[0009] Hereinafter, the information processing device, the information processing method, and the information processing program according to the present application will be described in detail with reference to the drawings. Note that the information processing device, the information processing method, and the information processing program according to the present application are not limited to the embodiments. In addition, the same components in the following embodiments are denoted by the same reference numerals, and duplicated descriptions are omitted.

[0010] [1. Overview of the information processing system] First, an overview of an information processing system according to an embodiment will be described with reference to Fig. 1. Fig. 1 is an explanatory diagram showing an overview of an information processing system according to an embodiment. Note that Fig. 1 describes an example in which authentication is introduced at an appropriate timing into the life cycle of a certificate to form new trust.

[0011] 1, the information processing system 1 includes a terminal device 10 and a server device 100. The terminal device 10 and the server device 100 are connected to each other via a network N (see FIG. 3) in a wired or wireless manner so as to be able to communicate with each other. In this embodiment, the terminal device 10 cooperates with the server device 100.

[0012] The terminal device 10 is a smart device such as a smartphone or tablet terminal used by a user U (user) or the like, and is a mobile terminal device that can communicate with any server device via a wireless communication network such as 5G (Generation) or LTE (Long Term Evolution). The terminal device 10 has a screen such as a liquid crystal display having a touch panel function, and accepts various operations on display data such as content, such as tapping, sliding, scrolling, etc., performed by a finger or a stylus from the user U. An operation performed on an area of ​​the screen where the content is displayed may be considered as an operation on the content. The terminal device 10 may be not only a smart device, but also an information processing device such as a desktop PC (Personal Computer) or a notebook PC.

[0013] The server device 100 is an information processing device that cooperates with the terminal device 10 of the user U and provides the terminal device 10 of the user U with API (Application Programming Interface) services for various applications (hereinafter, apps), etc., as well as various data, and is realized by a computer, a cloud system, etc.

[0014] The server device 100 may also be an information processing device that provides some kind of online Web service to the terminal device 10 of the user U. For example, the server device 100 may provide services such as Internet connection, search service, SNS (Social Networking Service), electronic commerce (EC), electronic payment, online games, online banking, online trading, hotel and ticket reservations, video and music distribution, news, maps, route search, route guidance, line information, operation information, and weather forecasts as Web services. In practice, the server device 100 may cooperate with various servers that provide the above-mentioned Web services, and may mediate the Web services or be responsible for processing the Web services.

[0015] The server device 100 can acquire user information about the user U. For example, the server device 100 acquires information about the attributes of the user U, such as the gender, age, and residential area of ​​the user U. The server device 100 then stores and manages the information about the attributes of the user U together with identification information (such as a user ID) indicating the user U.

[0016] The server device 100 also acquires various types of history information (log data) indicating the actions of the user U from the terminal device 10 of the user U or from various servers based on the user ID or the like. For example, the server device 100 acquires a location history, which is a history of the location and date and time of the user U, from the terminal device 10. The server device 100 also acquires a search history, which is a history of search queries input by the user U, from a search server (search engine). The server device 100 also acquires a browsing history, which is a history of content browsed by the user U, from a content server. The server device 100 also acquires a purchase history (payment history), which is a history of product purchases and payment processing by the user U, from an electronic commerce server or a payment processing server. The server device 100 may also acquire a listing history, which is a history of listings on the marketplace by the user U, and a sales history, from the electronic commerce server or the payment processing server. The server device 100 also acquires a posting history, which is a history of posts by the user U, from a posting server that provides a word-of-mouth posting service or an SNS server. The above-mentioned various servers and the like may be the server device 100 itself. That is, the server device 100 may function as the above-mentioned various servers and the like.

[0017] In this embodiment, for convenience, the terminal device 10 used by the user U who is the subject is referred to as the "user terminal 10-U". Also, the terminal device 10 used by the user U who is the certifier is referred to as the "certifier terminal 10-C", and among the certifier terminals 10-C, the terminal device 10 used by the certifier A is referred to as the "certifier terminal 10-A", and the terminal device 10 used by the observer B is referred to as the "observer terminal 10-B". Also, the terminal device 10 used by the user U or a business operator who is a verifier (hereinafter referred to as the "verifier V") is referred to as the "verifier terminal 10-V". Also, the server device 100 of the issuer is referred to as the "issuer device 100-I".

[0018] The verifier terminal 10-V may be a server device similar to the issuer device 100-I (the issuer's server device 100). That is, the verifier terminal 10-V may be the verifier device 100-V. Also, the server device 100 linked to the verifier terminal 10-V via an API or the like may be the verifier device 100-V. The same applies to the prover terminal 10-C (the certifier terminal 10-A and the observer terminal 10-B).

[0019] [1-1. Approval confirmation device] In existing information verification systems, user U can receive various services by submitting a certificate. However, before user U can submit the certificate, preparations are required. For example, a vaccination certification app requires preparation of a My Number. Also, a system is required for verifier V to perform verification, but in reality, the flow is often limited to visual confirmation.

[0020] Therefore, in this embodiment, authentication is introduced at an appropriate timing in the life cycle of the certificate, and new trust is formed.

[0021] For example, as shown in FIG. 1, user U requests a certifier (certifier A or observer B) to attest to user U's actions, abilities, results, etc. (step S1). For example, when user U succeeds in an eating challenge at a certain restaurant, he or she requests observer B (other customers or spectators at the venue, etc.) or certifier A (store staff, judges, etc.) to attest to the success of the eating challenge. Note that certifier A may be a qualified person who can confirm / verify certain facts. The subject of the certification may also be the presence or absence of technical level, skill, or ability, the number of wins and winning rate in unofficial matches, the skill in online / offline games, user U's past logs, etc.

[0022] At this time, the user terminal 10-U transmits a request (demand) for certification regarding the actions, abilities, achievements, etc. of user U to the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) in response to user U's operation (input, selection, button press, etc.). If the certifier A is a clerk or employee of a store, etc., the certifier terminal 10-A may be a store terminal, a POS register, a handheld terminal, etc. In practice, user U may verbally request certification regarding user U's actions, abilities, achievements, etc. from the certifier (certifier A or observer B).

[0023] Next, in response to a request for certification from user U, the verifier (certifier A or observer B) requests an issuer (certified business operator) IS to issue a certificate (certification) regarding the actions, capabilities, achievements, etc. of user U (step S2). At this time, the verifier (certifier A or observer B) uses the issuer's system to input the contents of the certificate (subject of certification) that he / she wishes to issue.

[0024] At this time, the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) sends a request (demand) for the issuance of a certificate regarding user U's actions, abilities, achievements, etc., along with the contents entered by the certifier (certifier A or observer B) to the issuer device 100-I.

