Abstract :
This paper propose an audio digital watermarking algorithm based on the wavelet transform (WT) and the complex cepstrum transform (CCT). The algorithm realized to embed a binary image watermark into the audio signal and improved the imperceptibility of watermarks. Experimental results show that this algorithm has a better robustness against common signal processing such as noise, filtering, resampling and lossy compression.
