发明名称 Digital rights management backup and restoration system and method
摘要 A digital rights management (DRM) system allows for digital data to be delivered to a user, and user rights to be stored by a locker service by the content provider. The rights may be stored in the locker service by request of the user. If the content is then lost, corrupted, or otherwise unavailable or unusable by the user, or in other appropriate circumstances, the user may contact the locker service and obtain authorization to re-access (e.g., download) another copy of the content. The system may verify user compliance with the DRM scheme prior to authorizing re-provisioning of the content.
