waves throughout the entire interior of the bus. In addition, this frequency range is susceptible to the influence of metallic sounds from coins and other currency used for paying fares.

In addition, the low frequency range of the audio frequency band (for example, the frequency range below 100 Hz) is easily affected by bus engine noise, tire road noise, etc.

Therefore, it is desirable that the broadcast ID embedded in the audio announcement as a digital watermark is embedded in the frequency range of the audio frequency band, for example, between 100 Hz and 12 kHz. This reduces the influence of the engine sound of the bus 105, road noise, etc., and makes it possible to notify the entire vehicle of the broadcast ID along with the audio announcement using existing in-vehicle speakers, etc.

However, the effects of engine sounds, road noise, etc., differ depending on the type of bus, and so this needs to be taken into consideration. Also, as shown in Figure 4 (A), it needs to be taken into consideration that the frequency range of about 100 Hz to 1 kHz is easily affected by human voices.

For this reason, it is desirable to divide the frequency range of 100 Hz to 12 kHz into multiple frequency bands and embed the broadcast ID in two or more frequency bands, as shown in FIG. 4(A), for example. The example in FIG. 4(a) shows an example in which the frequency range of 100 Hz to 12 kHz is divided into four frequency bands, f1 to f4, and identification information is embedded in each of the divided frequency bands. This allows the information terminal 120 to obtain the identification information contained in the other frequency bands f2 to f3, even if the information in frequency band "f1" is drowned out by the influence of engine noise, for example.

Figure 4 (B) shows an example of the timing for embedding the broadcast ID in the audio announcement. In the example of Figure 4 (B), the broadcast ID is embedded in the audio announcement as a digital watermark three times in frequency band f4 and three times in frequency band f2. This makes it possible to obtain the broadcast ID in the first half of the audio announcement, for example, even if the second half of the audio announcement is affected by noise.

In addition, since the broadcast ID is embedded as a digital watermark in multiple frequency bands, for example, if noise occurs in frequency band f4, the information terminal 120 can acquire the broadcast ID embedded in frequency band f2. Note that it is desirable that the broadcast IDs embedded in different frequency bands are embedded at different positions in time (at different timings). For example, in the example of FIG. 4(B), multiple broadcast IDs are embedded in frequency band f4 at a predetermined time interval (for example, one second intervals) from time t1, and multiple broadcast IDs are embedded in frequency band f2 at a predetermined time interval from time t2. This makes it possible to avoid the information terminal 120 processing multiple frequency bands simultaneously, and to reduce the processing load of the information terminal 120.

The broadcasting device 140 may broadcast the broadcast ID, for example, using the inaudible range of 16 kHz to 20 kHz. For example, frequencies above 16 kHz are difficult for the average person to hear, so when outputting (broadcasting) the broadcast ID at a location where voice announcements are not made frequently, such as a bus stop, it is desirable for the broadcasting device 140 to output (broadcast) the broadcast ID using the inaudible range. In this case, the broadcasting device 140 may represent a multi-bit broadcast ID by turning on and off sound waves of multiple frequencies above 16 kHz, for example, instead of using a digital watermark.

<Processing flow>
Next, a process flow of the information providing method according to the first embodiment will be described.

Figure 9 is a sequence diagram showing an example of processing of the information provision system according to the first embodiment. This processing shows an example of processing executed by the information provision system 100 when, for example, the broadcast device 140 in Figure 1 broadcasts an audio announcement including the broadcast ID "001".

In step S901, the sound wave analysis unit 523 of the information terminal 120a analyzes the audio announcement broadcast by the broadcast device 140 and extracts the broadcast ID "001."

In step S902, the terminal information transmission unit 524 of the information terminal 120a transmits terminal information including the broadcast ID "001" extracted by the sound wave analysis unit 523 and the application ID (e.g., "AP1") of the information terminal 120a to the information providing device 110.

In step S903, when the terminal information receiving unit 503 of the information providing device 110 receives the terminal information, the attribute information acquiring unit 504 transmits an acquisition request for attribute information including the application ID "AP1" contained in the terminal information to the attribute management device 130.

In step S904, when the attribute information management unit 512 of the attribute management device 130 receives a request to obtain attribute information from the information providing device 110, it obtains the attribute information "A3, B1, ..." corresponding to the application ID "AP1" from the attribute information DB 514.

