Abstract: A method of classifying documents. The method comprises providing a document mapping classifying dataset comprising document feature datasets, each one of the document feature datasets documenting document features of one of a plurality of documents, each one of the documents is associated with a structurality level and classified as related to one of a plurality of database specific categories, extracting a current document feature dataset from a document, performing an analysis of each of at least some of the document feature datasets to identify a similarity to the current document feature dataset while adjusting a dynamic similarity threshold according to a respective the structurality level of an associated document from the documents, selecting one of the documents according to the similarity, and classifying the current document as a member of a respective the database specific category of the selected document.

Abstract: A system for external monitoring of networked digital file sharing to track predetermined data content, the system comprising: at least one surveillance element for deployment over said network, said surveillance elements comprising: surveillance functionality for searching said digital file sharing and identification functionality associated with said search functionality for identification of said predetermined data content, therewith to determine whether a given file sharing system is distributing said predetermined data content.

Abstract: A system for network content monitoring and control, comprising: a transport data monitor, connectable to a point in a network, for monitoring data being transported past said point, a signature extractor, associated with said transport data monitor, for extracting a derivation of said data, said derivation being indicative of content of said payload, a database of preobtained signatures of content whose movements it is desired to monitor, and a comparator for comparing said derivation with said preobtained signatures, thereby to determine whether said payload comprises any of said content whose movements it is desired to monitor. The monitoring result may be used in bandwidth control on the network to restrict transport of the content it is desired to control.

Abstract: A method for automatically embedding information in a digital text, said method comprising: identifying a plurality of positions, in said digital text, that are suitable for introducing modifications into said digital text; identifying modifications suitable for introduction into at least some of said suitable positions in said digital text; selecting at least some of said identified modifications for introduction into said digital text, said selection of said modifications being operable to represent said information; and performing said selected modifications on said digital text, thereby to embed said information.

Abstract: A method for classification and enforcement of security requirements in an information dissemination system, said information dissemination system not being designed for said security requirements and enforcement. The method comprising the steps of: accepting a user specification of said security requirements for dissemination of respective information, said specifying is done using a user interface; Associating with said dissemination system an enforcement module, said module being operable to receive said security requirements and apply them to control dissemination via said dissemination system, and then enforcing said dissemination via said module.

Abstract: A method and a system for information management and control is presented, based on modular and abstract description of the information. Identifiers are used to identify features of interest in the information and information use policies are assigned directly or indirectly on the basis of the identifiers, allowing for flexible and efficient policy management and enforcement, in that a policy can be defined with a direct relationship to the actual information content of digital data items. The information content can be of various kinds: e.g., textual documents, numerical spreadsheets, audio and video files, pictures and images, drawings etc. The system can provide protection against information policy breaches such as information misuse, unauthorized distribution and leakage, and for information tracking.

The monitoring result may be used in bandwidth control on the network to restrict transport of the content it is desired to control.

Abstract: A computer-implemented method for document management includes extracting from an input document a set of terms, each term including a fixed number of words. Respective numbers of the terms that occur in each of a group of stored documents are counted, and a respective association rate is computed between the input document and each of at least some of the stored documents responsively to the respective numbers of the terms that were counted in the stored documents. One or more of the stored documents are identified as versions of the input document responsively to the association rate, and an identification of the stored documents that are versions of the input document is outputted.
