Abstract: 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.

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 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.

Abstract: A computer-implemented method for processing information includes collecting data objects from one or more data repositories, the data objects having respective properties, which identify the data objects. The properties of the collected data objects are analyzed in order to derive respective identifiers corresponding to the data objects. A text string that matches one of the identifiers of a data object is identified within a context in a document. Responsively to the context, an indication that the identified text string is a valid instance of the data object is generated, and the document is processed responsively to the indication.

Abstract: A method for determining compliance with a data distribution or usage policy applied with respect to a digital medium is presented. The method comprising: assigning numerical values to breaches of the policy; assigning a quota of breaches of the policy to at least one user subjected to the policy, the quota being expressed in terms of the numerical value; monitoring information distribution or usage covered by the policy in order to detect breaches of the policy by users; upon detection of an action breaching the policy by a given one of the users: determining whether a numerical value has been assigned to the type of the breach; comparing the numerical value assigned to the type of breach with a respective quota assigned to the given user, and allowing the action to be executed only if the comparing indicates that the respective quota assigned to the given user is sufficient to cover the breach.

Abstract: 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.

Abstract: A method for secure distribution of digital content to an untrusted environment, comprising the steps of; constructing a relatively trusted environment within the untrusted environment; constructing at least two digital inputs, the digital inputs are operable in order to reproduce the digital content; transferring digital media to the relatively trusted environment such that each of the inputs is transmitted via a different path, and combining the inputs in order to reproduce the digital content.

Abstract: A method for secure distribution of digital content, the method including the steps of dividing a unit of digital content into at least first and second portions, storing the first portion on a first computerized apparatus, digitally watermarking the second portion, and combining the first portion and the digitally watermarked second portion, thereby forming a watermarked version of the digital content.

Abstract: A method of distributing digital content or service over a communication network is provided. The method is effected by: (a) analyzing a request for distribution of the digital content or service; (b) generating a policy associated with the digital content or service; and (c) assembling a distribution syndicate of distribution entities, the distribution entities being selected according to the policy associated with distribution of the digital content or service, the distribution syndicate being for distributing the digital content or service over the communication network.

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.
