As a result, convenience for travelers is improved, and safe and comfortable travel can be realized.

Specific embodiments will be described in more detail below with reference to the drawings.

[First embodiment]
The first embodiment will be described in more detail with reference to the drawings.

[System configuration]
FIG. 2 is a diagram showing an example of a schematic configuration of an information providing system according to the first embodiment. As shown in FIG. 2, the information providing system includes a communication platform, a biometric authentication platform, and a data analysis platform.

The communication platform is a system that provides users with connections with others. The communication infrastructure implements a so-called SNS (Social Networking Service).

Users send and receive messages (text), photos, videos, etc. with others via the communication platform. In addition, users receive information from organizations such as companies and local governments through the communication infrastructure.

The communication infrastructure includes the exchange server 10. The exchange server 10 implements the main functions of the communication infrastructure. The exchange server 10 realizes message exchange between users.

The biometric authentication infrastructure is a system that provides biometric authentication services to service providers (retail stores, hotels, etc.). For example, authentication terminals and signage are installed in service providers such as tourist spots. The authentication terminal or the like acquires the user's biometric information (for example, face image) and transmits the acquired biometric information to the biometric authentication infrastructure. The biometric authentication infrastructure performs biometric authentication using the acquired biometric information.

Service providers participating in the information provision system provide services using biometric authentication. Examples of services provided by service providers include payment services at retail stores and lodging services at hotels and the like. Alternatively, the service provided by the service provider may be immigration control at an airport or port. The service provider disclosed in the present application should be able to provide any service that can be provided using biometric authentication.

The biometric authentication infrastructure includes the authentication server 20. The authentication server 20 is a server that performs biometric authentication. The authentication server 20 implements the main functions of the biometric authentication infrastructure.

The user's biometric information includes, for example, data (feature amounts) calculated from physical features unique to an individual, such as the face, fingerprint, voiceprint, veins, retina, and iris pattern of the pupil. Alternatively, the user's biometric information may be image data such as a face image or a fingerprint image. A user's biometric information should just contain a user's physical characteristic as information. In the first embodiment, biometric information is a face image of a person or a feature amount generated from the face image.

The data analysis platform is a system that analyzes the information generated by the information provision system. The data analysis platform analyzes data exchanged between friends (messages, photos, etc.) and data generated by biometric authentication. The data analysis infrastructure generates useful information for users by analyzing data. The data analysis infrastructure provides the generated useful information to the user via the communication infrastructure.

The data analysis infrastructure includes the analysis server 30. The analysis server 30 is a server that analyzes data generated in the system. The analysis server 30 implements the main functions of the data analysis infrastructure.

Of the above three platforms, the communication platform functions as a front end that provides the user with an interface for the entire system. The biometric authentication infrastructure and data analysis infrastructure function as backends that process data obtained from the communication infrastructure. That is, the user can acquire useful information through the communication infrastructure without being aware of the existence of the biometric authentication infrastructure and the data analysis infrastructure.

The servers (exchange server 10, authentication server 20, analysis server 30) included in each infrastructure shown in FIG. 2 are configured to communicate with each other via a network. For example, the exchange server 10 and the authentication server 20 are connected by wired or wireless communication means, and are configured to be able to communicate with each other.

FIG. 2 is an example and is not intended to limit the configuration of the information providing system disclosed in the present application. For example, a communication infrastructure may include two or more exchange servers 10 . In addition, only server devices (exchange server 10, authentication server 20, analysis server 30), which are the main components, are shown for various platforms, and other components (for example, database server etc.) are omitted.

[Overview of operation]
Next, a schematic operation of the information providing system according to the first embodiment will be described. Here, the operation of the information providing system will be described by taking as an example the provision of information when a user travels to a tourist spot. More specifically, the overall operation of the information providing system will be explained according to a schedule from when a traveler visits a tourist spot, takes a tour of the tourist spot, and returns home.

Explanations regarding preparations for users to use the communication infrastructure (SNS) independently will be omitted. A user of the communication infrastructure is assigned a user ID (IDentifier). For example, user A is assigned a user ID such as "ID01", and user B is assigned a user ID such as "ID02". A terminal possessed by each user stores the owner's user ID and the user IDs of others (for example, friends). The exchange server 10 also associates and stores the user ID and the contact information (for example, telephone number, mail address, etc.) of the terminal possessed by the user corresponding to the user ID.

The data analysis platform (analysis server 30) provides various information to the user based on a "scenario" prepared in advance. A scenario is composed of a combination of conditions (trigger) for providing information and contents (actions) to be executed when the conditions are met.

For example, "If you arrive at tourist spot A, guide you to tourist spot B" corresponds to a scenario. In this case, "arrive at tourist spot A" is the trigger, and "guide to tourist spot B" is the action.

<Before travel>
A user who uses the information providing system needs to register with the system (user registration) in advance. Specifically, the user needs to register information such as travel destinations in the system. In other words, by registering travel destination information and the like in the system, the user can obtain useful information in each step of the trip (before, after, and during the trip).