In step S905, the attribute information management unit 512 of the attribute management device 130 transmits the acquired attribute information "A3, B1, ..." to the information providing device 110.

In step S906, when the identification unit 505 of the information providing device 110 receives the attribute information "A3, B1, ..." transmitted from the attribute management device 130, it identifies the content corresponding to the attribute information.

For example, the identification unit 505 uses the correspondence information 509 as shown in FIG. 6(C) to identify the broadcast ID "001" and the type of content "insurance information" that corresponds to the received attribute information "A3, B1, ...". The identification unit 505 also identifies the individual content "content A3" that corresponds to the broadcast ID "001" and the type of content "insurance information" from the content information 508 as shown in FIG. 6(A), for example.

As another example, when content information 508 as shown in FIG. 6(B) is stored in the memory unit 507 of the information providing device 110, the information providing unit 506 may acquire content corresponding to the attribute information from the content information 508. For example, the information providing unit 506 may acquire broadcast ID "001" and individual content "content A3" corresponding to the received attribute information "A3, B1, ..." from the content information 508 as shown in FIG. 6(B).

Furthermore, as described above, the identification unit 505 may identify content corresponding to the attribute information using a trained prediction model, etc.

In step S907, the information providing unit 506 of the information providing device 110 transmits the identified individual content "Content A3" to the information terminal 120a. At this time, the information providing unit 506 may transmit the common content "Introduction to the medical departments of Hospital A" corresponding to the broadcast ID to the information terminal 120a together with the identified individual content "Content A3".

In step S908, the display control unit 525 of the information terminal 120a causes the content "Content A3" transmitted from the information providing device 110 to be displayed on the display 317, etc.

When the display control unit 525 receives the common content "Introduction to the medical departments at Hospital A" together with the individual content "Content A3", it causes the common content "Introduction to the medical departments at Hospital A" and the individual content "Content A3" to be displayed on the display 317, etc.

Next, in step S911, the sound wave analysis unit 523 of the information terminal 120b analyzes the audio announcement broadcast by the broadcast device 140 and extracts the broadcast ID "001".

In step S912, the terminal information transmission unit 524 of the information terminal 120b transmits terminal information including the broadcast ID "001" extracted by the sound wave analysis unit 523 and the application ID (e.g., "AP2") of the information terminal 120b to the information providing device 110.

In step S913, when the terminal information receiving unit 503 of the information providing device 110 receives the terminal information, the attribute information acquiring unit 504 transmits an acquisition request for attribute information including the application ID "AP2" contained in the terminal information to the attribute management device 130.

In step S914, when the attribute information management unit 512 of the attribute management device 130 receives a request to obtain attribute information from the information providing device 110, it obtains the attribute information "A2, B2, ..." corresponding to the application ID "AP2" from the attribute information DB 514.

In step S915, the attribute information management unit 512 of the attribute management device 130 transmits the acquired attribute information "A2, B2, ..." to the information providing device 110.

In step S916, when the identification unit 505 of the information providing device 110 receives the attribute information "A2, B2, ..." transmitted from the attribute management device 130, it identifies the content corresponding to the attribute information.

For example, the identification unit 505 uses the correspondence information 509 as shown in FIG. 6(C) to identify the broadcast ID "001" and the type of content "pharmaceuticals" that corresponds to the received attribute information "A2, B2, ...". The identification unit 505 also identifies the individual content "content A2" that corresponds to the broadcast ID "001" and the type of content "pharmaceuticals" from the content information 508 as shown in FIG. 6(A), for example.

As another example, when content information 508 as shown in FIG. 6(B) is stored in the memory unit 507 of the information providing device 110, the information providing unit 506 may acquire content corresponding to the attribute information from the content information 508. For example, the information providing unit 506 may acquire broadcast ID "001" and individual content "content A2" corresponding to the received attribute information "A2, B2, ..." from the content information 508 as shown in FIG. 6(B).

Furthermore, as described above, the identification unit 505 may identify content corresponding to the attribute information using a trained prediction model, etc.

In step S917, the information providing unit 506 of the information providing device 110 transmits the identified individual content "Content A2" to the information terminal 120b. At this time, the information providing unit 506 may transmit the common content "Introduction to the medical departments of Hospital A" corresponding to the broadcast ID to the information terminal 120b together with the identified individual content "Content A2".

