| 摘 要： | 提出一种基于听觉掩蔽模型的音频数字水印算法，根据掩蔽阚值量化音频经DCT变换后的低频系数来嵌入水印。实验结果证明所嵌入的水印具有很好的不可感知性，对加白噪声、低通滤波和重采样等各种攻击具有良好的鲁棒性。

| Abstract: | Digital audio watermarking embedding algorithm based on auditory masking model is proposed,embedding watermarking by quantizing low-band coefficients of DCT transformation based on masking threshold.The experiment results show that the embedded watermark is inaudible,and has good robustness against kinds of attacks such as white noise,low-pass filtering and re-sampling. |

| Keywords: | audio watermarking masking model quantization robustness |
