The terminal 1, in transmitting a request to the WWW server 3, transmits the authentication information. The WWW server 3 has an authentication collaborative processing means 34 that extracts the user information and the time information from the authentication information and performs the collaborative processing of authentication, and a means 31 that, if the correctness of the authentication information is verified and the user is authenticated, accepts the user's request and transmits the request result together with the newly generated authentication information to the terminal. |