[0025] Next, in response to a request for issuance of a certificate from the certifier (certifier A or observer B), the issuer device 100-I performs identity authentication of the certifier (certifier A or observer B) as evidence of the behavior, ability, achievements, etc. of user U (step S3). In other words, the issuer device 100-I performs identity authentication of the person who observed the behavior, ability, achievements, etc. of user U. The certifier (certifier A or observer B) is authenticated using his / her own account. This identity authentication may be FIDO authentication. Note that in practice, the certifier (certifier A or observer B) may log in to the issuer's system using his / her own account and then input the contents of the certificate he / she wishes to issue.

[0026] At this time, the issuer device 100-I verifies the observer B and the certifier A on behalf of the verifier V. The issuer device 100-I also verifies facts using attribute information of the observer B and the certifier A. Then, the issuer device 100-I helps the observer B and the certifier A to issue a certificate to the user U based on the verified facts.

[0027] For example, the issuer device 100-I verifies that the certifier A is a store clerk or an official certifier from the attribute information of the certifier A. The issuer device 100-I also verifies that the observer B's location information and location history is a person who witnessed the actions, abilities, achievements, etc. of the user U at the same time and place (such as in the store) or witnessed the actions, abilities, achievements, etc. of the user U. Furthermore, the issuer device 100-I may verify from the attribute information and history information of the observer B that the observer B is not a person who has a close relationship with the user U, such as a family member, relative, or friend of the user U, or a person who has some kind of interest in the user U.

[0028] Next, if the issuer device 100-I succeeds in authenticating the certifier (certifier A or observer B), it issues a certificate to the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) (step S4). That is, the issuer device 100-I creates a certificate on behalf of the certifier, observer B or certifier A. By acting as the certifier, it is possible to form trust of the certificate without leaving behind personal information (such as personal name) of observer B or certifier A.

[0029] Next, when the certifier (certifier A or observer B) receives the certificate from the issuer, it provides the certificate to user U as the certifier (step S5). For example, when the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) receives the certificate from issuer device 100-I, it provides the certificate to user terminal 10-U.

[0030] In addition, the issuer may be a certifier, not limited to the certifier (certifier A or observer B). For example, the issuer may be a certifier (certifier A or observer B). In other words, the issuer may be included in the certifier.

[0031] Next, the user terminal 10-U presents the certificate to the verifier terminal 10-V (step S6). The method (means) for presenting the certificate may be via a network, near field communication (NFC), or reading a QR code (registered trademark) or a two-dimensional barcode. An appropriate method may be selected depending on the situation and purpose. The contents of the presented certificate may include the date and time of issue (date and time of creation) of the certificate, the number of certifiers, etc. The number of certifiers may be indicated for each type of certifier.

[0032] The verifier terminal 10-V may request FIDO authentication from the user terminal 10-U when (or before) receiving the certificate. In response to the request, the user terminal 10-U performs identity authentication of the user U.

[0033] For example, FIDO authentication can implement authentication methods using stored or owned items such as PIN (Personal Identification Number), USB (Universal Serial Bus) security key, and smart card, as well as authentication methods using biometric information and behavioral information such as fingerprints, faces, irises, veins, and voiceprints. Authentication methods are not limited to these, and any method can be implemented. In addition, multiple authentication methods can be combined to realize multimodal biometric authentication or multifactor authentication.

[0034] In addition, the user terminal 10-U may pass the certificates together to the verifier terminal 10-V. For example, the user terminal 10-U may pass to the verifier terminal 10-V a certificate list including multiple certificates that may be passed to the verifier V.

[0035] Next, the verifier V provides a service to the user U in response to the presentation of the certificate (step S7). The provision of a service may be the provision of goods, benefits, or incentives, the provision or disclosure of some information or data, or the granting of some rights, qualifications, or permissions. Furthermore, the verifier V may grant the user U the rights, qualifications, or permissions to receive the service in response to the presentation of the certificate. At this time, the verifier terminal 10-V may set the above rights, qualifications, and permissions in response to the operation of the verifier V (or automatically), or may provide information regarding the above rights, qualifications, and permissions to the user terminal 10-U.

[0036] [1-2. UX improvement plan] A UX (user experience) improvement plan in this embodiment will be described with reference to Fig. 2. Fig. 2 is an explanatory diagram showing an overview of a UX improvement plan according to the embodiment.

[0037] 2, for example, the user U uses the user terminal 10-U to preset a certificate provision policy regarding the provision of certificates to external parties in the issuer service provided by the issuer device 100-I (step S11). That is, the user U presets the certificates (seals) that may be handed over to the verifier V.

[0038] For example, the user U may use the user terminal 10-U to set in advance for the issuer device 100-I "certificates that may be provided" or "certificates that may not be provided" or "granularity that may be provided" for each category of verifiers (or each verifier). The issuer device 100-I determines whether or not to provide the certificates based on this setting.

[0039] At this time, the user U may use the user terminal 10-U to register the user ID and a means of personal identification (such as a FIDO authentication authenticator or public key) in advance with the issuer's service. Also, when the issuer device 100-I issues a certificate (seal), it may register it in association with the user ID. At this time, the user terminal 10-U may be registered with the issuer device 100-I via the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B).

[0040] Next, the verifier terminal 10-V uses a camera function to take a picture of the user U requesting the provision of the service (step S12). At this time, the verifier terminal 10-V may identify the user U (and his / her user ID) by facial image recognition of the user U. The verifier terminal 10-V may also request the user terminal 10-U to authenticate the user.

[0041] Next, the verifier terminal 10-V receives the user ID provided from the user terminal 10-U (step S13). For example, the verifier terminal 10-V may request the user ID from the user terminal 10-U and receive the user ID as a response to the request. Alternatively, the verifier terminal 10-V may receive the user ID from the user terminal 10-U as a result of authenticating the user U.

[0042] Next, the verifier terminal 10-V transmits the user ID to the issuer device 100-I to request a certificate for user U (step S14). The verifier terminal 10-V may notify the issuer device 100-I of the type of certificate requested by the verifier V together with the user ID.

[0043] Next, the issuer device 100-I selects a certificate that can be provided to the verifier V from among the certificates linked to the user ID in accordance with a certificate provision policy preset by the user U (step S15). Note that the issuer device 100-I can also select a certificate that can be provided to the verifier V from among the certificates linked to the user ID in accordance with not only the certificate provision policy preset by the user U but also a certificate provision policy specified by the issuer. In other words, the issuer device 100-I may select a certificate that complies with the certificate provision policies of both the user U and the issuer.

[0044] Next, the issuer device 100-I creates a certificate list by collecting the selected certificates (step S16). That is, the issuer device 100-I may pass the certificate list, which collects multiple certificates, to the verifier terminal 10-V.

