Patent ID: 8086445

Claim:
A method for determining an identity of an unknown sampled work, said method comprising: receiving, by a computer system, data of said unknown sampled work; segmenting, by the computer system, said data of said unknown sampled work into a plurality of segments, said segments having a predetermined segment size and a predetermined hop size; creating, by the computer system, a plurality of signatures wherein each of the plurality of signatures is a signature of one of said plurality of segments and wherein each of said plurality of signatures is of said predetermined segment size and said predetermined hop size; comparing, by the computer system, said plurality of signatures of said unknown sampled work to a plurality of reference signatures of each of a plurality of reference works wherein said plurality of reference signatures of each of said plurality of reference works are created from a plurality of segments of said each of said plurality of reference works having a known segment size and a known hop size and said predetermined hop size of each of said plurality of segments of said unknown sampled work is less than said known hop size; and identifying, by the computer system, said unknown sample work responsive to said comparison of said plurality of signatures of said unknown sampled work to said signatures of said plurality of reference works.
