Blind digital audio watermarking based on SCS in wavelet domain

Performance of digital watermarking depends on the parameters of embedding algorithm. Most algorithms cannot give the quantitative relationship between embedding parameters and its performance. This paper proposes a flew algorithm of bind digital audio watermarking based on SCS. This algorithm can design the embedding parameters according to the requirement. The paper adds the watermark in wavelet domain and compares its performance with that in time domain against attacks of additive noise, mp3 compression and resample. Computer simulation proves that this algorithm is effective and stable.