[0045] The certificate list provided by the certifier may include all certificates issued to the user U, or may include only certificates selected by the user U. For example, it is determined in advance which certificates should be used by the verifier V.

[0046] Alternatively, issuer device 100-I may have the certifier issue different certificates depending on the category (type) or attributes of verifier V. For example, if the category of verifier V is a restaurant, the certifier may hand over only certificates related to restaurants to verifier V.

[0047] Alternatively, the verifier terminal 10-V may select a certificate when the user U (the person himself / herself) consents to the provision of the certificate. At this time, the verifier terminal 10-V may ask the user U (directly or via the user terminal 10-U) by voice (or by displaying on a screen) a question such as "Are you a competitive eating champion?", and may determine consent when the user responds "Yes, I am," select a certificate corresponding to the content, and request (demand) the provision of the certificate from the issuer device 100-I.

[0048] Furthermore, the issuer device 100-I may provide the certificate to the verifier V only when consent is obtained from the user U. When the issuer device 100-I receives a request (demand) from the verifier terminal 10-V to provide the certificate, it may inquire of the user terminal 10-U whether it is OK to provide the certificate, and provide the certificate only when OK is received. At this time, the issuer device 100-I may request the user terminal 10-U to authenticate the user U along with an inquiry as to whether provision of the certificate is permitted, and provide the certificate only when the authentication is successful and permission (consent) to provide the certificate is obtained. This authentication may be FIDO authentication.

[0049] Next, the issuer device 100-I provides the certificate list to the verifier terminal 10-V (step S17).

[0050] Next, the verifier terminal 10-V uses a camera function to display the contents of the certificates included in the certificate list in augmented reality (AR) near an image (such as the face) of the user U on a screen showing the user U (step S18). Through this augmented reality, the verifier confirms that the issuer device 100-I has given the stamp of approval that the user U is a "big eater champion" or "XXX master." The displayed certificate contents may include the certificate issue date and time (creation date and time), the number of certifiers, etc. The number of certifiers may be shown for each type of certifier.

[0051] Furthermore, if the certificate is used as reservation information rather than simply as a seal of approval, it can take the place of a ticket. In other words, the certificate is used as a certificate related to the reservation of user U, rather than a certificate related to the actions, abilities, results, etc. of user U. For example, the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) receives a request for reservation certification from user U and requests the issuer device 100-I to issue a certificate related to user U's reservation. The issuer device 100-I issues a certificate related to user U's reservation and passes it to the certifier terminal 10-C. The certifier terminal 10-C passes the certificate related to user U's reservation to the user terminal 10-U. The user terminal 10-U presents the certificate related to user U's reservation to the verifier terminal 10-V. The verifier terminal 10-V delivers the reserved product, or checks in or allows entry to the venue, depending on the certificate related to user U's reservation.

[0052] [2. Example of information processing system configuration] Next, a configuration of an information processing system 1 including a server device 100 according to an embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of a configuration of the information processing system 1 according to an embodiment. As shown in Fig. 3, the information processing system 1 according to an embodiment includes a terminal device 10 and a server device 100. These various devices are connected to each other via a network N so as to be able to communicate with each other by wire or wirelessly. The network N is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network) such as the Internet.

[0053] Furthermore, the number of devices included in the information processing system 1 shown in Fig. 3 is not limited to that shown in the figure. For example, in Fig. 3, for the sake of simplicity, only one terminal device 10 is shown, but this is merely an example and is not limiting, and two or more devices may be included.

[0054] The terminal device 10 is an information processing device used by a user U. For example, the terminal device 10 is a smart device such as a smartphone or a tablet terminal, a mobile phone such as a feature phone, a personal computer (PC), a personal digital assistant (PDA), a game machine or AV device equipped with a communication function, an information appliance or digital appliance, a car navigation system, a wearable device such as a smart watch or a head-mounted display, smart glasses, etc. The terminal device 10 may also be a house or building, a car, a home appliance, an electronic device, etc. that is compatible with the Internet of Things (IOT).

[0055] In addition, the terminal device 10 can connect to the network N via a wireless communication network such as LTE (Long Term Evolution), 4G (4th Generation), or 5G (5th Generation: 5th generation mobile communication system), or via short-range wireless communication such as Bluetooth (registered trademark) or wireless LAN (Local Area Network), and communicate with the server device 100.

[0056] The server device 100 is, for example, a computer such as a PC or a blade server, or a mainframe or a workstation, etc. The server device 100 may be realized by cloud computing.

[0057] [3. Example of terminal device configuration] Next, the configuration of the terminal device 10 will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of the configuration of the terminal device 10. As shown in Fig. 4, the terminal device 10 includes a communication unit 11, a display unit 12, an input unit 13, a positioning unit 14, a sensor unit 20, a control unit 30 (controller), and a storage unit 40.

[0058] (Communications Department 11) The communication unit 11 is connected to a network N (see FIG. 3) by wire or wirelessly, and transmits and receives information to and from other terminal devices 10 and the server device 100 via the network N. For example, the communication unit 11 is realized by a NIC (Network Interface Card), an antenna, or the like.

[0059] (Display section 12) The display unit 12 is a display device that displays various information such as position information. For example, the display unit 12 is a liquid crystal display (LCD) or an organic electro-luminescent display (OLED). The display unit 12 is a touch panel display, but is not limited to this.

[0060] (Input section 13) The input unit 13 is an input device that accepts various operations from the user U. For example, the input unit 13 has buttons for inputting characters, numbers, and the like. The input unit 13 may be an input / output port (I / O port), a USB (Universal Serial Bus) port, or the like. In addition, when the display unit 12 is a touch panel display, a part of the display unit 12 functions as the input unit 13. In addition, the input unit 13 may be a microphone that accepts voice input from the user U, or the like. The microphone may be wireless.

[0061] (Positioning unit 14) The positioning unit 14 receives a signal (radio wave) transmitted from a satellite of a GPS (Global Positioning System), and acquires position information (e.g., latitude and longitude) indicating the current position of the terminal device 10, which is the device itself, based on the received signal. That is, the positioning unit 14 measures the position of the terminal device 10. Note that the GPS is merely an example of a GNSS (Global Navigation Satellite System).

[0062] The positioning unit 14 can measure the position by various methods other than GPS. For example, the positioning unit 14 may measure the position by using various communication functions of the terminal device 10 as described below as an auxiliary positioning means for position correction or the like.

[0063] (Wi-Fi positioning) For example, the positioning unit 14 uses a Wi-Fi (registered trademark) communication function of the terminal device 10 or a communication network provided by each communication company to measure the position of the terminal device 10. Specifically, the positioning unit 14 performs Wi-Fi communication or the like and measures the distance to a nearby base station or access point to measure the position of the terminal device 10.

