摘　　要：提出了一种基于差分直方图的LSB图像隐藏信息盲检测技术。该算法的基本思想是在分析和提取图像差分直方图统计特征的基础上,采用随机假设检验方法检测隐藏信息嵌入概率,从而实现图像隐藏信息的盲检测。仿真实验结果表明,该算法在提高检测速度的同时,能有效降低盲检测的虚警率和误报率。A blind detection algorithm of LSB image hiding information is proposed based on difference histogram in this paper. The detection of the embedding rate of information hiding with stochastic hypothesis prove method is the general consideration of the algorithm for accomplishing blind detection course on the premise of analyzing and extracting image of difference histogram statistic characteristics. It was shown by the simulation tests that the algorithm reduced the blind detection＇s false alarm rate and misinformation rate while improved the average detection speed.