In step S918, the display control unit 525 of the information terminal 120b causes the content "Content A2" transmitted from the information providing device 110 to be displayed on the display 317, etc.

When the display control unit 525 receives the common content "Introduction to the medical departments at Hospital A" together with the individual content "Content A2", it causes the common content "Introduction to the medical departments at Hospital A" and the individual content "Content A3" to be displayed on the display 317, etc.

By performing the above process, the information providing device 110 can display different content depending on the attribute information on the information terminals 120a and 120b that have acquired the broadcast ID "001".

(Example of display screen)
FIG. 10 is a diagram illustrating an example of a display screen of the information terminal according to the first embodiment.

Fig. 10(A) shows an example of a display screen 1010 displayed by the information terminal 120a in step S908 of Fig. 9, for example. In the example of Fig. 10(A), the display screen 1010 displays common content "Introduction to the medical departments of Hospital A" 1011 and a medical insurance advertisement 1012, which is an example of individual content "Content A3".

Fig. 10(B) shows an example of a display screen 1020 displayed by the information terminal 120b in step S918 of Fig. 9, for example. In the example of Fig. 10(B), the display screen 1020 displays the common content "Introduction to the medical departments of Hospital A" 1011 and an advertisement 1021 for cold medicine, which is an example of the individual content "Content A2".

In this way, according to this embodiment, the information providing system 100 that provides content corresponding to broadcast content to the user's information terminal 120 can provide different content to various users.

Second Embodiment
<Functional configuration>
Fig. 11 is a diagram showing an example of a functional configuration of an information providing system according to the second embodiment. As shown in Fig. 11, the information providing device 110 according to the second embodiment has an attribute information management unit 512 which is included in the attribute management device 130 according to the first embodiment described in Fig. 5. Also, the storage unit 507 of the information providing device 110 stores an attribute information DB 514 which is stored in the storage unit 513 of the attribute management device 130 according to the first embodiment described in Fig. 5. In this manner, the attribute information DB 514 may be managed by the information providing device 110.

<Processing flow>
Fig. 12 is a sequence diagram showing an example of processing of the information providing system according to the second embodiment. This processing shows an example of processing executed by the information providing system 100 according to the second embodiment when, for example, the broadcasting device 140 in Fig. 1 broadcasts a voice announcement including the broadcast ID "001". Note that the basic processing content is similar to the processing of the information providing system according to the first embodiment described in Fig. 9, so detailed description of the processing similar to that of the first embodiment will be omitted here.

In step S1201, the sound wave analysis unit 523 of the information terminal 120a analyzes the audio announcement broadcast by the broadcast device 140 and extracts the broadcast ID "001."

In step S1202, the terminal information transmission unit 524 of the information terminal 120a transmits terminal information including the broadcast ID "001" extracted by the sound wave analysis unit 523 and the application ID (e.g., "AP1") of the information terminal 120a to the information providing device 110.

In step S1203, when the terminal information receiving unit 503 of the information providing device 110 receives the terminal information, the attribute information acquiring unit 504 acquires the attribute information "A3, B1, ..." corresponding to the application ID "AP1" from the attribute information managing unit 512.

In step S1204, the identification unit 505 of the information providing device 110 identifies content corresponding to the attribute information "A3, B1, ..." acquired by the attribute information acquisition unit 504. For example, the identification unit 505 identifies individual content "content A3" corresponding to the attribute information "A3, B1, ..." by processing similar to that of step S906 in FIG. 9.

In step S1205, the information providing unit 506 of the information providing device 110 transmits the identified individual content "Content A3" to the information terminal 120a.

In step S1206, the display control unit 525 of the information terminal 120a causes the content "Content A3" transmitted from the information providing device 110 to be displayed on the display 317, etc.

Next, in step S1211, the sound wave analysis unit 523 of the information terminal 120b analyzes the audio announcement broadcast by the broadcast device 140 and extracts the broadcast ID "001."

In step S1212, the terminal information transmission unit 524 of the information terminal 120b transmits terminal information including the broadcast ID "001" extracted by the sound wave analysis unit 523 and the application ID (e.g., "AP2") of the information terminal 120b to the information providing device 110.

