Abstract :
In this paper, a new 2-dimension audio watermarking algorithm based on integer wavelet transform is presented, in which the gray image (2-dimension digital watermark) can be embedded into the host audio signal. The features of the proposed algorithm are as follows: (1)integer wavelet transform theory is utilized to solve rounder-off error problem and to reduce computation complexity. (2)The strategy of segment transform and the whole wavelet coefficients modification is adopted to improve the robustness of the digital watermark. (3)The gray image is embedded to enlarge the watermark volume. (4)The algorithm can extract the watermark without the help from the origin digital audio signal. Experimental results show that the proposed watermarking scheme is inaudible and robust against various signal processing such as re-sampling, re-quantization, low pass filtering, MP3 compression, and noise adding.
