摘要

PURPOSE: A service verifying system, an authentication request terminal, a service use terminal and a service supplying method are provided to verify a use permission message to use a service with regards to a service use terminal, thereby reducing a cost without installing a new authenticator by using authenticated results. CONSTITUTION: An authentication information DB(11) receives user authentication information. A usable service information DB(12) receives information on usable services. A use permission message state DB(13) receives message state information of a use permission message. An authenticator(16) specifies a user of an authentication request terminal(30) by using a message received from the terminal(30), and authenticates whether the user can use a service(A). An other service use deciding unit(17) decides whether the user can use other service when receiving a use request about the other service. A use permission message state updating unit(18) updates the use permission message state DB(13). A service supply deciding unit(19) decides whether a service(B) can be supplied to a service use terminal(40). A use permission message state canceling unit(20) updates a use permission message state into an unavailable state, if the service is decided to be supplied in the service supply deciding unit(19).
