Abstract: Systems and methods for optimizing deduplication in a data storage system are provided. The method comprises associating a first name with first data blocks including first content stored in a data storage system, wherein the first name is associated with the first data blocks by way of a reference to a first meta file that points to a data file which points to the first data blocks; storing a first signature derived from the first content in an indexing data structure, wherein the first signature is used to associate the first name with the first data blocks and as means to verify whether a second content is a duplicate of the first content, based on value of a second signature derived from the second content.

Abstract: A novel and useful method of implementing a full coverage low power mode in a storage system comprised of one or more memory storage devices storing replicated data items. A subset of the memory storage devices is chosen whose replicated data items require the least amount of storage. If the chosen subset stores uncovered data items, these data items are copied to an auxiliary memory storage device. The storage system can enter a full coverage low power mode by powering down the chosen subset of memory storage devices.

Abstract: A method for enforcing compliance in both the copy protect domain and service subscription domain for streamed multicast data. Each content is encrypted with a title key that itself is encrypted with a channel unique key which is a hash of a session key and a channel key. A compliant player is given the channel key upon registration for a subscription service (representing subscription protection) and is also given device keys upon activation (representing copy protection) for decrypting the session key. Consequently, the channel unique key can be obtained (and, hence, the content decrypted) only by a player that is compliant with both copy protection rules and subscription rules. The channel key can be refreshed periodically as subscriptions change or expire.

Abstract: In accordance with one or more embodiments, an inode implemented file system may be utilized to support both offline and inline deduplication. When the first content is stored in the storage medium, one inode is used to associate a filename with the data blocks where the first content is stored. When a second content that is a duplicate of the first content is to be stored, then a parent inode is created to point to the data blocks in which a copy of the first content is stored. Further, two inodes are created, one representing the first content and the other representing the second content. Both inodes point to the same parent inode that points to the data blocks where the first content is stored.

Abstract translation: 根据一个或多个实施例，可以使用inode实现的文件系统来支持脱机和内联重复数据删除。 当第一内容存储在存储介质中时，使用一个inode来将文件名与存储第一内容的数据块相关联。 当要存储与第一内容重复的第二内容时，创建父节点，以指向存储第一内容的副本的数据块。 此外，创建两个inode，一个代表第一内容，另一个代表第二内容。 两个inode指向同一个父节点，它指向存储第一个内容的数据块。

Abstract: A tree is used to partition stateless receivers in a broadcast content encryption system into subsets. Two different methods of partitioning are disclosed. When a set of revoked receivers is identified, the revoked receivers define a relatively small cover of the non-revoked receivers by disjoint subsets. Subset keys associated with the subsets are then used to encrypt a session key that in turn is used to encrypt the broadcast content. Only non-revoked receivers can decrypt the session key and, hence, the content.

Abstract translation: 一棵树用于将广播内容加密系统中的无状态接收器分成子集。 公开了两种不同的分割方法。 当识别出一组撤销的接收者时，撤销的接收者通过不相交的子集定义非撤销的接收者的相对较小的覆盖。 与子集相关联的子集密钥然后用于加密会话密钥，会话密钥又用于加密广播内容。 只有非撤销的接收者可以解密会话密钥，因此可以解密内容。

Abstract: The present invention provides for the protection of and ability to upgrade to new formats of digital content by providing consumers of the digital content the capability of purchasing content insurance on digital content they consume. By purchasing insurance on content, at a later time consumers are able to return to the content distribution channels and re-obtain the previously purchased content in the same, or new format as the original purchased.
