A method of using only the audio track, for automatically implanting (in both forward and reverse printing) sequential identification film numbers as an integral part of the film, (both new and existing), with no change to the film or printing process and which is unnoticed by the viewer or listener. Any copy (direct print or broadcast) of such film will bear the exact same traceable identification number. The many applications comprise: proof of broadcast and cable transmission for programs and commercials; royalty data:movies, juke boxes, etc.; residuals data for musicians and actors; apprehension of illegal copiers.
