摘要： 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.

摘要： Various embodiments provide content protection interoperability techniques which support secure distribution of content for multiple content protection technologies. In one or more embodiments a source digital rights management (DRM) system can associate trust data with content to be exported to a target digital rights management (DRM) system. The trust data describes a trust state for the content to enable the target DRM system to maintain the trust state for the exported content. In at least some embodiments, the source DRM system can also associate tracing data with the content to, in the event of a breach in the chain of trust, enable an identification to be made of a source of the exported content and/or a party responsible for exporting the content.
摘要翻译：各种实施例提供了支持多内容保护技术的内容的安全分发的内容保护互操作性技术。在一个或多个实施例中，源数字版权管理（DRM）系统可以将信任数据与要导出到目标数字版权管理（DRM）系统的内容相关联。信任数据描述了内容的信任状态，以使目标DRM系统能够维护导出的内容的信任状态。在至少一些实施例中，源DRM系统还可以将跟踪数据与内容相关联，以便在信任链中的违反情况下使得能够对导出的内容的源和/或一方进行识别负责出口内容。

摘要： This document describes tools capable of renewing an expired license to entertainment content. The tools, in some embodiments, may repeatedly renew a license using very little resources, such as by forgoing retention of the license, encryption keys, or the entertainment content between renewals. The tools, for example, may provide a license to a particular content receiver (e.g., a laptop computer), and, when that license expires, renew the license with as little as a single retained secret. By so doing the tools enable, among other things, fewer computing resources to be used in renewing a license while maintaining the security of that license's entertainment content.
摘要翻译：本文档描述了能够将已过期许可证更新为娱乐内容的工具。在一些实施例中，这些工具可以使用非常少的资源来重复地更新许可证，例如通过在续订之前保留许可证，加密密钥或娱乐内容。例如，这些工具可以向特定内容接收器（例如，膝上型计算机）提供许可证，并且当该许可证到期时，以仅一个保留的秘密来更新许可证。通过这样做，除了别的以外，这些工具还能够在维护许可证娱乐内容的安全性的同时更新许可证中使用的更少的计算资源。

摘要： Techniques enable building a collection of data that defines an asset, with the data possibly having differing data types. These techniques are then capable of assigning arbitrary policy to that asset, regardless of which data types are present within the asset. In addition, these techniques enable packaging of this first asset with one or more additional assets in a self-contained envelope. Each asset within the envelope may similarly include data of differing data types. Furthermore, each of these assets may be assigned a policy that may be different than the policy assigned to the first asset. This envelope, or a collection of envelopes, may then be provided to a content-consuming device to consume the assets in accordance with each asset's specified policy.

摘要： A content license associated with unencrypted digital content is generated, the content license including both an identifier of the unencrypted digital content and a content policy. At a user device, a determination is made as to whether the content license corresponds to particular unencrypted digital content. Use of the particular unencrypted digital content by the computing device is permitted in accordance with the content policy if the content license corresponds to the particular unencrypted digital content. However, use of the particular unencrypted digital content by the computing device based on the content license is prohibited if the content license does not correspond to the particular unencrypted digital content.

摘要： The restriction of particular resources includes providing a digital signature for unauthorized resources based on a structure-related parameter of the resource. Thus, attempts at circumventing recognition of such resource will likely result in altering the overall functionality of the resource. Further, such digital signatures are encoded in a critical file required for loading of a resource, thus ensuring that the identity of the resource is considered before execution thereof. Enforcement of the resource restriction includes generating a verification signature for a resource that requests loading. The verification signature is compared to the signature coded into the critical file, and a positive match results in the resource being blocked from loading.
摘要翻译：特定资源的限制包括基于资源的结构相关参数为未授权资源提供数字签名。因此，绕过这种资源的识别的尝试可能导致改变资源的整体功能。此外，这样的数字签名被编码在加载资源所需的关键文件中，从而确保在执行资源之前考虑资源的身份。资源限制的执行包括为请求加载的资源生成验证签名。将验证签名与编码到关键文件中的签名进行比较，并且肯定匹配导致资源被阻止加载。