In step S1213, when the terminal information receiving unit 503 of the information providing device 110 receives the terminal information, the attribute information acquiring unit 504 acquires the attribute information "A2, B2, ..." corresponding to the application ID "AP2" from the attribute information managing unit 512.

In step S1214, the identification unit 505 of the information providing device 110 identifies content corresponding to the attribute information "A2, B2, ..." acquired by the attribute information acquisition unit 504. For example, the identification unit 505 identifies individual content "content A2" corresponding to the attribute information "A2, B2, ..." by processing similar to that of step S916 in FIG. 9.

In step S1215, the information providing unit 506 of the information providing device 110 transmits the identified individual content "Content A2" to the information terminal 120b.

In step S1216, the display control unit 525 of the information terminal 120b causes the content "Content A2" transmitted from the information providing device 110 to be displayed on the display 317, etc.

When the display control unit 525 receives the common content "Introduction to the medical departments at Hospital A" together with the individual content "Content A2", it causes the common content "Introduction to the medical departments at Hospital A" and the individual content "Content A3" to be displayed on the display 317, etc.

In this way, the functional configuration of the information providing system 100 can be modified and applied in various ways. For example, the functional configuration of the information providing device 110 according to the first embodiment shown in FIG. 5 may be distributed among multiple information processing devices. Furthermore, the memory unit 507 provided in the information providing device 110 may be realized by another information processing device or an external cloud service, etc. Furthermore, the functions of the attribute management device 130 according to the first embodiment shown in FIG. 5 may be provided by an external cloud service, etc.

<Application example 1 of information provision system>
13A and 13B are diagrams showing an application example of an information providing system according to an embodiment of the present invention. Fig. 13A shows an example in which a broadcasting device 140 is provided in a bus 1310, and audio announcements are made in the bus using output devices 141a and 141b such as speakers.

Typically, inside bus 1310, audio announcements are broadcast including information about the next bus stop (e.g., "The next stop will be in front of Hospital A") and advertising information near the bus stop (e.g., "Pharmacy B is located in front of the main gate of Hospital A").

The broadcasting device 140 according to this embodiment uses this audio announcement to broadcast sound waves 142 including the broadcast ID inside the bus 1310. This allows the broadcasting device 140 to broadcast sound waves 142 including the broadcast ID with minimal capital investment by utilizing existing in-car broadcasting equipment installed inside the bus 1310. In addition, the information terminal 120 only needs to be equipped with a microphone, and there is no need to configure, for example, wireless LAN communication, short-range wireless communication, etc.

When the information terminals 120a and 120b acquire the broadcast ID contained in the sound waves 142 broadcast by the broadcast device 140, they transmit terminal information including the acquired broadcast ID and app ID to the information providing device 110.

In response to this, the information providing system 100 provides different content to the information terminals 120a, 120b according to the attributes of the users using the information terminals 120a, 120b, for example, by the processes described in Figures 9 and 12. This allows the information providing system 100 to display more appropriate advertising content on the information terminals 120a, 120b according to the hobbies, preferences, etc. of the users, thereby further improving the advertising effectiveness on the bus 1310. Furthermore, while with conventional audio advertising information, advertising fees can be obtained from only one advertiser, according to this embodiment, an advantage can be expected in that advertising fees can be obtained from more advertisers.

In addition, in the information providing system 100, by displaying web content such as that shown in Figs. 10(A) and (B) on the information terminals 120a and 120b, users can access a wider variety of content (e.g., "quote," "request for information," etc.). This allows advertisers to more appropriately evaluate the effectiveness of their advertising, i.e., the extent to which the advertising content provided by the information providing system 100 resulted in quotes, requests for information, and even product contracts and purchases.

In addition, the information providing system 100 can provide more appropriate advertising content to users by updating user attribute information based on information such as what content each user accessed, how many times the content was accessed, and when the content was accessed.

In this embodiment, such tallying and updating of attribute information is performed based on the application ID. This application ID does not include personal information of the user or information that identifies the information terminal 120, so the information providing system 100 according to this embodiment can tally access information and update attribute information without relying on personal information of the user or information of the information terminal 120.

