Robust Audio Watermarking for Copyright Protection

A new method for embedding digital watermarks into audio signals in the time domain is presented． This method makes use of good properties of chaotic sequences，such as ease of generation，sensitive dependence on their initial condition and noise-like statistic characteristics．The watermark embedded can be extracted without the knowledge of original audio signals．Experiments show that our watermarking scheme leads to results with good audio quality and is robust to withstand most of the common signal processing．
