提出了一种新的倒谱域音频信息隐藏方法。音频的倒谱表示可以被证明对各种各样的攻击非常鲁棒，包括最具挑战性的时间缩放和音高偏移变形。在倒谱域中，我们建议通过操纵所选倒谱系数的统计平均值来嵌入数据。一个直观的心理声学模型来控制引入失真的可听度。实验结果表明，该算法在20 bps以上的容量范围内实现了透明的、鲁棒的音频信息隐藏。
We propose a novel data hiding scheme for audio signals in the cepstrum domain. Cepstrum representation of audio can be shown to be very robust to a wide range of attacks including most challenging time-scaling and pitch-shifting warping. In the cepstrum domain, we propose to embed data by manipulating the statistical mean of selected cepstrum coefficients. An intuitive psychoacoustic model is employed to control the audibility of introduced distortion. Our experiment results have shown that the novel audio data hiding scheme in the cepstrum domain can achieve transparent and robust data hiding at the capacity region of above 20 bps.
