Abstract: A method in one example implementation includes extracting a plurality of data elements from a record of a data file, tokenizing the data elements into tokens, and storing the tokens in a first tuple of a registration list. The method further includes selecting one of the tokens as a token key for the first tuple, where the token is selected because it occurs less frequently in the registration list than each of the other tokens in the first tuple. In specific embodiments, at least one data element is an expression element having a character pattern matching a predefined expression pattern that represents at least two words and a separator between the words. In other embodiments, at least one data element is a word defined by a character pattern of one or more consecutive essential characters. Other specific embodiments include determining an end of the record by recognizing a predefined delimiter.

Abstract: A document accessible over a network can be registered. A registered document, and the content contained therein, cannot be transmitted undetected over and off of the network. In one embodiment, the invention includes maintaining a plurality of stored signatures, each signature being associated with one of a plurality of registered documents, intercepting an object being transmitted over a network, calculating a set of signatures associated with the intercepted object, and comparing the set of signatures with the plurality of stored signatures. In one embodiment, the invention can further include detecting registered content from the registered document being contained in the intercepted object, if the comparison results in a match of at least one of the signatures in the set of signatures with one or more of the plurality of stored signatures.

Abstract: A system and method for locational tagging in a capture system are described. Metadata associated with a captured object includes: information about a location in storage of an object and that objects association to a particular user; and/or tiered location information.

Abstract: A document accessible over a network can be registered. A registered document, and the content contained therein, is not transmitted undetected over and off of the network. In one embodiment, the invention includes a manager agent to maintain signatures of registered documents and a match agent to detect the unauthorized transmission of the content of registered documents.

Abstract: Content leaving a local network can be captured and indexed so that queries can be performed on the captured data. In one embodiment, the present invention comprises an apparatus that connects to a network. In one embodiment, this apparatus includes a network interface module to connect the apparatus to a network, a packet capture module to intercept packets being transmitted on the network, an object assembly module to reconstruct objects being transmitted on the network from the intercepted packets, an object classification module to determine the content in the reconstructed objects, and an object store module to store the objects. This apparatus can also have a user interface to enable a user to search objects stored in the object store module.

Abstract: Objects captured over a network by a capture system can be indexed to provide enhanced search and content analysis capabilities. In one embodiment the objects can be indexed using a data structure having a source address field to indicate an origination address of the object, a destination address field to indicate a destination address of the object, a source port field to indicate an origination port of the object, a destination port field to indicate a destination port of the object, a content field to indicate a content type from a plurality of content types identifying a type of content contained in the object, and a time field to indicate when the object was captured. The data structure may also store a cryptographic signature of the object to ensure the object is not altered after capture.

Abstract: A system and method for capturing objects and balancing systems resources in a capture system are described. An object is captured, metadata associated with the objected generated, and the object and metadata stored.

Abstract: Objects can be extracted from data flows captured by a capture device. In one embodiment, the invention includes assigning to each captured object a cryptographic status based on whether the captured object is encrypted. In one embodiment, the invention further includes determining whether the object violated a cryptographic policy using the assigned cryptographic status of the object.

Abstract: Systems and related methods are described for handling one or more resource requests. A protocol engine receives a resource request in accordance with a prescribed protocol, and a classification engine determines a desired class of service for the request. An analysis engine optionally analyzes the request, and, responsive thereto, determines a desired sub-class of service for the request. A policy engine then allocates a resource to the request responsive to one or both of the desired class of service, and the desired sub-class of service.

Abstract: A document accessible over a network can be registered. A registered document, and the content contained therein, cannot be transmitted undetected over and off of the network. In one embodiment, the invention includes maintaining a plurality of stored signatures over a registered document. In one embodiment, the plurality of stored signatures are generated by extracting content from the document, normalizing the extracted content, and generating the plurality of signatures using the normalized content.