Figure 13 (B) shows an example in which a broadcasting device 140 is provided at a bus stop 1320 or the like, and sound waves 142 including a broadcast ID are broadcast (output) using an output device 141 such as a speaker. Generally, voice announcements are not broadcast frequently at a bus stop 1320 as they are inside a bus 1310, so at the bus stop 1320, it is desirable for the broadcasting device 140 to broadcast (output) sound waves 142 including a broadcast ID at a frequency of, for example, 16 kHz or higher.

In this case, when the information terminals 120a and 120b acquire the broadcast ID contained in the sound waves 142 broadcast by the broadcast device 140, they transmit terminal information including the acquired broadcast ID and app ID to the information providing device 110.

In response to this, the information providing device 110 provides different content to the information terminals 120a and 120b from among content for users waiting for the bus 1310 at the bus stop 1320, depending on the attributes of the users using the information terminals 120a and 120b. For example, the information providing device 110 can display on the information terminals 120a and 120b information according to the hobbies and preferences of the users, such as information on events held by local governments, information on exhibitions held by companies, etc., and the timetable for the bus 1310, depending on the attributes of the users of the information terminals 120a and 120b.

<Application example 2 of information provision system>
Fig. 14 is a diagram (2) showing an application example of the information provision system according to an embodiment. Fig. 14(A) shows an example in which a broadcasting device 140 is provided in a train 1410 such as an electric train, and sound waves including different broadcast IDs are output for each train using output devices 141a, 141b, and 141c such as speakers.

Generally, even within the carriages of train 1410, a voice announcement including information about the next station to stop at (for example, "The next stop is XX station. The exit is on the right") is broadcast. Therefore, even within the carriages of train 1410, this voice announcement can be used to broadcast sound waves including a broadcast ID within the carriages of train 1410.

As a result, even inside the carriages of train 1410, as described in FIG. 13, for example, information providing device 110 can cause information terminals 120a and 120b to display different content depending on the attributes of the users of information terminals 120a and 120b.

In addition, in the case of train 1410, for example, as shown in FIG. 14(A), by outputting sound waves containing a different broadcast ID for each vehicle, it becomes possible to operate the train 1410 in a different way than in the case of bus 1310. Here, the explanation will focus on the differences with the application to bus 1310.

For example, as shown in FIG. 14(B), a specific broadcast ID (e.g., broadcast ID0) is embedded in the departure melody (or departure sound) that is broadcast before a train departs on station platform 1420. Furthermore, when information terminal 120 acquires broadcast ID0, it is set to start processing of an information processing system such as that shown in FIG. 9.

After the information terminal 120 acquires the broadcast ID 0, for example, when the user boards the train 1410 as shown in FIG. 14(A), different content is provided to the information terminals 120a and 120b depending on the car that the user boards.

Using this, the information provision system 100 can provide content (common content or individual content) so that a user can receive different incentives depending on the vehicle they are riding in, for example.

Examples of incentives may include points being given to the information terminal 120 of a user who rides in a specified vehicle, or a discount on the fare at a specified frequency. Alternatively, the information terminal 120 of a user who rides in a specified vehicle may be given access rights to use specified content.

Using such a mechanism, the railway company operating the train 1410 can, for example, set up more attractive incentives in cars that are relatively empty, thereby leveling out the occupancy rates of each car.

In addition, the railway company or the like may provide information about other cars with more vacant seats to the information terminal 120a of a user who is in a car with no vacant seats. In this case, even if it is difficult for the user to move to another car with more vacant seats, the user can obtain information about cars with relatively more vacant seats, and the next time the user boards the same train 1410, the user can change the location of the boarding area to a location with more vacant seats, etc.

As described above, according to each embodiment of the present invention, in an information providing system that provides content corresponding to broadcast content to a user's information terminal, it becomes possible to provide different content to various users.

In the above embodiments, examples of application to buses, trains, etc. have been described, but the information provision system 100 according to this embodiment can also be applied to various transport vehicles, such as taxis, airplanes, ships, etc.

In addition, the information provision system 100 according to this embodiment is not limited to transportation equipment, but can also be applied to various facilities (e.g., medical facilities, commercial facilities, offices, factories, etc.) and city streets, etc.

In addition, as identification information for identifying the broadcast content, identification information related to the output device 141 or the broadcast device 140 (such as the ID of the device or equipment, the installation location of these, or the ID of the operating route or line of the vehicle broadcasting) may be used, and the sound wave analysis unit 523 described above may extract this information by processing similar to that described above.
