Abstract: A method for license interaction and interaction recovery after interruption overcomes the problems of mobility loss and waste of rights of the license due to interruption of communication during the license interaction. This method includes: when a first device and a second device interact on license information, both devices record the interaction related information; after the interaction is interrupted and the connection is re-established, the first device and the second device continue the interaction when determining that the interaction is uncompleted according to the recorded information. A communication device and a digital rights management (DRM) system are also disclosed.

Abstract: A method for operating a Right For Contents (R4C) includes: obtaining, by a terminal, a hybrid RO generated by the RI server, with the R4C items and the operation Rights For Rights (R4Rs) carried in the hybrid RO; operating the R4C items in the hybrid RO according to the R4R. A method for adding an R4R includes: a terminal receives a hybrid RO that includes the existing rights of the terminal and the newly added R4R; the terminal operates the R4C in the hybrid RO according to the new R4R. The present invention also discloses a terminal and a server. The present invention enables the RI to control the rights at a finer granularity, intensifies the RI's control on the rights, and provides a mechanism of purchasing an R4R after an RO is purchased.

Abstract: A method for backing up and restoring a license is provided, which solves the problem of right proliferation in the prior art caused when an original license is transmitted to a user when a server restores the license. The method includes: backing up, at a server, license information of a first device, and associating the license information with a user identifier, the license information reflecting the current state information of a license when the first device reports the license information the last time; requesting, by a second device, the server to restore the license; and validating, by the server, a user identifier of the second device and the user identifier associated with the license information, and upon determination that the two user identifiers are consistent, generating a license based on the license information backed up, and transmitting the license to the second device. A terminal device, a server, and a license processing system are also provided.
