An Audio Watermarking Based on Discrete Cosine Transform and Complex Cepstrum transform

摘要：

Digital audio watermarking is an efficient way of copyright protection. A robust watermarking was proposed based on Discrete Cosine Transform and Complex Cepstrum. Special steps are done to enlarge the capacity. And watermark information can be embedded by quantization. So it is blind in extracting progress. The experiments show that it is robust against attacks.