[0064] (Beacon positioning) The positioning unit 14 may measure the position by using a Bluetooth (registered trademark) function of the terminal device 10. For example, the positioning unit 14 measures the position of the terminal device 10 by connecting to a beacon transmitter connected by the Bluetooth (registered trademark) function.

[0065] (geomagnetic positioning) The positioning unit 14 also measures the position of the terminal device 10 based on a geomagnetic pattern of a structure measured in advance and a geomagnetic sensor included in the terminal device 10.

[0066] (RFID positioning) Furthermore, for example, if the terminal device 10 has a function of an RFID (Radio Frequency Identification) tag equivalent to a contactless IC card used at station ticket gates, stores, etc., or has a function of reading an RFID tag, the location of use is recorded together with information on a payment or the like made by the terminal device 10. The positioning unit 14 may obtain such information to measure the location of the terminal device 10. Furthermore, the location may be measured by an optical sensor, an infrared sensor, or the like provided in the terminal device 10.

[0067] The positioning unit 14 may, if necessary, measure the position of the terminal device 10 using one or a combination of the above-mentioned positioning means.

[0068] (Sensor unit 20) The sensor unit 20 includes various sensors mounted on or connected to the terminal device 10. The connection may be wired or wireless. For example, the sensors may be detection devices other than the terminal device 10, such as wearable devices and wireless devices. In the example shown in FIG. 4, the sensor unit 20 includes an acceleration sensor 21, a gyro sensor 22, an air pressure sensor 23, a temperature sensor 24, a sound sensor 25, a light sensor 26, a magnetic sensor 27, and an image sensor (camera) 28.

[0069] The above-mentioned sensors 21 to 28 are merely examples and are not intended to be limiting. That is, the sensor unit 20 may be configured to include some of the sensors 21 to 28, or may include other sensors such as a humidity sensor in addition to or instead of the sensors 21 to 28.

[0070] The acceleration sensor 21 is, for example, a three-axis acceleration sensor, and detects physical movements of the terminal device 10, such as the moving direction, speed, and acceleration of the terminal device 10. The gyro sensor 22 detects physical movements of the terminal device 10, such as tilts in three axial directions, based on the angular velocity, etc. of the terminal device 10. The air pressure sensor 23 detects, for example, the air pressure around the terminal device 10.

[0071] Since the terminal device 10 includes the above-mentioned acceleration sensor 21, gyro sensor 22, and air pressure sensor 23, it is possible to measure the position of the terminal device 10 using a technique such as Pedestrian Dead-Reckoning (PDR) that uses these sensors 21 to 23. This makes it possible to obtain indoor position information that is difficult to obtain using a positioning system such as GPS.

[0072] For example, the number of steps, walking speed, and distance walked can be calculated by a pedometer using the acceleration sensor 21. In addition, the moving direction, line of sight direction, and body inclination of the user U can be known by using the gyro sensor 22. In addition, the altitude and floor number on which the terminal device 10 of the user U is located can be known from the air pressure detected by the air pressure sensor 23.

[0073] The air temperature sensor 24 detects, for example, the air temperature around the terminal device 10. The sound sensor 25 detects, for example, the sound around the terminal device 10. The light sensor 26 detects the illuminance around the terminal device 10. The magnetic sensor 27 detects, for example, the geomagnetism around the terminal device 10. The image sensor 28 captures an image around the terminal device 10.

[0074] The above-mentioned air pressure sensor 23, temperature sensor 24, sound sensor 25, light sensor 26, and image sensor 28 can detect the air pressure, temperature, sound, and illuminance, and capture images of the surroundings, thereby detecting the environment and situation around the terminal device 10. In addition, the accuracy of the location information of the terminal device 10 can be improved based on the environment and situation around the terminal device 10.

[0075] (Control unit 30) The control unit 30 includes, for example, a microcomputer having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM, an input / output port, and various other circuits. The control unit 30 may also be configured with hardware such as an integrated circuit, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). The control unit 30 includes a transmitting unit 31, a receiving unit 32, and a processing unit 33.

[0076] (Transmitter 31) The transmission unit 31 can transmit, for example, various information input by the user U using the input unit 13, various information detected by each sensor 21-28 mounted on or connected to the terminal device 10, and location information of the terminal device 10 measured by the positioning unit 14 to other terminal devices 10 or the server device 100 via the communication unit 11.

[0077] (Receiving unit 32) The receiving unit 32 can receive, via the communication unit 11, various types of information provided by other terminal devices 10 and the server device 100, and requests for various types of information from other terminal devices 10 and the server device 100.

[0078] (Processing section 33) The processing unit 33 controls the entire terminal device 10, including the display unit 12, etc. For example, the processing unit 33 can output various information transmitted by the transmission unit 31 and various information received by the reception unit 32 from other terminal devices 10 or the server device 100 to the display unit 12 for display.

[0079] In addition, when the terminal device 10 is used as a terminal device 10 (verifier terminal 10-V) used by a verifier V who verifies a certificate regarding the actions, abilities, and achievements of a user U that has been certified by a certifier and issued by an issuer device 100-I (issuer's server device 100), the processing unit 33 launches a dedicated application, etc., and operates to realize the following functions.

[0080] The photographing unit (image sensor 28) photographs the user U. The accepting unit (input unit 13 or receiving unit 32) accepts user identification information (user ID) indicating the user U from the terminal device 10 (user terminal 10-U) of the user U. The transmitting unit 31 transmits the user identification information to the certificate issuer device 100-I as a request for presentation (submission request) of the certificate.

[0081] At this time, the processing unit 33 functions as a confirmation unit in cooperation with the transmission unit 31 and the reception unit 32, inquiring of the user U regarding actions, abilities, and achievements, and determining that the user U has agreed to the provision of the certificate when a response to the inquiry is received from the user U. Then, when the transmission unit 31 determines that the user U has agreed to the provision of the certificate, it transmits user identification information to the issuer device 100-I.

[0082] The receiving unit 32 receives, as a response to the transmission of the user identification information, from the issuer device 100-I, the certificate linked to the user identification information.

[0083] The receiving unit 32 receives from the issuer device 100-I a certifier list that compiles multiple certificates linked to the user identification information. The receiving unit 32 also receives from the issuer device 100-I, among the certificates linked to the user identification information, a certificate that the user U has permitted to be provided. The receiving unit 32 also receives from the issuer device 100-I, among the certificates linked to the user identification information, a certificate corresponding to the category of the verifier that transmitted the user identification information to the issuer device 100-I.

[0084] The display unit 12 displays the contents of the certificate in augmented reality near the user U within a captured screen showing the user U.

