PROBLEM TO BE SOLVED: To provide a single sign-on, which has high security strength and is applicable, when a plurality of contents groups exist which are necessary to have different authentications in a single contents server. SOLUTION: The composition has a gateway function, separated from the authentication access control server device of the conventional reverse proxy type, with only an access request in which an entry to permit passing through the gateway device being not set, is transferred to the authentication access control server device, and authentication is made. By adding information discriminating contents of the contents server to a communication permission entry which is set in the gateway server, only the access request to the authenticated contents is permitted to pass, and an access request to contents to which authentication is not permitted, is not permitted to pass through but is transfer to the authentication access control server device.
