摘要
A message, method and system for processing rights object (RO) in a DRM system are disclosed. A message for requesting submission or return of an unused/partially consumed rights object (RO) is newly defined. When an authenticated device generates such a request message and transmits it to a right issuer (RI), the RI checks whether there exists an ID of a receiving device in the request message. If an ID of a receiving device exists in the request message, the RI performs a procedure for submitting the RO to the ID of the receiving device. If, however, the ID of the receiving device does not exist, the RI performs a procedure of returning of the RO or issuing of a different RO. Accordingly, the unused RO or partially consumed RO can be returned or submitted to a different device by using the request message.
