该文提出了一种基于离散小波变换的数字音频水印盲检算法。本算法选择在小波系
数的偶数点嵌入水印，将混沌理论引入到音频水印系统的研究中，利用混沌序列将一幅有意义的二值图像加密后嵌入到原始音频的DWT 域中，提取时不需要原始音频信号。仿真实验证明了算法的鲁棒性和不可感知性。
关键词:音频水印；混沌；离散小波变换；盲检测
Abstract: This article proposed a blind digital audio watermarking algorithm based on the DWT. The algorithm chose the even number of wavelet coefficient to embed watermark ,and introduced the Chaotic theory into the research of the audio watermarking system, the chaotic sequence encrypted a meaningful binary image could be embed into the original audio signal wavelet domain, the watermark can be extracted without the original audio signal. Experimental results demonstrate the algorithm is robust and imperceptible.
Key words: Audio marking；Chaotic；DWT；Blind detection
