摘要
提出一种基于听觉掩蔽模型的音频数字水印算法,根据掩蔽阈值量化音频经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。
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 resampling.
