用于版权保护的鲁棒音频水印

提出一种将数字水印在时间域上嵌入到数字音频信号中的方法，该方法利用混沌序列具有容易生成，对初始条件敏感，以及具有白噪声的统计特生等特点，水印的抽取不需要原始音频信号的知识，实验结果表明，该方法能够保证好的音频信号质量并对大多数普通信号处理具有鲁棒性。

Robust Audio Watermarking for Copyright Protection

A new method for embedding digital watermarks into audio signals in the time domain is presented. This method makes use of good properties of chaotic sequences, such as ease of generation, sensitive dependence on their initial condition and noise like statistic characteristics. The watermark embedded can be extracted without the knowledge of original audio signals. Experiments show that our watermarking scheme leads to results with good audio quality and is robust to withstand most of the common signal processing.
