A file protection scheme for fixed content in a distributed data archive uses computations that leverage permutation operators of a cyclic code. In an illustrative embodiment, an N+K coding technique is described for use to protect data that is being distributed in a redundant array of independent nodes (RAIN). The data itself may be of any type, and it may also include system metadata. According to the invention, the data to be distributed is encoded by a dispersal operation that uses a group of permutation ring operators. In a preferred embodiment, the dispersal operation is carried out using a matrix of the form [IN<sub2>—< / sub2>C] where IN is an n×n identity sub-matrix and C is a k×n sub-matrix of code blocks. The identity sub-matrix is used to preserve the data blocks intact. The sub-matrix C preferably comprises a set of permutation ring operators that are used to generate the code blocks. The operators are preferably superpositions that are selected from a group ring of a permutation group with base ring Z2.

The present invention is a method of organizing and processing data in a distributed computing system. The invention is also implemented as a computer program on a computer medium and as a distributed computer system. Software modules can be configured as hardware. The method and system organizes select content which is important to an enterprise operating said distributed computing system. The select content is represented by one or more predetermined words, characters, images, data elements or data objects. The computing system has a plurality of select content data stores for respective ones of a plurality of enterprise designated categorical filters which include content-based filters, contextual filters and taxonomic classification filters, all operatively coupled over a communications network. A data input is processed through at least one activated categorical filter to obtain select content, and contextually associated select content and taxonomically associated select content as aggregated select content. The aggregated select content is stored in the corresponding select content data store. A data process from the group of data processes including a copy process, a data extract process, a data archive process, a data distribution process and a data destruction process is associated with the activated categorical filter and the method and system applies the associated data process to a further data input based upon a result of that further data being processed by the activated categorical filter utilizing the aggregated select content data.

Methods and systems are described for verifying stored data by receiving a first set of metadata associated with a first set of stored data, generating a second set of metadata associated with a second set of stored data which is associated with the first set of stored data, and comparing the first set of metadata and second set of metadata. Alternatively, the storage system can also generate a first set of metadata associated with a first set of stored data, generate a second set of stored data which is a copy of the first set of stored data, generate a second set of metadata associated with the second set of stored data, and compare the first set of metadata and the second set of metadata.

A file mark structure enables a disk drive in the magazine to emulate functionality of a tape cartridge.

A system for archive integrity management and related methods are disclosed. The invention includes one or more integrity manager applications, each of which monitor the integrity of an aspect of a data archive. Some integrity manager applications monitor the integrity of processes executed by the archive system, and other integrity manager applications monitor the integrity of communication paths in the archive system. A file input integrity manager application monitors the integrity of a plurality of processes associated with storing a new data file in the archive. A business content integrity manager application determines what documents are required for a transaction and monitors whether all of the required documents have been received by the archive system.

Systems, methods and computer program products are disclosed for providing long-term authenticity proof of an electronic document having a digital signature, wherein the electronic document is digitally signed with a digital signature and the electronic document and its digital signature are archived in a data archive. Such methods, systems and computer program products may store the electronic document in a first data archive and store a hash value of the electronic document in a second data archive different from the first data archive. Long-term authenticity and integrity may be achieved by periodically re-signing, particularly time stamping the hash value in the second data archive.

System and method for maintaining temporal data in data storage at the logical device level. Embodiments of the temporal volume manager may provide an interface that allows applications and / or application agents to communicate with the temporal volume manager to manage and keep track of the temporal information on one or more temporal volumes. Embodiments may provide an infrastructure for applications that work on the history of data such as temporal databases, versioning file-systems / repositories, data archives, and streaming media to manage temporal data. In one embodiment, if an application does not want to use the temporal volume directly, application agents may be used to access the temporal volume. Embodiments may provide I / O controlled, application-controlled, and / or periodic checkpointing of temporal data on the temporal volume. One embodiment may provide a mechanism for generating temporal images (e.g. point-in-time and slice-in-time images) of a temporal volume that may have their own independent history.

A method is for automatically indexing multimedia data archives and categorizing the files held therein and also to a client / server architecture in an image retrieval system for content-based searching for relevant files in a particular format and having a particular file structure. The parsed files stored in a data archive managed by the document management system are subjected to a feature extraction algorithm. The features obtained are then used for producing a binary-coded inverted index which includes elements of at least two attributes and holds context information which is held in these files and is needed for content-based image retrieval. If new files or files with an extended or modified content are stored in the data archive, then it involves a parsing algorithm and also an algorithm for automatically extracting features of these files being executed under event control during every storage process, in order to extend the inverted index by individual attributes or in order to update particular elements of already existing index attributes.