For example, users (travelers) may collect their own biometric information (e.g. face image), personal information (e.g. name, age, gender, address, credit card information, etc.), travel information (e.g. accommodation hotel name, length of stay, etc.) into the communication platform. More specifically, the user inputs biometric information, personal information, travel information, etc. to the communication platform using the terminal 40 that the user possesses (see FIG. 3).

The exchange server 10 transmits the user ID and various information (biometric information, personal information, travel information) acquired from the user's terminal 40 to the authentication server 20. More specifically, the exchange server 10 transmits to the authentication server 20 a "user registration request" including the user ID and various information.

Upon receiving the user registration request, the biometric-based authentication server 20 associates and stores the acquired user ID, biometric information, personal information, travel information, and the like. The authentication server 20 also generates a feature amount from the face image as necessary, and stores the generated feature amount and the user ID or the like in association with each other.

Thus, the exchange server 10 acquires at least the biometric information of the user, and transmits a "user registration request" including the acquired biometric information to the authentication server 20. The authentication server 20 stores the biometric information (face image or feature amount) included in the user registration request.

Further, the exchange server 10 transmits the user ID and the acquired information (biological information, personal information, travel information) to the analysis server 30. More specifically, the exchange server 10 transmits a "user registration notification" including the user ID, personal information, and travel information to the analysis server 30 (see FIG. 4). That is, the exchange server 10 transmits a user registration notification including the personal information of the user to the analysis server 30 in response to transmitting the user registration request to the authentication server 20 .

By receiving the user registration notification, the analysis server 30 acquires the personal information and travel information of the user planning the trip.

Upon receiving the user registration notification, the analysis server 30 of the data analysis infrastructure starts managing the user's action history. Specifically, the analysis server 30 adds a new entry to the action history database. Details of the action history database will be described later.

Upon receiving the user registration notification, the analysis server 30 generates "pre-trip information" based on the acquired travel information. In this case, the analysis server 30 generates pre-trip information based on the scenario.

　Pre-trip information includes useful information for users before the trip. For example, the analysis server 30 identifies a tourist destination to be visited from the travel information, and generates information regarding tourist spots and the like of the identified tourist destination as “pre-trip information”. Alternatively, the analysis server 30 may generate pre-trip information including information (for example, transfer guidance, etc.) regarding movement to a tourist spot. In the above example, "If user registration is performed, provide information on tourist spots at the travel destination" and "If user registration is performed, provide transfer information to sightseeing spots". corresponds to the scenario.

The analysis server 30 transmits the generated pre-trip information (for example, information about sightseeing spots, etc.) to the communication infrastructure together with the user ID.

The exchange server 10 identifies the user (user's terminal 40) based on the user ID, and transmits (transfers) the pre-trip information to the identified user's terminal 40.

The user checks the pre-trip information provided by the data analysis platform on the communication platform (SNS).

<During travel>
A user (tourist) posts a message or the like to the communication platform at a sightseeing spot, tourist spot, or the like. Specifically, the user operates the terminal 40 to tell a friend about his or her impressions of visiting a tourist spot, or to send photos, videos, etc. of the tourist spot to the friend. At that time, the terminal 40 transmits a message (text), a photograph, etc. to the communication infrastructure together with the user ID of its own terminal and the user ID of the partner terminal (the terminal 40 of the friend or the like) (see FIG. 5).

The exchange server 10 of the communication infrastructure transmits the received user ID (message sender's user ID), message, photo, etc. to the data analysis infrastructure.

The analysis server 30 of the data analysis platform analyzes the received messages, photos, etc. The analysis server 30 estimates the behavior, situation, etc. of the user (message sender) by analyzing the message and the like. For example, when the analysis server 30 receives a message indicating that the user has boarded a means of transportation such as an airplane or a railway, the analysis server 30 determines that the user is "in transit".

Alternatively, when the analysis server 30 receives a message indicating that the user has arrived at a tourist spot or tourist spot, it determines that the user has "arrived at a tourist spot (tourist spot)".

The analysis server 30 stores the estimated user's behavior and situation in the behavior history database.

In addition, the analysis server 30 may generate useful "traveling information" for users who are traveling, triggered by the reception of a message or the like.

For example, when it is determined that the user has arrived at a tourist spot according to the latest behavior of the user (the latest information registered in the action history database), the analysis server 30 Generate information. Alternatively, the analysis server 30 may generate travel information including a message welcoming a visit to a tourist spot, a history of the tourist spot, and the like. The analysis server 30 transmits the generated travel information together with the user ID to the communication infrastructure.

The exchange server 10 transmits travel information to the terminal 40 corresponding to the user ID.

Here, users may receive services using biometric authentication at tourist spots (see Figure 6). More specifically, the user receives a service based on biometric authentication using the authentication terminal 50 installed in the storefront of a service provider operating at a tourist spot in a tourist spot or in a hotel lobby.

The authentication terminal 50 acquires the biometric information of the user (tourist; person to be authenticated). The authentication terminal 50 transmits an authentication request including the biometric information to the authentication server 20 .

The authentication server 20 executes biometric authentication using the acquired biometric information and the pre-registered biometric information, and transmits the authentication result to the authentication terminal 50.

