PROBLEM TO BE SOLVED: To provide a method and system device for authenticating signal sign-on which enable reduction of a system construction cost and an operation managing cost by realizing a single sign-on function without requiring an authentication state managing server for unitarily managing an authentication state. SOLUTION: This characteristic configuration method comprises first authentication processing where a first authentication server 601 to which a contents request (ST31) is applied from an authentication client terminal 501 operated by a user, performs (ST32) the authentication of the user, holds the authentication state as a result of the authentication performance and prepares/issues (ST33) an authentication token showing the authentication state and second authentication processing where a second authentication server 701 to which a contents request (ST41) is applied from the authentication client terminal 501 operated by the user and which accepts the request, performs processing (ST43) concerning the authentication of the user by utilizing (ST44) the authentication token prepared/issued in the first authenticating processing. |
