Patent attributes
An access control request manager based on learning profile based access pathways in a physical access control system (PACS). The access control request manager including an access pathways learning module configured to determine an reachability graph associated with each resource in the PACS, and a permissions request module, the permissions request module including an access request user interface configured to permit a user or an administrator, to provide a request for a permission to permit the user access to, or revoke the user's access to, a resource in the PACS. The permissions request module determines if the requested permission is already granted to the user, computes a pathway to reach the requested resource based on the reachability graph, suggests a permission, if needed, required to satisfy the request based on the computed pathway, and if approved, adds the suggested permission to any permissions granted to the user.