The authentication terminal 50 performs processing according to the authentication result. If the authentication succeeds, the authentication terminal 50 performs check-in procedures and the like. For example, the authentication terminal 50 performs the check-in procedure while displaying a message welcoming the visitor of the person to be authenticated together with the name of the person to be authenticated. If the authentication fails, the authentication terminal 50 notifies the user to that effect.

When biometric authentication succeeds, the biometric authentication platform (authentication server 20) sends an "authentication success notification" to the data analysis platform. The authentication success notification includes the user ID of the authenticated person (user determined to be authenticated successfully) and details of biometric authentication. The details of biometric authentication (detailed authentication information) include information such as the installation location of the authentication terminal 50 and the services provided. For example, when a user performs a check-in procedure using an authentication terminal 50 installed in a hotel, detailed authentication information stating that effect is sent to the analysis server 30 .

Upon receiving the authentication success notification, the analysis server 30 analyzes the detailed authentication information to estimate the behavior, situation, etc. of the user (person to be authenticated). For example, in the above example, the analysis server 30 determines that the user has arrived at the hotel. The analysis server 30 stores the behavior of the user in the behavior history database.

The analysis server 30 may generate travel information upon receipt of the authentication success notification. In the above example, the analysis server 30 may generate recommendation information for sightseeing spots around the hotel, or may generate recommendation information regarding meals. That is, travel information may be generated according to a scenario consisting of a condition (trigger) of "arrived at a hotel" and a content (action) of "provide recommended information on sightseeing spots around the hotel".

In this way, the authentication server 20 receives an authentication request including the biometric information of the person to be authenticated from the authentication terminal 50, and performs biometric authentication using the biometric information included in the authentication request and the stored biometric information. When the biometric authentication is successful, the authentication server 20 transmits an authentication success notification including details regarding the successful biometric authentication to the analysis server 30 .

<After the trip>
When the analysis server 30 determines that the user has completed the trip from the information obtained from the communication infrastructure (such as a message sent to a friend) or the information obtained from the biometric authentication infrastructure (authentication success notification), it generates post-travel information. do. The post-trip information is useful information for the user after the trip.

For example, if the analysis server 30 determines that the user has returned home by analyzing the message obtained from the communication infrastructure, it stores this fact in the action history database. Furthermore, the analysis server 30 generates post-trip information.

For example, the analysis server 30 may generate post-trip information about the next travel destination, or generate post-trip information such as information for looking back on the current trip (album like a collection of photos taken during the trip). may

In addition, post-trip information is also generated based on the "scenario". In the above example, post-travel information is generated by a scenario consisting of the condition "user returns home" and the content "provide information on next travel destination".

The analysis server 30 transmits the generated post-trip information to the user's terminal 40 via the communication infrastructure (see FIG. 7).

As described above, the analysis server 30 receives the first data (messages, photos, videos, etc. sent to friends) acquired from the exchange server 10 and/or the second data generated by the authentication server 20 (authentication Information to be provided to the user is generated based on the notification of success. The analysis server 30 transmits the generated provided information (pre-trip information, during-trip information, post-trip information) to the exchange server 10 . The exchange server 10 transfers the provided information generated by the analysis server 30 to the terminal 40 owned by the user. When generating the provided information, the analysis server 30 estimates the behavior of the user by analyzing the first data and/or the second data. The analysis server 30 executes the contents of the corresponding scenario when the estimated behavior matches the conditions of the scenario.

After that, the person-to-be-authenticated management unit 302 calculates the position of each feature point and the distance between each feature point as a feature amount, and generates a feature vector (vector information that characterizes the face image) composed of a plurality of feature amounts.

The authenticated person management unit 302 associates the user ID obtained from the communication platform with the feature amount (biometric information) generated above, personal information, and travel information, and stores them in the authenticated person information database (see FIG. 12).

The authenticated person information database shown in FIG. 12 is an example, and is not meant to limit the items to be stored. For example, a "face image" may be registered in the authentication subject information database as biometric information.

The authentication unit 303 is means for processing an authentication request from the authentication terminal 50.

Upon receiving the authentication request, the authentication unit 303 sets the biometric information (feature amount) included in the authentication request as a matching target, and performs matching processing with the biometric information registered in the authenticated person information database. More specifically, the authentication unit 303 sets the feature amount extracted from the authentication request as a matching target, and executes 1:N matching with a plurality of feature amounts registered in the authenticated person information database. (N is a positive integer, the same below).

The authentication unit 303 calculates the degree of similarity between the feature quantity (feature vector) to be matched and each of the plurality of feature quantities on the registration side. Chi-square distance, Euclidean distance, or the like can be used for the degree of similarity. Note that the greater the distance, the lower the similarity, and the closer the distance, the higher the similarity.

If a feature amount with a degree of similarity equal to or higher than a predetermined value is not registered in the authentication-subjected person information database, the authentication unit 303 sets the authentication result to "authentication failure". In the case of authentication failure, the authentication unit 303 transmits a negative response to that effect to the authentication terminal 50 .

