Abstract:
1. A digital right management (DRM) device, the device comprising: a memory area that stores information on at least one first rights object that has been moved from the DRM device to another DRM device after which only the another DRM device is capable of exercising rights of the at least one first rights object, wherein the at least one first rights object comprises permissions linked to a digital media object; and a processor programmed or configured to receive a second rights object, wherein the processor is programmed or configured to access the memory area to check whether information on the second rights object is stored in the memory area and to set up the second rights object on the digital right management device in case the information on the second rights object is not stored in the memory area and to reject the second rights object in case the information on the second rights object is stored in the memory area; wherein the at least one first rights object is only cryptographically bound to the DRM device before the at least one first rights object is moved to the another DRM device, such that only the DRM device can exercise the rights of the at least one first rights object before the at least one first rights object is moved to the another DRM device, wherein the at least one first rights object is deleted from the DRM device after the at least one first rights object is moved to the another DRM device, wherein the at least one first rights object is only bound to the another DRM device after the at least one first rights object is moved to the another DRM device, such that only the another DRM device can exercise the rights of the at least one rights object after the at least one first rights object is moved to the another DRM device, wherein the rights of the at least one first rights object are related to digital media content, wherein the device is configured to export stored information from the at least one first rights object from the memory area to an additional memory area, and to access the additional memory area, and wherein the processor is programmed or configured to compare a timestamp of the second rights object with the time information on the time when the last export took place before accessing the additional memory area, and to only access the additional memory area in case the timestamp of the second rights object indicates an issuance of the second rights object before the time when the last export took place.