[0085] The processing unit 33 determines to provide a service to the user U according to the contents of the certificate. The processing unit 33 also uses the certificate as reservation information and determines that the user U is the person who made the reservation based on the contents of the certificate regarding the reservation of the user U.

[0086] (Storage unit 40) The storage unit 40 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk drive (HDD), a solid state drive (SSD), an optical disk, etc. Various programs and various data are stored in the storage unit 40.

[0087] [4. Example of Server Device Configuration] Next, a configuration of the server device 100 according to the embodiment will be described with reference to Fig. 5. Fig. 5 is a diagram showing an example of the configuration of the server device 100 according to the embodiment. As shown in Fig. 5, the server device 100 includes a communication unit 110, a storage unit 120, and a control unit 130.

[0088] (Communication unit 110) The communication unit 110 is realized by, for example, a network interface card (NIC), etc. The communication unit 110 is also connected to a network N (see FIG. 3) in a wired or wireless manner.

[0089] (Storage unit 120) The storage unit 120 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a HDD, an SSD, an optical disk, etc. As shown in FIG. 5, the storage unit 120 has a user information database 121, a history information database 122, and a certificate information database 123.

[0090] (User Information Database 121) The user information database 121 stores user information about the user U. For example, the user information database 121 stores various information such as the attributes of the user U. Fig. 6 is a diagram showing an example of the user information database 121. In the example shown in Fig. 6, the user information database 121 has items such as "User ID (Identifier)", "Age", "Gender", "Home", "Workplace", and "Interests".

[0091] The "user ID" indicates identification information for identifying the user U. The "user ID" may be the contact information of the user U (such as a telephone number or an email address), or may be identification information for identifying the terminal device 10 of the user U.

[0092] Furthermore, "age" indicates the age of user U identified by the user ID. Note that "age" may be information indicating the specific age of user U (e.g., 35 years old) or information indicating the generation of user U (e.g., 30s). Alternatively, "age" may be information indicating user U's date of birth or information indicating user U's generation (e.g., born in the 1980s). Furthermore, "gender" indicates the gender of user U identified by the user ID.

[0093] Furthermore, "home" indicates the location information of the home of user U identified by the user ID. In the example shown in Fig. 6, "home" is illustrated as an abstract code such as "LC11", but it may also be latitude and longitude information or the like. Furthermore, for example, "home" may also be a region name or an address.

[0094] Furthermore, "workplace" indicates location information of the workplace (school in the case of a student) of user U identified by the user ID. Note that, in the example shown in Fig. 6, "workplace" is illustrated as an abstract code such as "LC12", but it may also be latitude and longitude information, etc. Furthermore, for example, "workplace" may also be the name of a region or an address.

[0095] Furthermore, "interests" indicate the interests of a user U identified by a user ID. In other words, "interests" indicate subjects in which a user U identified by a user ID is highly interested. For example, "interests" may be search queries (keywords) that a user U inputs into a search engine. Note that, although one "interest" is illustrated for each user U in the example shown in FIG. 6, there may be multiple "interests."

[0096] For example, in the example shown in FIG. 6, the age of user U identified by user ID "U1" is "20s" and the gender is "male." Furthermore, for example, the user U identified by user ID "U1" indicates that his / her home address is "LC11." Furthermore, for example, the user U identified by user ID "U1" indicates that his / her workplace is "LC12." Furthermore, for example, the user U identified by user ID "U1" indicates that he / she is interested in "sports."

[0097] Here, in the example shown in Figure 6, abstract values ​​such as "U1", "LC11", and "LC12" are used to illustrate the data, but "U1", "LC11", and "LC12" are assumed to store information such as specific character strings and numerical values. In the following figures relating to other information, abstract values ​​may also be illustrated.

[0098] The user information database 121 may store various information according to the purpose, not limited to the above. For example, the user information database 121 may store various information related to the terminal device 10 of the user U. The user information database 121 may also store information related to the attributes of the user U, such as demographic attributes, psychographic attributes, geographic attributes, and behavioral attributes. For example, the user information database 121 may store information such as name, family structure, place of origin (hometown), occupation, job title, income, qualifications, type of residence (detached house, apartment, etc.), whether or not the user has a car, commuting time, commuting route, commuter pass section (station, line, etc.), frequently used station (other than the nearest station to home or workplace), extracurricular activities (location, time zone, etc.), hobbies, interests, and lifestyle.

[0099] (Historical Information Database 122) The history information database 122 stores various information related to history information (log data) indicating the actions, abilities, achievements, etc. of the user U. Fig. 7 is a diagram showing an example of the history information database 122. In the example shown in Fig. 7, the history information database 122 has items such as "user ID", "location history", "search history", "browsing history", "purchase history", and "posting history".

[0100] "User ID" indicates identification information for identifying user U. "Location history" indicates location history, which is a history of user U's location and movements. "Search history" indicates search history, which is a history of search queries entered by user U. "Browse history" indicates browse history, which is a history of content viewed by user U. "Purchase history" indicates purchase history, which is a history of purchases made by user U. "Post history" indicates posting history, which is a history of posts made by user U. "Post history" may include questions regarding user U's possessions.

[0101] For example, in the example shown in Figure 7, user U identified by user ID "U1" moved as shown in "Location History #1," searched as shown in "Search History #1," viewed content as shown in "Browse History #1," purchased specified products etc. at specified stores etc. as shown in "Purchase History #1," and posted as shown in "Post History #1."

[0102] Here, in the example shown in Figure 7, abstract values ​​such as "U1," "Location History #1," "Search History #1," "Browse History #1," "Purchase History #1," and "Post History #1" are used for the illustration, however, specific information such as character strings and numbers is stored in "U1," "Location History #1," "Search History #1," "Browse History #1," "Purchase History #1," and "Post History #1."

[0103] The history information database 122 may store various information according to the purpose, without being limited to the above. For example, the history information database 122 may store the usage history of a specific service by the user U. The history information database 122 may also store the history of the user U's visit to a physical store or the history of the user U's visit to a facility. The history information database 122 may also store the payment history of the user U's payment (electronic payment) using the terminal device 10.

[0104] (Certificate Information Database 123) The certificate information database 123 stores various information related to certificates that certify the actions, capabilities, achievements, etc. of the user U. Fig. 8 is a diagram showing an example of the certificate information database 123. In the example shown in Fig. 8, the certificate information database 123 has items such as "user ID", "certificate ID", "certification subject", "certifier", and "provision policy".

