摘要:
In a method of enabling Digital Rights Management (DRM) of content in a communications network supporting a DRM system a first user equipment (RMUE), is registering with a first rights issuer of the DRM system from which a delegation assertion, authorizing the RMUE to become a private rights issuer, is retrieved. RMUE retrieves a first, signed rights object from the first rights issuer, that contains a first set of rights for the RMUE to DRM protect private content and to issue at least one second rights object, associated with the private content. DRM protection is then applied on private content, obtained by the RMUE, according to at least the first set of rights. RMUE issues a second rights object, defining a second set of rights for rendering the private content, according to the first set of rights. RMUE may then distribute the second rights object to a second user equipment which is able to render the private content on the basis of at least said second rights object, upon having acquired the private content and the delegate assertion.
