基于回声隐藏的VDSC隐写分析算法
摘要
基于回声隐藏改变自然语言倒谱分布这一特点
提出了一种新的针对回声隐藏的隐写分析算法。该算法无需估计隐写分段大小
通过构造倒谱和差分方差统计量VDSC(variants of difference of sum of cepstrum)来反映隐写对自然语音音频的影响
从而判定该文件是否为回声隐藏文件。实验结果显示
该算法正确率为88%。
Abstract
Based on the idea that echo hiding changing the cepstrum distribution of natural audio
a new audio steganaly-sis method was presented.The VDSC(variants of difference of sum of cepstrum)was constructed to decet echo hiding audio files without estimating the size of hiding fragment.Experiment results show the accuracy of detecting echo hiding audio files is 88%.
