METHOD OF TRANSFERRING DIGITAL RIGHTS

摘要

A system and method of transferring digital rights from a first device to a second device. A target rights management object is transferred from the first device to the second device. A probabilistic data structure is created that identifies each of a class of rights management objects that are present on the first device. The probabilistic data structure is employed to determine whether the target rights management object is present on the first device. The target rights management object is utilized on the second device in response to a determination through employment of the probabilistic data structure that the target rights management object is not present on the first device. The target rights management object and its state are returned to the first device in response to a determination through employment of the probabilistic data structure that the target rights management object is present on the first device.
