摘要

为有效保护音频数字产品

增强其抗同步攻击能力

在小波域的基础上

提出了一种新的盲检测数字音频水印算法.先将完整音频进行三层小波分解

取其低频系数

再对每个音频帧进行三层小波分解

也取其低频系数

最后分别求出两组低频系数的平均值

并进行比较判断水印嵌入位置.嵌入水印后的音频信号与原音频信号在听觉上是相似的.实验结果表明

该方法既可增强水印的不可见性

又能抵御多种攻击

具有很好的鲁棒性和实用性.

Abstract

In order to protect digital audio products more effectively and improve the ability of anti-synchronization attack

a new blind audio watermarking algorithm based on wavelet transform is proposed.First

the algorithm do three-level wavelet decomposition to the whole audio signal and get the low frequency coefficients

then do threelevel wavelet decomposition to each audio frame and get the low frequency coefficients

finally find the watermark embedding positions according to comparing the two average values fr...