If a feature amount with a degree of similarity greater than or equal to a predetermined value is registered in the authentication-subjected person information database, the authentication unit 303 sets the authentication result to "successful authentication". In the case of authentication success, the authentication unit 303 performs processing according to the type of the authentication terminal 50 that is the source of the authentication request.

For example, if the authentication terminal 50 is a check-in terminal installed in a hotel, the authentication unit 303 selects the travel information of the entry having the biometric information with the highest degree of similarity to the matching target among the entries in the authentication subject information database. Send an acknowledgment to the authentication terminal 50 containing

Alternatively, if the authentication terminal 50 is a payment terminal installed in a retail store, the authentication unit 303 checks the credit card information of the entry having the biometric information with the highest degree of similarity to the matching target among the entries in the authentication subject information database. to the authentication terminal 50.

Also, in the case of successful authentication, the authentication unit 303 transmits detailed authentication information to the analysis server 30 together with the user ID of the entry specified by the matching process. For example, authentication detailed information including the installation location of the authentication terminal 50 where biometric authentication was performed (e.g. hotel name, retail store name), the purpose of biometric authentication (e.g. check-in procedure, product payment), etc. is sent to the analysis server 30. be done.

The storage unit 304 is means for storing information necessary for the operation of the authentication server 20 . An authenticated person information database is constructed in the storage unit 304 .

[Analysis server]
FIG. 13 is a diagram showing an example of a processing configuration (processing modules) of the analysis server 30 according to the first embodiment. Referring to FIG. 13 , the analysis server 30 includes a communication control section 401 , a user information management section 402 , an analysis section 403 , an information provision section 404 and a storage section 405 .

The communication control unit 401 is means for controlling communication with other devices. For example, the communication control unit 401 receives data (packets) from the exchange server 10 . Also, the communication control unit 401 transmits data to the exchange server 10 . The communication control unit 401 transfers data received from other devices to other processing modules. The communication control unit 401 transmits data acquired from other processing modules to other devices. In this manner, other processing modules transmit and receive data to and from other devices via the communication control unit 401 . The communication control unit 401 has a function of a receiving unit that receives data generated in the system, and a function of a transmitting unit that transmits the generated provided information to the terminal 40 owned by the user.

The user information management unit 402 is means for managing user information (user ID, personal information, travel information) acquired from the communication infrastructure. The user information management unit 402 associates the user ID, personal information, and travel information acquired from the communication infrastructure and stores them in the user information database (see FIG. 14).

The analysis unit 403 is means for analyzing data acquired from the communication infrastructure and the biometric authentication infrastructure. The analysis unit 403 analyzes the data generated in the system and estimates the behavior of the user. More specifically, the analysis unit 403 analyzes data (at least one of messages, photographs, and moving images) acquired from the communication infrastructure, and estimates the behavior and state of the user.

When the analysis unit 403 receives the "user registration notification" from the exchange server 10, it adds a new entry to the action history database. Furthermore, the analysis unit 403 sets "user registration completed" in the action history field of the added entry (see the top and bottom of FIG. 15). Note that, as shown in FIG. 15, the action history database stores the user ID, the date and time (the date and time when the message or the like was analyzed), and the action history in association with each other.

The analysis unit 403 acquires from the exchange server 10 messages, photos, videos, etc. that are exchanged between the user and the friend. The analysis unit 403 estimates the behavior and situation of the user from the obtained message or the like. Specifically, the analysis unit 403 estimates the user's behavior and situation by referring to the table information that stores the wording (sentence) included in the message and the action and situation estimated from the wording in association with each other. (See FIG. 16).

Alternatively, the analysis unit 403 may use a learning model prepared in advance to estimate the behavior and situation of the user. A system administrator or the like prepares a large amount of teaching data in which labels (user's actions, situations) are assigned to messages and the like. The administrator or the like performs machine learning using the teacher data to generate a classification model (learning model). Arbitrary algorithms such as support vector machines, boosting, and neural networks can be used to generate learning models. Since well-known techniques can be used for algorithms such as the support vector machine, the description thereof is omitted.

The generated learning model is implemented in the analysis server 30. By inputting a message or the like into the learning model, the analysis unit 403 acquires the behavior and situation of the user estimated from the message.

The analysis unit 403 may estimate the behavior and situation of the user based on the "authentication success notification" obtained from the authentication server 20. For example, when the analysis unit 403 receives an authentication success notification including information indicating that the check-in procedure has been performed at the authentication terminal 50, the analysis unit 403 estimates that the user's action is "arrived at the hotel."

The analysis unit 403 registers the estimated user's behavior and situation in the behavior history database. As shown in FIG. 15, the action history database manages and stores user actions and situations in chronological order.

When the analysis unit 403 adds an entry to the action history database or adds an action history, the analysis unit 403 notifies the information provision unit 404 to that effect. The analysis unit 403 transmits a notification of action history database update to the information provision unit 404 .

