Abstract
An access control system, which eliminates the necessity for access controls to be performed by individual service providers, has an access control server which is used commonly by a plurality of service providers and devices. The access control server issues access permissions in accordance with predetermined format and procedure. Access control is executed in accordance with the access permission, so that each service provider and each device can easily execute the access control without building up their own access control procedures. A user device which receives the services from various service providers is not required to execute different access control sequences for different service providers, and can execute the access control in accordance with a predetermined sequence. Thus, the user device need not store and administrate different format data and access programs for different service providers.
