A Dual Digital Audio Watermarking Algorithm Based on LWT

摘要：

A dual digital audio watermarking algorithm based on LWT is proposed in this paper. Two watermarks were embedded into the original audio with LWT in this algorithm. A watermarking can choose embedding strength adaptively in the low frequency to protect audio copyright. Another watermarking can choose embedded position adaptively in the high frequency to play a dual protection. At the same time , being scramblled and being the chaos encryptted for watermark image to improve the safety of the algorithm. The results show that the watermark is imperceptible, the results of SNR reaches the high level; and the watermarking system still has strong robustness after the attacks of gaussian noise, low pass filtering, resample etc