[0105] "User ID" indicates identification information for identifying user U. Furthermore, "certificate ID" indicates identification information for identifying the certificate that certifies the behavior, ability, achievements, etc. of user U. Furthermore, "subject of certification" is the content of the certificate, and indicates the behavior, ability, achievements, etc. of user U that are the subject of certification. Furthermore, "provider" indicates identification information for identifying the certifier who observed and confirmed the behavior, ability, achievements, etc. of user U. Note that there may be multiple certifiers. Furthermore, "provision policy" indicates the certificate provision policy that is set in advance by user U. For example, the certificate provision policy indicates the conditions (presentation conditions) regarding the party (verifier) ​​to which the certificate may be presented.

[0106] For example, in the example shown in Figure 7, the certificate with certificate ID "Certificate #1" issued to user U identified by user ID "U1" certifies the actions, abilities, achievements, etc. of user U indicated by "Certification Subject #1," has been confirmed by a certifier identified by "Prover #1," and can be presented to a verifier that conforms to "Provision Policy #1."

[0107] Here, in the example shown in Figure 8, abstract values ​​such as "U1", "Certificate #1", "Subject to Certification #1", "Prover #1", and "Provision Policy #1" are used for the illustration, however, specific information such as character strings and numerical values ​​is assumed to be stored in "U1", "Certificate #1", "Subject to Certification #1", "Prover #1", and "Provision Policy #1".

[0108] Note that certificate information database 123 is not limited to the above and may store various kinds of information depending on the purpose. For example, certificate information database 123 may store identification information for identifying an issuer that issued a certificate. Certificate information database 123 may also store the issuance date and time of a certificate, the expiration date of a certificate, etc. Certificate information database 123 may also store information related to the credibility of a certifier, etc.

[0109] (Control unit 130) Returning to Fig. 5, the description will be continued. The control unit 130 is a controller, and is realized by, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like, executing various programs (corresponding to an example of an information processing program) stored in a storage device inside the server device 100 using a storage area such as a RAM as a working area. In the example shown in Fig. 5, the control unit 130 has an acquisition unit 131, an issuance request acceptance unit 132, a verification unit 133, an issuance unit 134, a setting registration unit 135, a determination unit 136, and a provision unit 137.

[0110] (Acquisition part 131) The acquisition unit 131 acquires a search query input by a user U (user). For example, when the user U inputs a search query into a search engine or the like to perform a keyword search, the acquisition unit 131 acquires the search query via the communication unit 110. That is, the acquisition unit 131 acquires, via the communication unit 110, a keyword input by the user U into a search box of a search engine, a site, or an app.

[0111] Furthermore, the acquisition unit 131 acquires user information regarding the user U via the communication unit 110. For example, the acquisition unit 131 acquires identification information (such as a user ID) indicating the user U, location information of the user U, attribute information of the user U, and the like from the terminal device 10 of the user U. Furthermore, the acquisition unit 131 may acquire identification information indicating the user U, attribute information of the user U, and the like when registering the user U. Then, the acquisition unit 131 registers the user information in the user information database 121 of the storage unit 120.

[0112] Furthermore, the acquisition unit 131 acquires various types of history information (log data) indicating the actions, abilities, achievements, etc. of the user U via the communication unit 110. For example, the acquisition unit 131 acquires various types of history information indicating the actions, abilities, achievements, etc. of the user U from the terminal device 10 of the user U, or from various servers, etc. based on the user ID, etc. Then, the acquisition unit 131 registers the various types of history information in the history information database 122 of the storage unit 120.

[0113] (Issue request reception unit 132) The issuance request receiving unit 132 receives a request for issuance of a certificate together with input of the content of the proof regarding the behavior, ability, and achievements of the user U from the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) that has been requested by the user U to provide proof regarding the behavior, ability, and achievements of the user U. The issuance request receiving unit 132 may be the acquisition unit 131 described above.

[0114] (Verification Section 133) The verification unit 133 verifies the certifier (certifier A or observer B) when it receives a request for issuing a certificate. For example, in response to a request for issuing a certificate from the certifier, the verification unit 133 performs identity authentication of the certifier (certifier A or observer B) as evidence of the behavior, ability, achievements, etc. of user U. In other words, the verification unit 133 performs identity authentication of the person who observed the behavior, ability, achievements, etc. of user U.

[0115] (Issued by 134) When the issuing unit 134 determines that the certifier is valid through verification of the certifier, it issues to the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) a certificate regarding the actions, capabilities, and achievements of the user U, which can be provided to the user U. The issuing unit 134 may also create a certificate list that compiles multiple certificates.

[0116] (Settings registration unit 135) The setting registration unit 135 accepts and registers a certificate provision policy from the user terminal 10-U via the communication unit 110. For example, the setting registration unit 135 associates user identification information indicating the user U with the certificate provision policy, registers the associated information, and manages the associated information internally (or online).

[0117] (Judgment unit 136) The determination unit 136 selects a certificate that can be provided to the verifier V from among the certificates linked to the user ID in accordance with a certificate provision policy preset by the user U (step S112).

[0118] (Providing Department 137) The providing unit 137 provides the certificate to the verifier terminal 10-V via the communication unit 110. The providing unit 137 may provide a certificate list that compiles a plurality of certificates.

[0119] 5. Processing Procedure Next, a processing procedure by the server device 100 according to the embodiment will be described with reference to Fig. 9. Fig. 9 is a sequence diagram showing the processing procedure according to the embodiment. Note that the processing procedure shown below is repeatedly executed by the control unit 30 of the terminal device 10 and the control unit 130 of the server device 100.

[0120] For example, as shown in FIG. 9, the transmission unit 31 of the user terminal 10-U transmits a request (demand) for certification regarding the user U's actions, abilities, achievements, etc. to the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) in response to the user U's operation on the input unit 13 (step S101).

[0121] Next, the transmission unit 31 of the certifier terminal 10-C transmits a request (demand) for issuance of a certificate regarding user U's behavior, abilities, achievements, etc., to the issuer device 100-I, along with the contents input by the certifier (certifier A or observer B) via the input unit 13 (step S102).

[0122] Next, when the issuance request receiving unit 132 receives a request for issuance of a certificate from the certifier terminal 10-C, the verification unit 133 of the issuer device 100-I performs identity authentication of the person who observed the behavior, ability, achievement, etc. of the user U (step S103). At this time, the issuer device 100-I verifies the facts using the attribute information of the observer B and the certifier A.

[0123] Next, if the issuing unit 134 of the issuer device 100-I succeeds in authenticating the certifier (certifier A or observer B), it issues a certificate to the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) (step S104). The issuing unit 134 may create a certificate list that compiles multiple certificates.

[0124] Next, when the receiver 32 of the certifier terminal 10-C receives the certificate from the issuer device 100-I, the transmitter 31 of the certifier terminal 10-C provides the certificate to the user terminal 10-U (step S106).

