A method for computer workstation based information protection is presented, the method comprises: a) monitoring user's actions on the computer workstation, b) analysis of the actions in respect to a pre-defined policy to determine whether the actions prejudice information to which the policy applies, and c) executing the policy in accordance with the results of the analysis to prevent or modify or restrict or monitor or log the actions.

Method and system for protecting confidential information

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.

Method and application for a reactive defense against illegal distribution of multimedia content in file sharing networks

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.

System and method for monitoring unauthorized transport of digital content

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.

Method and a system for embedding textual forensic information

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.

Apparatus and method for controlling unauthorized dissemination of electronic mail

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.

Method and system for managing confidential information

A method for detecting an information item within an information sequence obtained from a digital medium, the information item comprising any one of a specified set of prestored information items, comprises: transforming each of the set of prestored information items into a respective representation, in accordance with a predetermined transformation format; transforming the information sequence obtained from the digital medium, in accordance with the transformation format; and determining the presence of one or more of the prestored information items within the transformed information sequence, utilizing the respective representation.

Method and a system for information identification

According to a first aspect of the present invention, a method for enforcing a distribution policy with respect to information transmitted from a sending fax machine to a recipient fax machine as fax traffic is presented. The method comprising defining an information distribution policy with respect to the fax traffic, then monitoring the fax traffic in accordance with the distribution policy, where the monitoring comprising: (i) de-modulating the fax traffic being monitored into a digital stream; (ii) reconstructing from the digital stream a graphic image representing at least part of the information within the fax traffic; and (iii) analyzing information within the reconstructed image, and then applying the distribution policy with respect to the analyzed fax traffic.

Method and system for distribution policy enforcement on fax

A method for enforcing a distribution policy associated with an electronic document comprising the steps of: sending the document to an output device; determining said distribution policy associated with said document; instructing a marking module to embed a marking indicating at least the existence of said distribution policy on an output form of said electronic document produced by said output device, said marking being readable to enforce said associated marking policy.

System and method for monitoring unauthorized dissemination of documents and portable media

A method and apparatus for providing multi-domain control over a digital data item via a first domain security policy assigned to the digital data item at a first domain, the data item being transferred from the first domain to a second domain, the second domain being autonomous from the first domain in respect of security policies. The method comprises assigning the security policy to the digital item within the first domain; transferring the digital items to the second domain together with data defining the first domain security policy; analyzing the first domain security policy within the second domain; and distributing and/or allowing usage of the digital items within the second domain in accordance with analyzed first domain security policy, and/or reporting breaches or attempted breaches of the policy.
