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.

摘要： 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.

摘要： A method for importing or moving a rights object (RO) is provided, 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.
摘要翻译：提供了一种用于导入或移动权限对象（RO）的方法，权利发行者（RI）接收向目标设备导入或移动RO的请求消息，该请求消息包括由目标的公开密钥封装的密钥信息设备; RI根据请求消息生成RO，RO包括由目标设备的公钥封装的密钥信息; 并且RI为目标设备提供RO。还提供RI。在本发明中，由RI提供由目标设备的公共密钥封装的密钥信息，并且真实密钥从RI隐藏，使得不信任RI不能为除其他设备之外的其他设备生成非法RO 目标设备，从而提高通过RI进口或移动RO的安全性。
