| 摘 要： | 提出了一种基于分抽样的音频数字水印算法。该方法对音频信号进行分抽样,然后把水印信号嵌入子音频信号的小波变换后的低频系数中。水印提取时不需要原始音频信号。实验结果表明,该算法对一般的信号处理具有一定的鲁棒性。

| Abstract: | A subsamplebased watermarking scheme has been investigated for digital audio in this study.The audio signal is subsampled and the watermark information is embedded into low frequency coefficients of the subaudios after DWT.The extracting procedure reverses the embedding operations without the reference of the original audio and provides a better copyright protection scheme.Experimental results show the algorithm is robust to signal processing. |
