| 摘 要： | 数字水印技术作为版权保护的重要手段,已经得到了广泛的研究和应用。它可以被看作带有辅助信息的通信机制的一种特殊形式,文章基于这种机制提出了一种稳健的数字音频水印算法,嵌入后的音频信号与原始信号在感知上是相似的。利用均值滤波处理,算法在水印的检测过程中不需要使用原始信号,实验表明该算法对通常的音频信号处理,如音频压缩、低通滤波等,具有较好的稳健性。

| Abstract: | As a main method for copyright protection,digital watermarking techniques have been widely studied and applied.It is seen as a special form of communications with side information mechanism.This paper proposes a robust digital audio algorithm based on the mechanism.The audio signal embedded watermark is perceptually similar to the original one.Employing mean filtering process,the algorithm doesn't require the use of original signal for watermark detection.The experimental results show the algorithm is robust against common audio signal processing such as mp3audio compression,low-pass filtering,etc. |
