| 摘 要： | 基于听觉掩蔽效应，提出了一种在WAV格式音频信号中嵌入WAV格式音频水印的离散小波变换域高效水印算法，用Matlab7．0编程进行了水印的嵌入、提取及防盗版性能研究。仿真实验表明，该算法嵌入的音频水印具有较好的不可感知性和较强的抗版权篡夺能力，并且对诸如重新采样、低通滤波和叠加噪声等攻击具有较好的鲁棒性。

| Abstract: | A DWT domain efficient digital audio watermarking algorithm based on auditory masking effect that can be achieved in the WAV format audio signals embedded in the WAV format audio watermarking is proposed. By using Matlab7.0 programming the embedding, extraction and anti-piracy, and other properties of the watermarking process is studied. The experimental results show that the audio watermarks generated with the proposed algorithm are comparatively inaudible, and of stronger anti-copyright-usurpation ability, and robust against such signal processings as re-sampling, low-pass filtering, and noise adding. |
