Abstract:
1. A computer-implemented method of identifying a source of media, comprising: performing the following actions using at least one computer: identifying a plurality of segments arranged to form said media; generating a representative master key (RMK) of said media from the arrangement of the plurality of segments, wherein the RMK comprises a first listing of master identifiers corresponding to the plurality of segments, each master identifier of the first listing of master identifiers identifying a source master of each segment of the plurality of segments; receiving a listing of fingerprints, each fingerprint of the listing of fingerprints having a corresponding identifier that identifies the source of said media, said each fingerprint also including a second listing of master identifiers; comparing the first listing of master identifiers in the RMK to the second listing of master identifiers in said each fingerprint in the listing of fingerprints to identify the source; generating a first plurality of key sets from the RMK, wherein a key set is an arbitrary number of tuples formed as a subject of the RMK, wherein the arbitrary number is less than or equal to the number of segments in said media, and wherein a tuple comprises a pair of numbers which identifies a segment number and a corresponding master identifier; generating a second plurality of key sets from said each fingerprint; and comparing the first plurality of key sets to the second plurality of key sets.
