一种基于DCT变换的音频隐藏算法研究

Algorithm Research of Audio Hiding Based on DCT Domain

提出了一种新的音频隐藏算法，即通过量化处理数字音频信号离散余弦变换（discrete cosine transform，DCT）域系数来隐藏信息，该算法在提取所隐藏的信息时不需要原始的音频信号。仿真结果表明：这种算法具有较好的鲁棒性和隐秘性。

A new algorithm of audio hiding is brought torward that is, through quantizing me DCT（discrete cosine transform） coefficients of digital audio signals to hide information. The algorithm does not need the original audio signals to extract the hided information. The experiment results show that the method has the better robustness and concealment.
