PROBLEM TO BE SOLVED: To solve the problem that it is necessary to register information for authentication including terminal information in advance under control to connect only a specific terminal to a network service server.SOLUTION: A client terminal transmits connection information including the URL of a network service server to an access control system and an equipment authentication system in the case of requesting service use. An access control system generates equipment authentication information on the basis of connection information from the client terminal when determining that equipment authentication is necessary, and makes an inquiry request to the equipment authentication system, and determines the propriety of connection to the server on the basis of an inquiry result. The equipment authentication system generates equipment authentication information on the basis of connection information from the client terminal, stores the equipment authentication information in an equipment authentication information management DB, inquires whether or not the equipment authentication information whose inquiry request has been made by the access control system is stored in the equipment authentication information management DB, and transmits the inquiry result.SELECTED DRAWING: Figure 1 |
