摘要： Techniques for securing content in an untrusted environment are provided. Content is encrypted and stored with a content delivery service in an encrypted format. Encrypted versions of a content encryption/decryption key and a first key are also housed and distributed by the content delivery service. The first key is used to decrypt the encrypted version of the content encryption/decryption key. The content delivery service is unaware of the content encryption/decryption key and the first key; and the content held by the content delivery service is encrypted with the content encryption/decryption key. Principals securely share, create, manage, and retrieve the encrypted versions of the content encryption/decryption key and the first key from the content delivery service using secure communications. The encrypted content is obtainable via insecure communications from the content delivery service.

摘要： Apparatus, systems, and methods may operate to receive a request to access a file from a client node at one of a plurality of lookup nodes, the lookup nodes storing portions of a distributed table having lookup information associated with the file. The distributed table, which may comprise a distributed hash table, includes replicated references to virtualized and non-virtualized file elements of varied granularity in a unified file system. Additional activity may comprise forwarding the request to another one of the lookup nodes until the lookup information is located, or chaining the request to one of the plurality of lookup nodes and implementing activity that has been requested. Additional apparatus, systems, and methods are disclosed.

摘要： Techniques for universal content traceability are presented. A piece of content is tagged with one or more content identifiers and with a unique instance identifier. The content also is tagged with content and instance-level metadata. The tagged information is maintained with the document and separately from the document in a centralized or distributed database system or table. As operations are performed on the content, the tagged information may be updated as necessary. The content can then use the tagged information in connection with the database to trace its origins and history during its lifecycle.
摘要翻译： 介绍了通用内容可追溯性的技术。 一条内容用一个或多个内容标识符和唯一的实例标识符标记。 内容还被内容和实例级元数据标记。 标签信息与文档保持一致，并在集中式或分布式数据库系统或表中与文档分开。 当对内容执行操作时，可以根据需要更新标记的信息。 然后，内容可以使用与数据库相关联的标记信息来在其生命周期中跟踪其起源和历史。
