| 摘 要： | 文章提出了一种基于频率掩蔽效应的自适应音频数字水印算法。嵌入的水印为视觉可辨的二值图像,水印能根据音频信号的频域掩蔽阈值进行自适应调整,水印的提取采用假设检验的方法。实验结果表明所嵌入的水印是不可感知的,该算法对大多数音频信号处理具有很强的鲁棒性,如重采样、MP3压缩和随机裁剪等操作。

| Abstract: | An adaptive audio digital watermarking method based on frequency masking is proposed in this paper.The watermark embedded in this algorithm is a significant binary image and adaptively embedded according to frequency masking threshold of audio signal.The watermark can be extracted by hypothesis test.The experimental results show that the watermark embedded is imperceptible and the algorithm is robust to many attacks,such as,resampling,MP3compression,random cutting and so on. |
