摘　　要：借助图像水印技术中的补丁算法,提出一种音频水印方案:改进的补丁算法(MPA) 该算法是基于统计检测理论,应用于音频信号的DCT域,但也可应用于DWT域和DFT域 实验结果表明。The auther Presents the modified patchwork algorithm(MPA), a statistical technique for audio watermarking algorithm in the transform(not only DCT, but also DFT and DWT),The MPA is sufficiently robust to withstand some attacks defined by SDMI. Experimental results show that the proposed watermarking algorithm is sustainable against compression algorithms as well as common signal processing manipulation attacks.