The information providing unit 404 is means for providing information to users. The information providing unit 404 generates provided information (pre-trip information, during-trip information, and post-trip information) to be provided to the user according to a "scenario" prepared in advance. The information providing unit 404 functions as a generating unit that generates provided information to be provided to the user according to the behavior of the user.

It should be noted that the scenario is prepared by a system administrator or the like and input to the analysis server 30 in advance. Alternatively, the analysis server 30 may acquire scenarios by accessing other external servers or database servers.

As described above, a scenario consists of a combination of the conditions that trigger the provision of information (trigger) and the contents (actions) that are performed when the conditions are met. Upon receiving the action history database update notification from the analysis unit 403, the information provision unit 404 refers to the scenario database that stores the scenario (see FIG. 17).

The information providing unit 404 refers to the scenario database, and executes the corresponding content (action) if the user's behavior or situation corresponds to the conditions (trigger) described in the database.

Specific examples of information provision in each process before, during, and after the trip are described below. The information providing unit 404 determines whether the behavior of the user corresponds to any of the behavior before the trip, the behavior during the trip, and the behavior after the trip, and generates provided information corresponding to each step. In other words, in the scenario, the user's actions performed in each process of the trip (before, during, and after the trip) are described as "conditions", and when the conditions are met, the user in each process Information assumed to be useful for is generated as provided information.

The information providing unit 404 can acquire the user's travel destination, address, etc. by searching the user information database using the user ID of the action history database. Information necessary for information provision, such as a list of sightseeing spots included in the sightseeing spot, is stored in the storage unit 405 .

<Specific examples of pre-trip information>
For example, if the user's action is "completion of user registration", the information providing unit 404 generates guidance regarding a sightseeing spot that the user plans to visit as "pre-trip information". For example, if the information providing unit 404 finds that the user will visit tourist spot A based on the travel information acquired from the communication platform, it generates a list of tourist spots included in tourist spot A as pre-trip information. do.

The generated pre-trip information is sent to the user's terminal 40 via the communication infrastructure. In this case, the user's terminal 40 displays a message as shown in FIG.

Alternatively, the information providing unit 404 may generate pre-trip information such as route guidance to the travel destination and fees based on the user's address and travel destination.

Alternatively, the information providing unit 404 may generate pre-trip information that enables a specific function in the communication infrastructure. For example, the information providing unit 404 may generate pre-trip information such as setting a travel schedule in a calendar or pre-trip information such as a reminder several days before the trip.

<Specific example of travel information>
For example, when the user arrives at a tourist spot, the information providing unit 404 may generate guidance on the most popular tourist spots in the tourist spot as travel information. The generated travel information is transmitted to the user's terminal 40 via the communication infrastructure. In this case, the user's terminal 40 displays a message as shown in FIG. Note that as shown in FIG. 19, illustrations of sightseeing spots and the like may be included in the travel information.

Alternatively, when the user arrives at a tourist spot, the information providing unit 404 generates information on specialties, specialties, etc. of the tourist spot and information on events (for example, traditional events such as festivals) as travel information. good too.

Alternatively, when the user arrives at a sightseeing spot (station, airport), the information providing unit 404 may generate, as travel information, information related to a taxi for the user to move (such as the contact information of a taxi company). good.

Alternatively, when the user arrives at a hotel reserved by the user, the information providing unit 404 may generate information about the hotel and restaurants around the hotel as travel information.

<Specific examples of post-trip information>
For example, when the user returns home, the information providing unit 404 generates guidance regarding the next trip as post-trip information. The generated post-trip information is transmitted to the user's terminal 40 via the communication infrastructure. In this case, the user's terminal 40 displays a message as shown in FIG.

Alternatively, when the user returns home, the information providing unit 404 generates post-trip information that looks back on the current trip. For example, the information providing unit 404 refers to the action history database, collects photos taken during the trip, and generates an “album” as post-trip information.

Alternatively, the information providing unit 404 may generate post-travel information about the expenses required for the trip if payment information (the amount of money spent at the travel destination) is recorded in the action history database.

In this way, the information providing unit 404 generates useful pre-trip information for the user before the trip when the user's behavior is presumed to be the behavior before the trip. When the user's behavior is presumed to be a behavior during a trip, the information providing unit 404 generates during-travel information useful for the user during the trip. When the behavior of the user is presumed to be the behavior after the trip, the information providing unit 404 generates post-trip information beneficial to the user after the trip.

<Information provision using attribute information>
The information providing unit 404 may generate provided information (pre-trip information, during-trip information, post-trip information) based on attribute information such as age and sex of the user. For example, the information providing unit 404 may change the sightseeing spot to be recommended during the trip or the sightseeing spot to be recommended after the trip depending on the age or sex of the user.

In this case, the scenario database contains information such as "When a man in his 30s arrives at tourist spot A, guide him to tourist spot B" and "When a woman in her 20s arrives at tourist spot A, guide him to tourist spot C." is registered. That is, more detailed conditions than those shown in FIG. 17 may be set in the scenario database.

<Provision of information using time zones>
The information providing unit 404 may generate the provided information based on the time (time period) at which the provided information is generated. For example, the information providing unit 404 may change the sightseeing spots recommended during the trip depending on the time period.

