    摘要: A number of digital content rendering modules are equipped such that selective subsets of the modules may be employed to render digital content of different media, and of different format types. The modules are organized into a hierarchy, with a selected one occupying a root position of the hierarchy, to exclusively receive the digital contents to be rendered, and that each module is further responsible for verifying the integrity of its immediate downstream modules, to collectively protect the digital contents being rendered. Additionally, in accordance with another aspect, a tamper resistant module is employed to recover digital contents provided in a protected state, obfuscating the recovery. Further, the modules may be of different application domains.

    摘要: The intelligent distributed file system enables the storing of file data among a plurality of smart storage units which are accessed as a single file system. The intelligent distributed file system utilizes a metadata data structure to track and manage detailed information about each file, including, for example, the device and block locations of the file's data blocks, to permit different levels of replication and/or redundancy within a single file system, to facilitate the change of redundancy parameters, to provide high-level protection for metadata, to replicate and move data in real-time, and so forth.

    摘要: In one embodiment, a user or client device is connected to a distributed file system comprised of one or more physical nodes. The data on each of the physical nodes store metadata about files and directories within the file system. Some of the embodiments permit a user to take a snapshot of data stored on the file system. The snapshot may include a single file, a single directory, a plurality of files within a directory, a plurality of directories, a path on the file system that includes nested files and subdirectories, or more than one path on the file system that each includes nested files and directories. In one embodiment, the metadata comprises mini-snapshots for directories representing a path from the root of the file system to the root of the snapshot. The mini-snapshots serve as stand-ins for portions of the file system which are not included in the snapshot, but which permit access to the snapshot data in an intuitive way.

In one embodiment, previous versions of a file or directory are stored only in response to a request to modify the file or directory. The system creates and updates a snapshot tracking data structure which provides information regarding each file or directory governed by the snapshot that was modified or deleted after the snapshot was taken. The snapshot tracking data structure may be used by the system to perform functions related to the snapshot, including deleting the snapshot.
