Abstract:
Identification of media content, such as audio, can be performed through use of watermarking or fingerprinting (aka content signature) technologies. Aspects of these technologies may be combined to advantageous effect. For example, in dealing with the problem of fingerprint errors arising from object distortion, operations known from digital watermarking systems can be employed.
