A robust audio digital watermarking in complex cepstrum domain based on chaos theory against STIRMARK

Digital audio watermarking is considered as an efficient way to copyright protection. A robust algorithm was proposed based on chaos theory and quantization in comlex cepstrum domain. Parameter selection is a key and unmanageable problem. In the proposed method, embedded positions and parameters (including threshold value and step length) were given. And it is helpful for improving robustness and transparency. The experiments show that it is efficient to resist famous STIRMARK attacks.