[0125] In addition, if user terminal 10-U does not present the certificate directly to verifier terminal 10-V, the certifier terminal 10-C may not provide the certificate to user terminal 10-U. In this case, issuer device 100-I may not provide the issued certificate to certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B), but may link the user identification information (user ID) indicating user U with the certificate, register it, and manage it internally (or online). Below, a case will be described in which user terminal 10-U does not present the certificate directly to verifier terminal 10-V.

[0126] The processing unit 33 of the user terminal 10-U sets, via the communication unit 11, the certificate provision policy input in advance by the user U via the input unit 13 for the issuer device 100-I (step S107).

[0127] Next, the setting registration unit 135 of the issuer device 100-I accepts and registers the certificate provision policy from the user terminal 10-U via the communication unit 110 (step S108). For example, the setting registration unit 135 associates the user identification information indicating the user U with the certificate provision policy, registers it, and manages it internally (or online).

[0128] Next, the processing unit 33 of the verifier terminal 10-V uses the camera function of the photographing unit (image sensor 28) or the like to photograph the user U (step S108).

[0129] Next, the processing unit 33 of the verifier terminal 10-V accepts user identification information indicating user U provided from user U's terminal device 10 (user terminal 10-U) via the accepting unit (input unit 13 or receiving unit 32) (step S109).

[0130] The processing unit 33 may request the user identification information from the user terminal 10-U and obtain the user identification information in response. Alternatively, the processing unit 33 may automatically obtain the user identification information from the user terminal 10-U when a photograph of the user U is taken as a trigger. The means for obtaining the user identification information from the user terminal 10-U may be via a network, near field communication (NFC), or reading a QR code (registered trademark), two-dimensional barcode, or the like. The user identification information may be exchanged through communication between dedicated applications installed in the user terminal 10-U and the verifier terminal 10-V.

[0131] Next, when the processing unit 33 of the verifier terminal 10-V receives the user identification information from the user terminal 10-U, it determines that the user U has agreed to the provision of the certificate (step S110).

[0132] Next, if it is determined that the user U has agreed to the provision of the certificate, the transmission unit 31 of the verifier terminal 10-V transmits user identification information to the certificate issuer device 100-I as a request for presentation (submission) of the certificate (step S111).

[0133] Next, the determination unit 136 of the issuer device 100-I selects a certificate that can be provided to the verifier V from among the certificates linked to the user ID in accordance with a certificate provision policy preset by the user U (step S112).

[0134] Next, the providing unit 137 of the issuer device 100-I provides the certificate to the verifier terminal 10-V via the communication unit 110 (step S113). The providing unit 137 may provide a certificate list that compiles multiple certificates.

[0135] Next, the processing unit 33 of the verifier terminal 10-V displays the contents of the certificate in augmented reality (AR) near an image of user U (such as a face) on a screen showing user U using a camera function such as a photographing unit (image sensor 28) (step S114).

[0136] In addition, in the above steps S109 to S114, if the processing unit 33 of the verifier terminal 10-V receives a certificate directly from the user terminal 10-U rather than user identification information, it displays the contents of the certificate received from the user terminal 10-U in augmented reality (AR).

[0137] Next, the processing unit 33 of the verifier terminal 10-V provides a service to the user U according to the contents of the certificate (step S115). The provision of a service may be the provision of an item, benefit, or incentive, the provision or disclosure of some information or data, or the granting of some right, qualification, or permission. For example, the processing unit 33 of the verifier terminal 10-V may grant the user U the right, qualification, or permission to receive the provision of a service according to the contents of the certificate.

[0138] 6. Modifications The above-described terminal device 10 and server device 100 may be implemented in various different forms other than the above-described embodiment. Therefore, the following describes modifications of the embodiment.

[0139] In the above embodiment, some or all of the processing executed by the server device 100 may actually be executed by the terminal device 10. For example, the processing may be completed in a stand-alone manner (by the terminal device 10 alone). In this case, the terminal device 10 is assumed to have the functions of the server device 100 in the above embodiment. Also, in the above embodiment, since the terminal device 10 works in conjunction with the server device 100, from the perspective of the user U, it appears that the processing of the server device 100 is also executed by the terminal device 10. In other words, from another perspective, it can be said that the terminal device 10 is equipped with the server device 100.

[0140] Furthermore, in the above embodiment, the certificate (seal) issued to the user U may be managed on the blockchain (BC) as a non-fungible token (NFT), which is a token existing on the blockchain (BC). That is, the certificate may be NFTed. In this case, the user terminal 10-U accesses and uses the NFTed certificate. For example, instead of providing the certificate, the certifier notifies the user terminal 10-U of the reference destination (DID) of the NFTed certificate. Instead of presenting the certificate, the user terminal 10-U notifies the verifier terminal 10-V of the reference destination (DID) of the NFTed certificate.

[0141] In the above embodiment, the issuer device 100-I may vary the content or value of the certificate depending on the number of certifiers. For example, even if the certificate is for the same action, the more certifiers there are, the higher the credibility of the certificate may be.

[0142] In the above embodiment, the user U and the certifier (certifier A or observer B) may both log in to the issuer's system provided by the issuer device 100-I with their own accounts. For example, the issuer device 100-I transmits a challenge to each of the terminal devices 10 of the user U and the certifier to request FIDO authentication. Each of the terminal devices 10 of the user U and the certifier verifies the identity of the user U or the certifier, respectively, and transmits the verification result (signed challenge) of the identity to the issuer device 100-I. The issuer device 100-I determines whether the identity authentication of the user U and the certifier has been successful or not according to the verification result of the identity. Then, the user U requests the certifier (certifier A or observer B) to certify the actions, abilities, achievements, etc. of the user U. When the issuer device 100-I receives a request from the certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) to issue a certificate regarding the actions, abilities, achievements, etc. of user U, the issuer device 100-I determines whether the certifier is appropriate as a certifier based on the certifier's attribute information, history information, etc., and issues the certificate if it determines that the certifier is appropriate.

[0143] Furthermore, in the above embodiment, the issuer device 100-I may receive input of the contents of the certificate desired to be issued (subject to approval) from the certifier terminal 10-C by voice. At this time, the issuer device 100-I may make a voice inquiry to the certifier terminal 10-C about the contents of the certificate desired to be issued, and when a voice response is received, issue a certificate according to the response. For example, the issuer device 100-I may make a voice inquiry to the certifier terminal 10-C asking "Is this person (user U) a competitive eating champion?", and when the certifier terminal 10-C responds "Yes, that is the case", it may be deemed as consent and an inquiry may be made to the user terminal 10-U as to whether or not to permit the issuance of the certificate.

[0144] In the above embodiment, the issuer device 100-I may update the contents of the certificate. For example, if the user U who is the "big eater champion" becomes the "big eater champion" every year thereafter and remains the "big eater champion" for five consecutive years, the issuer device 100-I may update the contents to "5 consecutive years of big eater champion."

