Abstract :
In this paper, a technique for temporal embedding of a multibit watermark on an audio signal is proposed. The method is based on generating a chaotic sequence which is used for modifying the audio samples. A chaotic sequence generates the watermark, while the parameters of the embedding procedure are chosen so as to minimize the perceivable distortion of the initial signal, while preserving the power of the watermark at a detectable level. The watermark is resistant to lowpass manipulation attacks, such as filtering or compression, and cropping attacks as well.
