Abstract:
1. An apparatus that determines an identity of an unknown sampled work, said apparatus comprising: a database to store 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, wherein said predetermined hop size of each of said plurality of segments of said unknown sampled work is less than said known hop size; and a processor coupled to the database to receive data of said unknown sampled work, to segment said data of said unknown sampled work into a plurality of segments wherein each of said segments has a predetermined segment size and a predetermined hop size, to create a plurality of signatures of said unknown sampled work based upon said plurality of segments of said unknown sampled work, wherein each of said plurality of signatures is of said predetermined segment size and said predetermined hop size, to compare said plurality of signatures of said unknown sampled work to a plurality of reference signatures of each of a plurality of reference works created from a plurality of sample segments of each of said plurality of reference works, each of said plurality of reference signatures of each of said plurality of reference works having a known segment size and a known hop size wherein said predetermined hop size of said each of said plurality of segments of said unknown sampled work is less than said known hop size, and to identify said unknown sampled work is one of said reference works based upon said comparison.
