System and method for monitoring unauthorized transport of digital content
First Claim
1. A system for network content monitoring, comprising:
- 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, and 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.

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.

69. A system for network content 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 payload of said monitored data, said derivation being indicative of content of said data, a database of preobtained signatures of content whose movements it is desired to monitor, a comparator for comparing said derivation with said preobtained signatures, thereby to determine whether said monitored data comprises any of said content whose movements it is desired to control, a decision-making unit for producing an enforcement decision, using the output of said comparator, and a bandwidth management unit connected to said decision-making unit for managing network bandwidth assignment in accordance with output decisions of said policy determinator, thereby to control content distribution over said network.

109. A method of monitoring for distribution of predetermined content over a network, the method comprising:
-
obtaining extracts of data from at least one monitoring point on said network, obtaining a signature indicative of content of said extracted data, comparing said signature with at least one of a prestored set of signatures indicative of said predetermined content, using an output of said comparison as an indication of the presence or absence of said predetermined content.

-
110. A method of controlling the distribution of predetermined content over a network, the method comprising:
-
obtaining extracts of data from at least one monitoring point on said network, obtaining a signature indicative of content of said extracted data, comparing said signature with at least one of a prestored set of signatures indicative of said predetermined content, using an output of said comparison in selecting an enforcement decision, and using said enforcement decision in bandwidth management of said network. - View Dependent Claims (111, 112)
