Abstract

A digital rights management method includes: storing information on a rights object in a memory area, wherein the rights object has been transferred from a first device to a second device, and wherein the rights object includes permissions linked to a digital media object; receiving a rights object at the first device; and accessing the memory area to check whether information on the received rights object is stored in the memory area and to set up the received rights object on the first device in case the information on the received rights object is not stored in the memory area, and to reject the received rights object in case the information on the received rights object is stored in the memory area.
