Abstract
The present invention provides the ability to compare and enforce policies between trusted entities within a rights management system. For example, policies between the two entities may be received by either entity. They may then be compared to determine the compatibility of the two policies. If compatible, or maybe even without the comparison, other embodiments provide for message server use license, which allows access to the protected portion of a message, thereby permitting an entity to enforce its message policies.
