Abstract
A user agent stores a private key and a public key of a user, and user information (registered user information). The user agent receives from a user terminal a service document including identification information of a service provider server and a user information classification requested by the service provider server, and adds a signature to the service document by using the private key of the user. The user terminal receives the signed service document and transmits the signed service document to the service provider server. The user agent receives the signed service document from the service provider server, and verifies the signature and transmits back to the service provider server the user information of the user corresponding to the included user information classification.
