    • In a right management server (100), a license data generation/updating unit (307) generates license data (900) including a use condition (503) for permitting a user to use a content based on a content use right (500) owned by the user. A subset use condition setting unit (308) sets a subset use condition (901) for temporarily invalidating the license data (900) in the license data (900). A communication unit (311) transmits the license data (900) in which the subset use condition (901) is set to the user terminal (110), and receives the license data (900) returned from the user terminal (110). Upon receipt of the invalidated license data (900), the license data generation/updating unit (307) cancels the invalidation of the license data (900) by updating the subset use condition (901).
    • 在权利管理服务器(100)中,许可数据生成/更新单元(307)生成许可数据(900),其包括使用条件(503),用于允许用户基于所拥有的内容使用权(500)使用内容 由用户 子集使用条件设置单元(308)设置用于临时使许可证数据(900)中的许可数据(900)无效的子集使用条件(901)。 通信单元(311)将其中设置了子集使用条件(901)的许可数据(900)发送到用户终端(110),并且接收从用户终端(110)返回的许可证数据(900)。 许可证数据生成/更新部(307)在接收到无效许可数据(900)后,通过更新子集使用条件(901)来取消许可证数据(900)的无效。

    • An application management device 54 that is capable of judging the necessity of application deletion with little load includes: a DRM application DB 520 that stores plural applications in association with their respective identification information (DRM application IDs) for identifying a correspondence between a license and an application for processing such license; and a DRM application deletion judgment unit 527 that judges, for each of the applications stored in the DRM application DB 520, whether deletion of an application is necessary or not, based on the identification information. More specifically, the application management device 54 further includes a license DB 521 for storing each license in association with the identification information, and the DRM application deletion judgment unit 527 judges that an application whose license associated with the identification information is not stored in the license DB 521, is an application to be deleted.
    • 能够以少量负载判断应用删除的必要性的应用管理设备54包括:DRM应用DB 520,其与其各自的识别信息(DRM应用ID)相关联地存储多个应用,用于识别许可证和 申请处理该等牌照; 以及DRM应用删除判定单元527,根据识别信息,判断存储在DRM应用DB 520中的每个应用是否需要删除应用。 更具体地说,应用程序管理装置54还包括用于与识别信息相关联地存储每个许可的许可DB 521,并且DRM应用删除判断单元527判断与该识别信息相关联的许可证的应用未被存储在许可证中 DB 521,是要删除的应用程序。