[0145] In the above embodiment, when a new certifier appears who certifies the same contents of a certificate that has already been issued, the issuer device 100-I may update the issue date and time (creation date and time) of the certificate. For example, when the issuer device 100-I receives a request from a new certifier two months ago to issue a certificate that certifies the same contents of a certificate issued five years ago, the issuer device 100-I may update the issue date and time (or certification date and time) of the issued certificate and add the new certifier to the certifiers linked to the certificate.

[0146] 7. Effects As described above, the information processing device (verifier terminal 10-V) of the present application is an information processing device used by a verifier to verify a certificate regarding the actions, abilities, and achievements of user U that has been certified by a certifier and issued by an issuer device 100-I (issuer's server device 100), and is characterized in that it comprises an imaging unit (image sensor 28) that photographs user U, a reception unit (input unit 13, or receiving unit 32) that receives user identification information (user ID) indicating user U from user U's terminal device 10 (user terminal 10-U), a transmission unit 31 that transmits the user identification information to the certificate issuer device, a receiving unit 32 that receives the certificate linked to the user identification information from the issuer device, and a display unit 12 that displays the contents of the certificate in augmented reality near user U within a photographed screen showing user U.

[0147] The receiving unit 32 receives, from the issuer device, a certifier list that compiles a plurality of certificates linked to the user identification information.

[0148] The receiving unit 32 receives, from the issuer device, the certificate that the user U has permitted to be provided, from among the certificates linked to the user identification information.

[0149] The receiving unit 32 receives, from the issuer device, a certificate corresponding to the category of the verifier that transmitted the user identification information to the issuer device, from among the certificates linked to the user identification information.

[0150] The information processing device (verifier terminal 10-V) according to the present application further includes a confirmation unit (transmission unit 31, reception unit 32, processing unit 33) that inquires of user U regarding actions, abilities, and achievements, and determines that user U has agreed to the provision of the certificate when a response to the inquiry is received from user U. Then, when it is determined that user U has agreed to the provision of the certificate, the transmission unit 31 transmits user identification information to the issuer device.

[0151] Moreover, the information processing device (verifier terminal 10-V) according to the present application further includes a processing unit 33 that determines whether to provide a service to the user U depending on the contents of the certificate.

[0152] The processing unit 33 uses the certificate as reservation information and determines that the user U is the person who made the reservation based on the contents of the certificate regarding the user U's reservation.

[0153] In addition, another information processing device (issuer device 100-I) related to the present application is an information processing device used by an issuer that issues certificates regarding the actions, abilities, and achievements of user U, and is characterized in having an issuance request receiving unit 132 that receives a request for issuance of the certificate along with input of the contents of the proof regarding user U's actions, abilities, and achievements from a certifier terminal 10-C (certifier terminal 10-A or observer terminal 10-B) that has been requested by user U to certify user U's actions, abilities, and achievements, a verification unit 133 that verifies the certifier when the request for issuance of the certificate is accepted, and an issuing unit 134 that issues a certificate that can be provided to user U to the certifier terminal 10-C when it is determined that the certifier is valid based on the verification of the certifier.

[0154] By using any one or a combination of the above-mentioned processes, the information processing device according to the present application can appropriately present a certificate regarding the user's actions, capabilities, and achievements.

[0155] [8. Hardware Configuration] Moreover, the terminal device 10 and the server device 100 according to the above-described embodiment are realized by a computer 1000 having a configuration as shown in Fig. 10, for example. The server device 100 will be described below as an example. Fig. 10 is a diagram showing an example of a hardware configuration. The computer 1000 is connected to an output device 1010 and an input device 1020, and has a configuration in which a calculation device 1030, a primary storage device 1040, a secondary storage device 1050, an output I / F (Interface) 1060, an input I / F 1070, and a network I / F 1080 are connected by a bus 1090.

[0156] The arithmetic device 1030 operates based on programs stored in the primary storage device 1040 and the secondary storage device 1050, programs read from the input device 1020, and the like, and executes various processes. The arithmetic device 1030 is realized by, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like.

[0157] The primary storage device 1040 is a memory device such as a RAM (Random Access Memory) that primarily stores data used by the arithmetic device 1030 for various calculations. The secondary storage device 1050 is a storage device in which data used by the arithmetic device 1030 for various calculations and various databases are registered, and is realized by a ROM (Read Only Memory), an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flash memory, or the like. The secondary storage device 1050 may be an internal storage device or an external storage device. The secondary storage device 1050 may be a removable storage medium such as a USB (Universal Serial Bus) memory or an SD (Secure Digital) memory card. The secondary storage device 1050 may be a cloud storage (online storage), a NAS (Network Attached Storage), a file server, or the like.

[0158] The output I / F 1060 is an interface for transmitting information to be output to an output device 1010 that outputs various types of information, such as a display, a projector, a printer, etc., and is realized by a connector conforming to a standard such as USB (Universal Serial Bus), DVI (Digital Visual Interface), or HDMI (registered trademark) (High Definition Multimedia Interface). The input I / F 1070 is an interface for receiving information from various input devices 1020, such as a mouse, a keyboard, a keypad, a button, a scanner, etc., and is realized by a USB, etc.

[0159] Furthermore, the output I / F 1060 and the input I / F 1070 may be wirelessly connected to the output device 1010 and the input device 1020, respectively. That is, the output device 1010 and the input device 1020 may be wireless devices.

[0160] The output device 1010 and the input device 1020 may be integrated into one device, such as a touch panel. In this case, the output I / F 1060 and the input I / F 1070 may also be integrated into one device, such as an input / output I / F.

[0161] The input device 1020 may be a device that reads information from, for example, an optical recording medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), or a PD (Phase change rewritable Disk), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory.

[0162] The network I / F 1080 receives data from other devices via the network N and sends it to the arithmetic device 1030, and also transmits data generated by the arithmetic device 1030 to other devices via the network N.

[0163] The arithmetic unit 1030 controls the output device 1010 and the input device 1020 via the output I / F 1060 and the input I / F 1070. For example, the arithmetic unit 1030 loads a program from the input device 1020 or the secondary storage device 1050 onto the primary storage device 1040 and executes the loaded program.

[0164] For example, when the computer 1000 functions as the server device 100, the arithmetic unit 1030 of the computer 1000 executes a program loaded onto the primary storage device 1040 to realize the functions of the control unit 130. The arithmetic unit 1030 of the computer 1000 may also load a program acquired from another device via the network I / F 1080 onto the primary storage device 1040 and execute the loaded program. The arithmetic unit 1030 of the computer 1000 may also cooperate with the other device via the network I / F 1080 and use functions and data of a program by calling them from another program of the other device.
