PROBLEM TO BE SOLVED: To provide a system of providing user attribute information in which a plurality of information processing devices cooperate, capable of keeping secret correspondence between users and an information providing institution holding attribute information on the users and avoiding leakage of the attribute information at a time of performing various processing related to the attribute information on the users.SOLUTION: A providing device 102 selects a device group forming an attribute-information communication path, generates an information registration request in which user information is kept secret in data that only a response partner of each user can recognize, and executes processing for transmitting the information registration request to an access destination solution device 103 via the device group. The access destination solution device 103 stores information on the user indicated by the information registration request and information on the providing device that acts as the response partner in a storage device, receives an inquiry request from an inquiry device 101, and transfers the inquiry request to the providing device that is an inquiry destination by way of the providing devices forming the communication path via the providing device that is the response partner of the user, thereby executing processing for causing the inquiry device 101 to transmit the attribute information on the user by way of the providing devices forming the communication path. |