In this case, in the scenario database, "If you arrive at tourist spot A in the morning, guide you to tourist spot B" or "If you arrive at tourist spot A in the afternoon, guide you to tourist spot C". Such a scenario is registered.

<Information provision using weather information>
The information providing unit 404 may generate the provided information based on the weather (weather forecast) at the time of generating the provided information. For example, the information providing unit 404 may change the sightseeing spots recommended during the trip depending on the weather. Note that the information providing unit 404 can acquire weather information by accessing an external server or the like.

In this case, in the scenario database, "If the weather is fine when arriving at tourist spot A, guide to tourist spot B" or "If it is raining when arriving at tourist spot A, guide to tourist spot C". Such a scenario is registered.

<Information provision using action history>
The information providing unit 404 may generate information to be provided to the user based on the user's action history. For example, the information providing unit 404 may change the restaurant to be guided during dinner according to the user's lunch category (Japanese food, Chinese food, etc.).

In this case, scenarios such as "If you have Japanese lunch, guide you to restaurant B" or "If you have Chinese lunch, guide you to restaurant C" are registered in the scenario database.

The storage unit 405 is means for storing information necessary for the operation of the analysis server 30. A user information database, an action history database, a scenario database, and the like are constructed in the storage unit 405 .

[Terminal]
Since the configuration and functions of the terminal 40 are obvious to those skilled in the art, the description thereof is omitted. The terminal 40 should be able to provide information to the user using the SNS provided by the communication infrastructure. Examples of the terminal 40 include mobile terminal devices such as smartphones, mobile phones, game machines, and tablets, and computers (personal computers, notebook computers).

[Authentication terminal]
Since the configuration and functions of the authentication terminal 50 are obvious to those skilled in the art, the description thereof will be omitted. The authentication terminal 50 acquires the biometric information of the person to be authenticated, and transmits the biometric information (for example, face image) to the authentication server 20 . The authentication terminal 50 performs necessary processing according to information (for example, travel information, credit card information, etc.) received from the authentication server 20 . For example, the authentication terminal 50 uses travel information to perform check-in procedures, and uses credit card information to process product payment.

[System operation]
Next, operation of the information providing system according to the first embodiment will be described. A description of the operation related to user registration is omitted.

FIG. 21 is a sequence diagram showing an example of the operation of the information providing system according to the first embodiment. A case where the data analysis infrastructure (analysis server 30) provides information based on a message acquired from the communication infrastructure (exchange server 10) will be described with reference to FIG.

When the exchange server 10 receives a message sent and received between users, it sends the message to the analysis server 30 (step S01).

The analysis server 30 analyzes the received message and estimates the behavior and situation of the user (step S02). The analysis server 30 analyzes at least one of messages, photographs, and moving images exchanged between users, and estimates the actions and situations of the users.

The analysis server 30 refers to the scenario DB (Data Base) and determines whether or not the user's behavior matches the predetermined scenario conditions (step S03).

If the scenario database contains a scenario that matches the behavior of the user, the analysis server 30 executes the action of the scenario and generates provision information to be provided to the user (step S04).

The analysis server 30 transmits the generated provided information (travel information, etc.) to the exchange server 10 together with the user ID of the user (the user ID of the user who transmitted the message to the communication infrastructure) (step S05).

The exchange server 10 transfers the provided information acquired from the analysis server 30 to the terminal 40 corresponding to the user ID (step S06).

FIG. 22 is a sequence diagram showing an example of the operation of the information providing system according to the first embodiment. A case where the data analysis infrastructure (analysis server 30) provides information based on the authentication success notification acquired from the biometric authentication infrastructure (authentication server 20) will be described with reference to FIG.

The authentication server 20 executes biometric authentication in response to the authentication request from the authentication terminal 50 (step S11).

In the case of authentication success, the authentication server 20 transmits an authentication success notification to the analysis server 30 (step S12).

The analysis server 30 analyzes the received authentication success notification and estimates the user's behavior and situation (step S13). The analysis server 30 analyzes data (authentication success notification) generated by biometric authentication in which the user is the person to be authenticated.

The analysis server 30 refers to the scenario database and determines whether or not the user's behavior matches the predetermined scenario conditions (step S14).

If the scenario database contains a scenario that matches the behavior of the user, the analysis server 30 executes the action of the scenario and generates provision information to be provided to the user (step S15).

The analysis server 30 transmits the generated provided information (travel information, etc.) to the exchange server 10 together with the user ID of the user (the user ID of the user who transmitted the message to the communication infrastructure) (step S16).

The exchange server 10 transfers the provided information acquired from the analysis server 30 to the terminal 40 corresponding to the user ID (step S17).

As described above, the information providing system according to the first embodiment analyzes data generated in the system (data sent to friends and data generated as a result of biometric authentication) to provide useful information for users. (eg, pre-trip information, mid-trip information, post-trip information). The generated provided information is provided to the user via SNS (message exchange type) that the user uses on a daily basis. That is, the user can access the provided information through a familiar interface, and does not need to use an interface for obtaining the provided information. The user can access useful information through the SNS that the user is familiar with on a daily basis, thereby improving convenience for the user.

