Further, for example, the user information is user U1's thermography, user U1's biometric information, and the like. Note that the user information may be information about a plurality of users including the user U1. For example, the user information is an image containing information about multiple users including user U1.

The extraction unit 130 detects users based on the user information. When the user information includes information about multiple users, the extraction unit 130 detects multiple users based on the user information. Thus, the extraction unit 130 detects one or more users based on the user information. Note that when detecting one or more users, the extraction unit 130 can detect the users using a known technique. For example, the extraction unit 130 detects one or more users using Haar-Like features.

The extraction unit 130 extracts the feature amount of the detected user based on the user information. If the user information includes information about multiple users, the extracting unit 130 extracts feature quantities of the multiple detected users based on the user information.

In addition, when extracting the feature amount of one or more users, the extraction unit 130 can extract the feature amount of one or more users using a known technique.

The acquisition unit 140 acquires from the storage unit 110 license request information indicating the content of the license request. For example, the license request information is information that includes at least one of ID, requester, application, and usage information registered in the management table 111 . Here, the license request information may be stored in a device connectable to the information processing device 100 . If the license request information is stored in the device, acquisition unit 140 acquires the license request information from the device via communication unit 120 .

The communication unit 120 transmits license request information to the terminal device 200 . Note that when a plurality of terminal devices including the terminal device 200 exist around the information acquisition device 300, the communication unit 120 simultaneously transmits the license request information to the plurality of terminal devices.

The communication unit 230 of the terminal device 200 receives the license request information. The generation unit 240 generates permission information indicating permission content based on the use permission content information and the use permission request information stored in the storage unit 210 . The permission information may be expressed as information indicating the contents of which the estimation is permitted based on the user information. For example, if the usage permission content information indicates “permit if the usage is personal advertisement” and the usage of the usage permission request information indicates “displaying personal advertisement on signage”, generation unit 240 generates permission information indicating that ID "001" is permitted. In addition, the generation unit 240 generates permission information indicating that the IDs "002" and "003" are not permitted. In addition, the generation unit 240 provides “permission for use by company A”, “permission for age only”, “permission when the purpose is personal advertisement”, and “permission when the information acquisition device 300 is owned by City X”. Permission information indicating “not permitted” may be generated.

Communication unit 230 transmits the feature amount and permission information of user U1 stored in storage unit 210 to information processing apparatus 100 .

The specifying unit 150 specifies an estimation target based on the permission information. For example, if the permission information indicates that the ID "001" is permitted, the identification unit 150 refers to the management table 111 and identifies age, sex, and clothes as estimation targets. Further, for example, when the permission information indicates that “only age is permitted”, the identifying unit 150 identifies age as an estimation target without referring to the management table 111 .

The specifying unit 150 specifies information about the user U1 from among the user information based on the feature amount of one or more users extracted by the extraction unit 130 and the feature amount of the user U1 received by the communication unit 120 . Specifically, the specifying unit 150 specifies the feature amount of the user U1 received by the communication unit 120 from among the feature amounts of one or more users. The identifying unit 150 identifies information about the user U1 corresponding to the identified feature amount of the user U1 from among the user information.

Further, when the feature amounts of a plurality of users are extracted by the extraction unit 130, the specifying unit 150 extracts information about the user U1 from the user information based on the feature amounts of the plurality of users and the feature amount of the user U1. identify. In this way, even when information about a plurality of users is included in the user information, the information processing apparatus 100 can identify the information about the user U1 from the user information based on the feature amount of the user U1.

The estimation generation unit 160 estimates an estimation target based on the information regarding the user U1. For example, the estimation generator 160 estimates the age, gender, and clothes of the user U1. Note that, for example, when the estimation generation unit 160 performs estimation, the estimation generation unit 160 performs estimation using a trained model.

The estimation generation unit 160 generates availability information indicating that the information is available based on the estimation result. In addition, the estimation generation unit 160 may be expressed as generating availability information that is the result of estimation. Note that the usable information is data that can be used within a range agreed upon by the user U1.

If the communication unit 120 has received the desired information, the estimation generating unit 160 may change the estimation result based on the desired information. For example, it is assumed that the estimation result indicates that user U1 is "30 years old". It is assumed that the desired information indicates that the age of user U1 is "28". The estimation generator 160 changes "30 years old" to "28 years old". In this way, the estimation generation unit 160 can change the estimation result to accurate information even when the accuracy of the estimation result may be low.

The communication unit 120 transmits the availability information to the request source based on the destination of the management table 111 . As a result, the requester can use the availability information with peace of mind.
Further, when the communication unit 120 receives an instruction to transmit availability information from the terminal device 200 , the communication unit 120 transmits the availability information to the terminal device 200 . Terminal device 200 receives the availability information. Thereby, the user U1 can check the available information. In addition, user U1 can confirm that the content he has permitted is being used.

The updating unit 170 updates the management table 111. FIG. For example, the updating unit 170 updates the management table 111 by an administrator's operation.

Next, the processing will be described using a specific example. Note that the information acquisition device 300 is assumed to be an imaging device.

Note that the extraction unit 130 detects an area in which one or more users exist, thereby extracting facial image feature amounts of one or more users. Therefore, the identifying unit 150 can identify the area of the user U1 from the image based on the facial image feature amount of the user U1. Also, the information indicated by the area of the user U1 in the image is information about the user U1.

(Step ST108) The estimation generator 160 estimates an estimation target based on the area of the user U1 in the image. For example, the estimation result indicates that the age is 30, the sex is female, and the dress is a red dress.
(Step ST109) The estimation generation section 160 generates availability information based on the estimation result.
(Step ST110) The communication section 120 transmits the available information to the A company based on the transmission destination of the management table 111. FIG.
