摘要： A method for importing or moving a rights object (RO) is provided, which includes the following steps. A rights issuer (RI) receives a request message of importing or moving an RO to a target device, the request message including key information encapsulated by a public key of the target device; the RI generates the RO according to the request message, the RO including the key information encapsulated by the public key of the target device; and the RI provides the RO for the target device. An RI is also provided. In the present invention, the key information encapsulated by the public key of the target device is provided for the RI, and the real key is hidden from the RI, such that the un-trust RI cannot generate the illegal RO for other devices except the target device, thereby enhancing the security of importing or moving the RO through the RI.

摘要： 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.
