ABSTRACT:
A system and method is provided for identifying electronic devices belonging to the same authenticated user to allow access to shared media even if the electronic devices use incompatible digital rights management (DRM) schemes. By providing a method of registering electronic devices in a centralized rights server database, a user can acquire DRM licenses for the appropriate electronic device by simply registering the electronic devices. When the user later requests a DRM license, it only needs to provide cryptographic proof of a UID, or unique identifier, assigned to the device by the rights server. In this manner, media can he shared across devices Using incompatible DRM schemes.
