A system and method of operating a filesystem for managing filesystem objects is disclosed. The filesystem objects are characterized by metadata parameters included in a global directory object arranged in a plurality of global directory object (GDO) pages. Responsive to receiving a request for creating a new filesystem object, a parent key is obtained. The parent key is indicative of an identifier of a direct parent directory requested for hosting the new filesystem object. A target page that corresponds to the parent key is located within the plurality of GDO pages. The target page further includes a direct parent directory metadata record associated with the direct parent key and includes metadata parameters related to the direct parent directory. An object key is created as corresponding to the same target page, thereby enabling accommodation of an object metadata record, related to the new filesystem object, on the target page.

Described is a process for secure and privacy-preserving data retrieval operations in a network having a plurality of nodes. The process includes receiving a query at a querying node. The query is encrypted to generate an encrypted metadata query record. The encrypted metadata query record is transmitted to each queried node that is to be searched for data. A secure pattern matching protocol is used to search a database of metadata records to match a query answer to the metadata query record. The query answer is then encrypted. A query policy is verified for the querying node, with the encrypted answer being further encrypted based on the query policy. The further encrypted answer is transmitted to the querying node, which removes the outer layer of encryption, resulting in the original encrypted answer. The original encrypted answer is then decrypted to recover the query answer.

An optical disk contains main video data obtained by compressing pictures captured by a video camera at a relatively low compression ratio, low resolution proxy video data obtained by performing compression at a compression ratio higher than that for the main video data, metadata for use in editing. When a state in which the optical disk 2 is loaded into a drive of an optical disk apparatus is detected, the proxy video data and the metadata are read and recorded in a hard disk drive (HDD) without receiving a user's instruction. The proxy video data and metadata recorded in the HDD are used in simple editing before main editing in which the main video data is edited.

A method for providing proximate dataset recommendations can begin with the creation of metadata records corresponding to datasets that represent scientific data by a scientific dataset search tool. The metadata records can conform to a standardized structural definition, and may be hierarchical. Values for the data elements of the metadata records can be contained within the datasets. Metadata records with a value that is proximate to a user-entered search parameter can be identified. A proximity score can be calculated for each identified metadata record. The proximity score can express a relevance of the corresponding dataset to the user-entered search parameters. The identified metadata records can be arranged in descending order by the calculated proximity rating, creating a list of proximate dataset results. The proximate dataset results can be presented within a user interface.

The invention discloses a flash memory storage system and a reading, writing and deleting method thereof. The flash memory storage system comprises a cache, a main control module, a cache metadata record sheet, a read mapping table and a write mapping table. The write mapping table is used for being stored in the cache and writing in the correspondence of a logical storage block and a physical storage block. The read mapping table is used for being stored in the cache and reading out the correspondence of the logical storage block and the physical storage block. The cache metadata record sheet is used for storing correspondences of metadata sheet addresses, the physical storage blocks and rear end flash memory addresses. By means of the flash memory storage system, the unnecessary write-in or read-out of a rear end flash memory can be reduced, the zero copy on a read-write data channel is achieved, the unnecessary intermediate copy process is omitted, and therefore the read-write efficiency is improved; the size of the read-write access of a front end application can be matched with the size of the rear end flash memory.

In one embodiment, file attributes of a desired file are sent along with the URL to the storing server and the attributes are used for subsequent retrieval of the file. Attributes, such as the text or title of the file, the language of the file, the creator of the file, etc, can all be added to the file in the form of metadata. Files that are recorded without metadata can have metadata attached thereto and can be retrieved using the metadata. The URL initially carries the metadata to the server and the server then both uses the metadata for indexing purposes and, if desired, adds the metadata to the file for storage with the file. In one embodiment, the files are media files used in an IVR system.

A system to catalog and search point-in-tine instances of a file system is disclosed. A catalog engine takes backups of file data generated by a storage system and catalogs the backups of file data into a searchable catalog of independent metadata records. The metadata is represented by baseline structure and delta files.

A system and method for supporting parallel logging of changes to a data file by a server while allowing an application to continue writing changes to the data file. In response to changes to a data file, a near-instant version of the file is created. Metadata reflecting changes to the data files are synchronized with versions of the files in the cache and recorded to persistent storage. In the process of recording metadata changes for a file, subsequent changes to the data file can proceed, and metadata reflecting the change can be recorded in a subsequent, near-instantaneous version of the file, which can also be Synchronized with the version of the metadata in persistent storage.
