AbstractDepending on the application, audio watermarking systems must be robust to piracy attacks. Desynchronization attacks, aimed at preventing the detector from correctly locating the information contained in the watermark, are particularly difcult to neutralize. In this paper, we introduce resynchronization methods for audio watermarking based on the use of training sequences. These methods reverse the effect of a large class of desynchronization attacks. Simulation results con rm the eÆciency of the proposed methods.
