ABSTRACT:
This invention addresses to execute an emergency access interception in a widely distributed environment.An access controller100manages an access control list (ACL)110recording access right to each object, and a black list (BL)120recording user information corresponding to the emergency access interception. The access controller100receives a request for authentication to access right and judges whether or not the access right is proper, first according to the BL120then ACL110. In case where the user information corresponding to the request is recorded in the BL120, the access controller100sends out the user information to other access controllers and instructs them to register it in the black list. This invention effectively actualizes the emergency access interception under the widely distributed environment in case where the interception is required for any user.
