METHODS OF FINGERPRINT-BASED WATERMARKING OF AUDIO FILES

摘要

A new watermarking concept is presented. The method exploits audio fingerprinting in order to reuse the same watermark payloads between audio copies originating from different audio masters. This is achieved by using fingerprints of audio master to derive unique watermarking zones for its associated copies, therefore obviating the need of adding overhead synchronization bits to locate watermark positions. Thanks to a shorter watermark payload enabling a higher repetition rate of the watermark within the host media, the present methods have been validated via simulations to be robust against typical audio attacks such as MP3 compression, cropping, jittering, and zeros inserting.
