1. Method for identifying and filtering multimedia data on a data transmission network, characterized in that it includes the following stages:
- a) monitoring off-line the multimedia data related to reference multimedia data, with the following stages;
a1) calculating the original fingerprints of the reference multimedia data,a2) storing original reference fingerprints calculated in a fingerprint database,a3) searching for multimedia data on the network and downloading suspicious data,a4) calculating suspicious fingerprints of suspicious multimedia data,a5) checking suspicious fingerprints against original fingerprints and classifying suspicious fingerprints into classes of similar fingerprints,a6) generating formal data with priority allocation by fingerprint class and storing formal data in a formal activation database,a7) intermittently populating at least one on-line intervention module on the network with an at least partial copy of the formal activation database,b) carrying out at least one of the following operations using said on-line intervention module;
b1) intercepting on-line the multimedia data recognized using the formal data in the formal activation database and deciding whether to allow the multimedia data recognized to pass or to block it,b2) querying on-line the multimedia data recognized using the formal data in the formal activation database and at least recording or storing the multimedia data recognized, or triggering an alert when the multimedia data is recognized,b3) listening on-line to multimedia data recognized using the formal data in the formal activation database and at least recording or storing the multimedia data recognized, or triggering an alert when the multimedia data is recognized.

Abstract
The method for identifying and filtering multimedia data consists of monitoring off-line, on a data transmission network, multimedia data with reference to reference multimedia data and using an on-line intervention module to intercept, query or listen to the multimedia data recognized on-line using formal data stored in a formal activation database generated during off-line monitoring using suspicious data obtained during a search for multimedia data on the network.
