Zero-Watermark Scheme Based on Audio´s Statistical Character

a new zero-watermark algorithm based on audio´s statistical character is presented. By using the audio´s statistical character, this paper consults the mean of the approximation coefficients of a one-dimensional signal and constructs the watermark sequence within the zero-watermark scheme. By this way, it is efficient to resolve the required trade-off between the robustness to certain watermark attacks and the imperceptual quality. The experimental results demonstrate that the proposed watermarking algorithm is greatly imperceptible and robust against general malicious attacks.
