Information processing device, information processing system, and information processing method

An information processing system comprising:

• a first information processing device of a first user;
• and
• a second information processing device of a second user,
• wherein the second information processing device includes a processor and a memory including at least one of a first information area and a second information area where user information is classified and stored,
• the user information of the second user being classified into either one of the first information area and the second information area on the basis of a level of trust between the second user and the first user who exchanges information with the second user,
• wherein the first information area is a general access permission determination block having a list including a sensitive topic, sensitivity scores assigned to topics including the sensitive topic, and an appropriate data processing level of the user information allowed for the information processing device,
• wherein the second information area is a user-specific access permission block when information is exchanged between the first information processing device and the second information processing device,
• wherein information is exchanged between the first information processing device and the second information processing device when the exchange of the information between the first information processing device and the second information processing device has been allowed, and
• wherein, when information is exchanged between the first information processing device and the second information processing device, the processor acquires first user information about the first user, and
• when processing by the second information processing device is not allowed on the basis of the second information area for processing of the acquired first user information and when transmission to the first information processing device is allowed, the processor does not perform any processing and sends the first user information to the first information processing device after encrypting the first user information, and
• when processing by the second information processing device is not allowed on the basis of the second information area for processing of the acquired first user information and when transmission to the first information processing device is not allowed, the processor does not perform any processing and does not send the first user information to the first information processing device, and
• wherein the processing of the acquired first user information includes at least one of sharing, storing, and learning the acquired first user information by the second information processing device.

An information processing method of an information processing device for processing user information about a user, the information processing method comprising:

• the information processing device including a processor and a memory,
• causing the memory to include at least one of a first information area and a second information area where the user information is classified and stored,
• wherein the first information area is a general access permission determination block having a list including a sensitive topic, sensitivity scores assigned to topics including the sensitive topic, and an appropriate data processing level of the user information allowed for the information processing device,
• wherein the second information area is a user-specific access permission block when information is exchanged between the information processing device and an information processing device of an other user different from the user, and
• causing the processor:
• when information is exchanged between the information processing device and the information processing device of the other user, to acquire other user information about the other user;
• and
• when processing by the information processing device of the user is not allowed on the basis of the second information area for processing of the acquired other user information and when transmission to the information processing device of the other user is allowed,
• not to perform any processing, and
• to send the other user information to the information processing device of the other user after encrypting the other user information;
• and
• when processing by the information processing device of the user is not allowed on the basis of the second information area for processing of the acquired other user information and when transmission to the information processing device of the other user is not allowed,
• not to perform any processing, and
• not to send the other user information to the information processing device of the other user, and
• wherein the processing of the acquired other user information includes at least one of sharing, storing, and learning the acquired other user information by the information processing device of the user.
