Summary:This paper focuses mainly on using chaos encryption to protect AVS audio efficiently. A novel digital watermarking approach is introduced for audio copyright protection. A meaningful gray image embedded into digital compressed audio data is researched by quantizing MDCT coefficients (using integer lifting MDCT) of audio samples based on chaotic map. The proposed watermarking algorithm can extract the watermarking image without the help from the original digital audio signal. The experimental results show that the proposed digital watermarking approach is robust to the audio degradations and distortions such as noise adding, compression, low pass filtering, resampling, and re-quantization. The digital watermarking scheme is able to provide a feasible and effective audio copyright protection.
