Patent ID: 8495086

Claim:
A method for verifying that musical recordings having a background musical soundtrack and at least one secondary musical soundtrack including vocal music are licensed comprising: distinguishing said background musical soundtrack from a secondary musical soundtrack of a licensed musical recording; taking a periodic sequence of fingerprints of a model musical recording having both model background soundtracks and model secondary vocal soundtracks; taking said same periodic sequence of fingerprints of only said background musical soundtrack; comparing the periodic sequence of background musical soundtrack fingerprints with said sequence of model musical recording fingerprints for matching fingerprints; storing the sequential points of matching fingerprints as the sequence for mapping the background musical fingerprint pattern; storing the sequential points of non-matching fingerprints as the sequence for mapping the secondary vocal musical fingerprint pattern; storing said background musical fingerprint patterns and said secondary musical fingerprint patterns in a database of licensed musical recordings; sequentially comparing a musical recording under test to determine whether the recording under test is licensed to said stored background and secondary musical fingerprint patterns; and indicating a non-licensed musical recording upon a failure in said comparison.
