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.

Dependent claims

A system for network content monitoring, comprising:

at least one processor and an electronically readable medium,
a transport data monitor, connectable to a point in a network, for monitoring data being transported past said point,
a description extractor, associated with said transport data monitor, for extracting descriptions of said data being transported,
a database of at least one preobtained description of content whose movements it is desired to monitor,
a comparator for determining 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, and
certification recognition functionality to recognize data sources as being trustworthy and to allow data transport originating from said trustworthy data sources to pass through without monitoring.
