Abstract
A digital rights management (DRM) “bureau” server can be used in many different ways. In one example, a system distributes the storage of rights and/or the rights management decision making process between a DRM client and a DRM server, in order to overcome the shortcomings inherent in exclusively client-side or exclusively server-side DRM systems. In another example, a system manages rights to content on behalf of plural publishers.
