ABSTRACT:
In order to allow for security beyond revocation lists, a policy regarding when permissions may be granted (in the form of a rights document, e.g. a use license or a certificate) is enforced. When a request is made for a rights document, the requester submits an account certificate which includes certain metadata regarding the requester. This metadata is analyzed to determine whether it meets a specific policy before the request is granted. If the request is not granted, the cause of the rejection may be overcome, for example by updating or upgrading some system component (hardware or software) in the requesting system. In certain cases, such an update to overcome a policy-based rejection may be performed transparently to the user.