Also, the analysis server 30 according to the first embodiment determines whether the user corresponds to "before travel", "during travel", or "after travel" according to the user's behavior. The analysis server 30 generates and provides useful information to the user of each process according to the determined situation. In other words, the information providing system according to the first embodiment provides timely and useful information (information required by the user) in consideration of the situation of the user (traveler). As a result, safe and comfortable travel can be realized.

Next, the hardware of each device that makes up the information provision system will be explained. FIG. 23 is a diagram showing an example of the hardware configuration of the analysis server 30. As shown in FIG.

The analysis server 30 can be configured by an information processing device (so-called computer), and has a configuration illustrated in FIG. For example, the analysis server 30 includes a processor 311, a memory 312, an input/output interface 313, a communication interface 314, and the like. Components such as the processor 311 are connected by an internal bus or the like and configured to be able to communicate with each other.

However, the configuration shown in FIG. 23 is not intended to limit the hardware configuration of the analysis server 30 . The analysis server 30 may include hardware (not shown), and may not have the input/output interface 313 if necessary. Also, the number of processors 311 and the like included in the analysis server 30 is not limited to the example shown in FIG.

The processor 311 is, for example, a programmable device such as a CPU (Central Processing Unit), MPU (Micro Processing Unit), DSP (Digital Signal Processor). Alternatively, processor 311 may be a device such as FPGA (Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit), or the like. The processor 311 executes various programs including an operating system (OS).

The memory 312 is RAM (Random Access Memory), ROM (Read Only Memory), HDD (Hard Disk Drive), SSD (Solid State Drive), or the like. The memory 312 stores an OS program, application programs, and various data.

The input/output interface 313 is an interface for a display device and an input device (not shown). The display device is, for example, a liquid crystal display. The input device is, for example, a device such as a keyboard or mouse that receives user operations.

The communication interface 314 is a circuit, module, etc. that communicates with other devices. For example, the communication interface 314 includes a NIC (Network Interface Card) or the like.

The functions of the analysis server 30 are realized by various processing modules. The processing module is implemented by the processor 311 executing a program stored in the memory 312, for example. Also, the program can be recorded in a computer-readable storage medium. The storage medium can be non-transitory such as semiconductor memory, hard disk, magnetic recording medium, optical recording medium, and the like. That is, the present invention can also be embodied as a computer program product. Also, the program can be downloaded via a network or updated using a storage medium storing the program. Furthermore, the processing module may be realized by a semiconductor chip.

It should be noted that the exchange server 10 and the authentication server 20 can also be configured by an information processing device in the same way as the analysis server 30, and since their basic hardware configuration is the same as that of the analysis server 30, the explanation will be omitted.

The analysis server 30, which is an information processing device, is equipped with a computer, and the functions of the analysis server 30 can be realized by causing the computer to execute a program. Also, the analysis server 30 executes the information providing method by the program.

[Modification]
The configuration, operation, etc. of the information providing system described in the above embodiment are examples, and are not intended to limit the configuration of the system.

In the above embodiment, the case where information is provided to users via a message-exchange-type SNS has been described. However, the information may be provided by other types of SNS, such as a photo posting type, a message spreading type, a diary type, and the like.

In the above embodiment, it was explained that the user ID used in the communication infrastructure is also used in other infrastructures (biometric authentication infrastructure, data analysis infrastructure). However, if IDs are assigned to users on other platforms, the IDs of the communication platform and the IDs of the other platforms may be linked. Specifically, at the time of user registration, even if the ID of another platform is input to the exchange server 10 and the exchange server 10 notifies the ID of the other platform and the user ID to the authentication server 20 and the analysis server 30 good.

In the above embodiment, the case where information is provided to users who are planning a trip has been explained. However, the target of information provision is not limited to users who are planning a trip. For example, a company employee who needs to commute may be the target of information provision. In this case, the information provision system provides users with useful information for office workers before commuting, useful information for office workers at work, and useful information for office workers after returning home, respectively, to users via the communication infrastructure. You may

In the above embodiment, a case has been described where provision information is generated based on a scenario. However, the provision information may be generated based on other methods and schemes. For example, the analysis server 30 inputs the user's behavior into a learning model obtained by machine learning (AI; Artificial Intelligence), and obtains provided information (information for recommending and guiding the user) from the learning model. good too.

In the above embodiment, it was explained that messages posted by users and results of biometric authentication are used as data for estimating user behavior and situations when providing information. However, other data may be used to estimate the behavior of the user. For example, when the user's location information (the location information of the terminal 40) is obtained via the communication infrastructure, the user's behavior and situation may be estimated based on the location information. The terminal 40 may generate position information based on a GPS (Global Positioning System) signal or the like. Alternatively, the data analysis platform (analysis server 30) may analyze the recipient of the message and its contents, and estimate the behavior of the user. That is, as the first data, analysis may be performed based on location information obtained from GPS or the like, the recipient of the message, and the content of the message (what kind of content was sent to whom).

