Method and System for Backing Up and Restoring License

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.

receiving, at a server, a license backup request which includes state information of the license and a first user identifier, wherein the state information reflects a current state of the constraints when the license is requested to be backed up; backing up, at the server, license information based upon the license backup request, and associating the license information with the user identifier, wherein state information of the license backed up is updated according to the state information in the license backup request, and wherein a license at a device, corresponding to the backed up license, is disabled; receiving, at the server, a license restoration request, which includes a second user identifier; validating, at the server, the second user identifier in the license restoration request according to the first user identifier associated with the license information backed up; and upon determination that the two user identifiers are consistent, sending a restored license based on the license information backed up to one of the user's devices.
