摘要
描述了一种基于方差及线性回归的语音隐藏信息盲检测方法。该方法用语音质量评估参数生成一个多元线性回归模型,可对可疑的语音进行隐藏信息盲检测,语音质量评估参数种类和数量,可用方差分析法预先选择。该方法经计算机模拟,对常用的变换域信息隐藏方法有较好的检测效果。
An audio steganalysis method based on variance and multivariate regression analysis, which can be exploited for audio detection, is studied. With the aid of audio quality measures a multivariate regression scheme is proposed to detect probable stego-audio. Audio quality measures are chosen based on ANOVA （analysis of variance） technique. Simulation results indicate that this method generally works well for transform domain steganographic.
