Abstract

An access permission system includes a collaboration activity information generation unit configured to generate collaboration activity information which is information indicating that a user of an information communication terminal and a user of an information communication terminal collaborated to perform a predetermined activity and a permission unit configured to permit the information communication terminal to access information about the user of the other information communication terminal when the collaboration activity information generated is confirmed.

Claims

1. An access permission system for determining whether to permit access when a first information communication terminal requests access to information about a user of a second information communication terminal, the access permission system comprising:

a collaboration activity information generation unit configured to generate collaboration activity information which is information indicating that a user of the first information communication terminal and the user of the second information communication terminal collaborated to perform a predetermined activity; and

a permission unit configured to permit the first information communication terminal to access the information about the user of the second information communication terminal when the collaboration activity information generated is confirmed.

2. The access permission system according to claim 1,

wherein the collaboration activity information is information including unique information about the user of the first information communication terminal and unique information about the user of the second information communication terminal,

wherein the access permission system comprises an applicant confirmation information generation unit configured to generate applicant confirmation information including the unique information about the user of the first information communication terminal, and

wherein the permission unit permits the first information communication terminal to access information about the user of the second information communication terminal when it is confirmed that part of the collaboration activity information corresponds to the applicant confirmation information.

3. The access permission system according to claim 2,

wherein the unique information is biological information,

wherein the access permission system comprises a biological information extraction unit configured to extract the biological information from the collaboration activity information and the applicant confirmation information, and

wherein the permission unit confirms that the part of the collaboration activity information corresponds to the applicant confirmation information by determining whether there is information similar to the biological information extracted by the biological information extraction unit from the applicant confirmation information among the biological information extracted from the collaboration activity information.

4. The access permission system according to claim 3,

wherein the unique information is face information,

wherein the collaboration activity information is image data in which a face of the user of the first information communication terminal and a face of the user of the second information communication terminal are shown together, and

wherein the applicant confirmation information is image data in which the face of the user of the first information communication terminal is shown.

5. The access permission system according to claim 3,

wherein the unique information is a voice feature quantity,

wherein the collaboration activity information is voice data including a voice of the user of the first information communication terminal and a voice of the user of the second information communication terminal, and

wherein the applicant confirmation information is voice information about the user of the second information communication terminal.

6. The access permission system according to claim 2,

wherein the collaboration activity information is feature quantity information about a contact activity by the user of the first information communication terminal with the user of the second information communication terminal,

wherein the applicant confirmation information is feature quantity information about a contact activity by the user of the second information communication terminal with the user of the first information communication terminal, and

wherein the permission unit confirms whether similarity between the collaboration activity information and the applicant confirmation information is greater than a predetermined threshold value.

7. The access permission system according to claim 1,

wherein the collaboration activity information is predetermined feature quantity information which varies with time,

wherein the access permission system comprises a monitoring unit configured to monitor variation of the feature quantity information, and

wherein the collaboration activity information generation unit extracts subsequent feature quantity information as the collaboration activity information when the monitoring unit detects that the feature quantity information has varied in a predetermined pattern.

8. The access permission system according to claim 1,

wherein the information about the user of the second information communication terminal is recorded in a server device, and

wherein the permission unit is provided in the server device.

9. The access permission system according to claim 8,

wherein the server device includes a possessor confirmation information storage unit configured to store possessor confirmation information including unique information about the user of the second information communication terminal, and

wherein the permission unit permits the first information communication terminal to access information about the user of the second information communication terminal when it is confirmed that part of the collaboration activity information corresponds to the possessor confirmation information.

10. The access permission system according to claim 1, comprising:

a feature quantity extraction unit configured to extract feature quantity information from the collaboration activity information; and

a table configured to associate and store the feature quantity information and a type of information for permitting access,

wherein the permission unit permits access to information about a type associated with the feature quantity information extracted by the feature quantity extraction unit in the table among the information about the user of the second information communication terminal.

11. An access permission determination method of determining whether to permit access when a first information communication terminal requests access to information about a user of a second information communication terminal, the access permission determination method comprising:

a first step of generating, by the second information communication terminal, collaboration activity information which is information indicating that a user of the first information communication terminal and the user of the second information communication terminal collaborated to perform a predetermined activity; and

a second step of permitting, by a device storing the information about the user of the second information communication terminal, the first information communication terminal to access the information about the user of the second information communication terminal when the collaboration activity information generated is confirmed.

12. The access permission determination method according to claim 11,

wherein the collaboration activity information is information including unique information about the user of the first information communication terminal and unique information about the user of the second information communication terminal,

wherein the access permission determination method further comprises a third step of generating, by the first information communication terminal, applicant confirmation information including unique information about the user of the first information communication terminal, and

wherein, in the second step, the device storing the information about the user of the second information communication terminal permits the first information communication terminal to access information about the user of the second information communication terminal when it is confirmed that part of the collaboration activity information corresponds to the possessor confirmation information.
