    Abstract: Various mechanisms are provided for the lockdown of an item store. For example, a method is provided that comprises of disabling access to a relational engine for a set of users associated with a filing system utilizing the relational engine to manipulate data in an item store. Following such disabling of access, an exception is created by allowing access to the relational engine for users of the filing system based on a set of privileges the users have been assigned. The disabling of access can be accomplished by removing system users from ownership roles, and the allowing of access can be accomplished by providing certificates to users that have associated set of privileges granted to the users.

    Abstract: An operating system for a computing device has a first session for a user that includes a first base process that has a first privileges token attached thereto. The first privileges token includes substantially a full set of privileges of the user on the operating system. The operating system also has a second session for the user that includes a second base process that has a second privileges token attached thereto. The second privileges token is derived from the first privileges token and includes only a minimum set of privileges of the user on the operating system. Thus, the second, limited token does not have all privileges associated with the first, full token but instead has a limited set of privileges and not extra privileges that could be employed to take actions that would be harmful, deceptive, or malicious.

    Abstract translation: 用于计算设备的操作系统具有用于用户的第一会话，所述第一会话包括具有连接到其的第一权限令牌的第一基本进程。 第一权限令牌在操作系统上基本上包括用户的一整套特权。 操作系统还具有用户的第二会话，其包括具有附加到其的第二权限令牌的第二基本进程。 第二个权限令牌是从第一个权限令牌导出的，并且仅包含操作系统上用户的一组最小权限。 因此，第二个有限令牌不具有与第一个完整令牌相关联的所有权限，而是具有一组有限的权限，而不是可以用于采取有害，欺骗性或恶意行为的额外权限。

    Abstract: Various embodiments utilize a third party, such as a trusted third-party, to perform DRM operations such as “move” operations. In at least some embodiments, the trusted third-party is utilized for both “move” operations as well as local content access such as playback and the like. In at least some embodiments, a third-party maintains a database that includes an association of clients, content, and move version numbers. A client—termed a “source client” maintains at least a move version number locally in a secure fashion. The version number is incremented each time the source client performs a move operation. Both the source client and the third-party increment the version number each time a piece of content is moved. When the client attempts to perform a move operation, it contacts the third-party to ascertain the third-party's move version number. If the move version numbers match and the source client owns the license/content, then, in at least some embodiments, a move operation is permitted.

    Abstract: Various embodiments provide a mapping layer to translate DRM system requirements from one DRM system, such as a source system, to another DRM system, such as a target system. In at least some embodiments, DRM system requirement translation is performed using a signed data structure that maps DRM system requirements from one DRM system to one or more other DRM systems. By mapping DRM system requirements from one system to another, licenses associated with DRM-protected content and associated content can be safely transferred between systems.

    Abstract: Techniques enable seamless movement and consumption of licensed digital content amongst multiple devices. In some embodiments, these techniques allow establishment of a domain capable of having multiple member devices. Each member device of the domain typically comprises a content-consuming device such as a personal computer, a portable media player, or the like. These techniques enable a license associated with digital content to bind to a domain rather than an individual device. As such, each member device of the domain may contain a domain identity and, with the identity, may consume the content with use of the license and in accordance with policy described in the license. These tools may also enable a member device to join multiple domains and to contain an identification of each of these multiple domains.

    Abstract translation: 技术可以在多个设备之间实现许可数字内容的无缝移动和消费。 在一些实施例中，这些技术允许建立能够具有多个成员设备的域。 域的每个成员设备通常包括诸如个人计算机，便携式媒体播放器等的内容消费设备。 这些技术使得与数字内容相关联的许可证能够绑定到域而不是单个设备。 因此，域的每个成员设备可以包含域身份，并且具有身份的消费者可以使用许可证并且根据许可证中描述的策略来消费该内容。 这些工具还可以使成员设备加入多个域并且包含这些多个域中的每一个的标识。

    Abstract: A system that generates a per user abstraction of a store from a connection point. Filtering a view set of a hierarchically secured containment hierarchy based on the access permissions of the principal is one of the novel features of the invention. The invention can offer a collection of primitives that can operate on this aggregation that span multiple container hierarchies with potentially heterogeneous security descriptors. The model can reduce the necessity to traverse the container hierarchy to discover all the accessible items in a domain.
