In this paper, we propose a statistical audio watermarking scheme based on DWT (Discrete Wavelet Transform). The proposed method selectively classifies high frequency band coefficients into two subsets, referring to low frequency ones. The coefficients in the subsets are modified such that one subset has bigger (or smaller) variance than the other according to the watermark bit to be embedded. As the proposed method modifies the high frequency band coefficients that have higher energy in low frequency band, it can achieve good performances both in terms of the robustness and transparency of watermark. Besides, our watermark extraction process is not only quite simple but also blind method.
