PROBLEM TO BE SOLVED: To provide an access control system where it is not necessary for service providers to individually perform access control.;SOLUTION: An access control server which is used in common by a plurality of service providers and devices, is installed and an access permit following a format and a procedure, which the access control server regulates, is issued. Access control is performed in accordance with the access permit and the respective service providers and devices can easily perform access control without constructing self-access control procedures. Since a processing following constant sequence becomes possible without performing access processing sequence corresponding to the individual service providers even in a user device receiving service, it is not necessary to individually store and manage format data and an access program for every device provider.;COPYRIGHT: (C)2002,JPO