The user's behavior that triggers the provision of information may be performed at the terminal 40. For example, a scenario such as "If the mail is opened, the tourist spot A will be guided" may be prepared.

The exchange server 10 may confirm the identity of the user when registering the user. Specifically, the exchange server 10 acquires the user's biometric information, personal information, etc., and an identification document (for example, a passport) in which the biometric information is described. The exchange server 10 performs one-to-one matching using the biometric information of the identification document and the biometric information obtained from the user. The exchange server 10 may perform user registration when the collation is successful.

In the above embodiment, we explained the case where positive information such as information on recommended sightseeing spots is provided to the user. However, negative information may be communicated to the user. For example, the user may be provided with information such as amusement park closure information, regular holiday information, and the like.

In the above embodiment, the case where the data analysis platform (analysis server 30) stores the user's personal information and travel information has been described. However, the analysis server 30 does not have to store such information. The analysis server 30 may acquire the information from the biometric authentication infrastructure (authentication server 20) when such information is required. In this case, the analysis server 30 (analysis unit 403) transmits to the authentication server 20 an “information provision request” including the user ID of the user whose personal information or the like is required. The authentication server 20 (authenticated person management unit 302) that has received the information provision request reads the personal information and travel information corresponding to the acquired user ID from the authenticated person information database, and sends the read personal information and the like to the analysis server 30. Send to The authentication server 20 transmits personal information and the like to the analysis server 30 as a response to the information provision request.

In the above embodiment, the case where the feature amount generated from the face image is stored in the authenticated person information database has been described, but the feature amount does not have to be stored in the database. A face image may be registered in the authentication subject information database instead of the feature quantity, and the authentication server 20 may generate the feature quantity from the registered face image each time an authentication request is processed.

In the above embodiment, it was explained that the user inputs travel information into the communication infrastructure (exchange server 10) before traveling. Exchange server 10 may acquire the travel information in the form of a questionnaire. For example, the exchange server 10 may display a questionnaire (pre-trip questionnaire) as shown in FIG. 24 on the terminal 40 of the user. In this case, the user registration unit 202 of the exchange server 10 may display a questionnaire (information input form) as shown in FIG. 24 when the "pre-travel information" button shown in FIG. 9 is pressed.

The user may notify the communication infrastructure (exchange server 10) of the fact that they have arrived at a tourist spot. The exchange server 10 may display on the terminal 40 a questionnaire or the like inquiring about the place where the user arrived, etc., in response to receiving the notification. For example, terminal 40 displays a menu screen as shown in FIG. A user who has arrived at a tourist spot or the like presses an "arrive" button. The terminal 40 transmits a "sightseeing spot arrival notification" to the communication infrastructure (exchange server 10) in response to pressing of the button. Upon receiving the notification, the exchange server 10 displays a questionnaire asking the user where he/she arrived. For example, exchange server 10 displays a questionnaire screen as shown in FIG. The exchange server 10 transmits to the analysis server 30 the information acquired from the questionnaire screen (such as the name of the tourist spot where you arrived). In this way, the analysis server 30 may collect information on the tourist destinations and tourist spots where the user has arrived through questionnaires based on a communication platform.

Alternatively, the user may send impressions during the trip to the communication infrastructure (exchange server 10). For example, the user presses the "Impression" button on the menu screen displayed in FIG. The terminal 40 notifies the communication infrastructure (exchange server 10) that the button has been pressed. The exchange server 10 displays on the terminal 40 a questionnaire screen for the user to input his/her impression in response to the notification. For example, exchange server 10 displays a questionnaire screen as shown in FIG. The exchange server 10 transmits to the analysis server 30 the information (impressions of tourist spots, etc.) acquired from the questionnaire screen. In this way, the analysis server 30 may collect user's impressions of sightseeing spots and sight-seeing spots through questionnaires based on a communication platform.

The data analysis platform (analysis server 30) may acquire the user's wishes when providing information to the user and provide information according to the user's wishes. For example, the analysis server 30 presents the user with a plurality of plans (travel plans) that can be provided via the communication infrastructure. For example, the analysis server 30 presents the user with options such as "family plan for family enjoyment", "solo travel plan for solo enjoyment", and "travel plan not listed in travel magazines". The analysis server 30 may provide information according to the option selected by the user. In this way, when providing information to the user, the analysis server 30 may present a plurality of options to the user and provide information according to the selection result.

The form of data transmission and reception between each device (exchange server 10, authentication server 20, analysis server 30) is not particularly limited, but the data transmitted and received between these devices may be encrypted. Biometric information, photographs, etc. are transmitted and received between these devices, and it is desirable to transmit and receive encrypted data in order to properly protect such information.

In the flowcharts (flowcharts, sequence diagrams) used in the above explanation, multiple steps (processes) are described in order, but the execution order of the steps executed in the embodiment is not limited to the described order. In the embodiment, the order of the illustrated steps can be changed within a range that does not interfere with the content, such as executing each process in parallel.

The above embodiments have been described in detail to facilitate understanding of the disclosure of the present application, and are not intended to require all the configurations described above.
