First Claim
1. A method for sharing a license between Secure Removable Media (SRM), comprising:
- obtaining, by a Digital Rights Management (DRM) agent, the license from a first SRM, and setting the license to a forwarding state locally;

Abstract
A method and an apparatus for sharing a license between SRMs are disclosed. The method includes: a DRM agent obtains the license from a first SRM, and sets the license to a forwarding state locally; the DRM agent deducts one right of sharing the license; and the DRM agent sends the license to a second SRM. In the prior art, one moving right is deducted when the license moves from SRM1 to the device, and the other moving right is deducted when the license moves from the device to SRM2. By contrast, in the technical solution under the present invention, the license forwarded by the DRM agent is set to the forwarding state, and only one sharing right needs to be deducted, and therefore, the consumption of the sharing rights is reduced and the subscriber'"'"'s rights are protected.
