    • A method and system for ownership transfer of digital content, in a secure system using digital rights management (DRM) to handle user access to stored content, comprising receiving instructions from a first user being a current owner of a piece of content to transfer ownership of said piece of content to a second user, granting said second user an ownership takeover right to said piece of content, said ownership takeover right only being grantable by a current owner, receiving an accept from said second user, and identifying said second user as new current owner of said piece of content. According to this solution, the transfer of the ownership can be handled at the level of digital rights management, by introducing new rights (e.g. an "Ownership Takeover" right). This moves the ownership transfer protocol from the device specific implementations to the DRM specific implementations, which allows transfer of ownership between interoperable DRM systems.
    • 一种用于数字内容的所有权转让的方法和系统,在使用数字版权管理(DRM)来处理对存储的内容的用户访问的安全系统中,包括接收来自作为一条内容的当前所有者的指令, 向所述第二用户表示所述内容,向所述第二用户授予对所述内容的所有权接管权,所述所有权接管权仅由当前所有者授予,接收来自所述第二用户的接受,并将所述第二用户识别为新的 目前所有者的内容。 根据这一解决方案,所有权的转让可以通过引入新的权利(例如“所有权接管权”)在数字版权管理层面处理。 这将所有权转移协议从设备特定实现转移到DRM特定实现,这允许在可互操作DRM系统之间传递所有权。
