System and method for monitoring unauthorized transport of digital content
First Claim
1. A system for intercepting content being forwarded over a network, for monitoring the content prior to forwarding, comprising:
- at least one micro-processor and a non-volatile computer readable storage medium,a transport data monitor, connectable to a point in a network, and configured to intercept and monitor data being transported past said point,a description extractor, associated with said transport data monitor, for extracting descriptions of content of said data being transported,a database of at least one preobtained description of content whose movements it is desired to monitor,a comparator configured to determine whether said extracted description corresponds to any of said at least one preobtained descriptions, thereby to determine whether said data being transported comprises any of said content whose movements it is desired to monitor,wherein said description extractor is configured to extract said content descriptors using only partial basic decoding of said data.

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.
