摘　　要：针对RS分析、SPA分析和基于图像质量评估的盲检测分析,给出了一种抗统计分析的高嵌入效率信息隐秘传输方法。该方法利用数字位置信息构造嵌入矩阵,在所选嵌入位置的2n比特宿主数据中嵌入n比特秘密信息,最多只需修改[n/2]比特的宿主数据;结合修改位置的邻域信息嵌入,保持良好的统计特征。实验结果表明,高嵌入效率信息隐秘传输方法,获得了预期结果,能较好地应用于图像和流媒体信息为宿主的隐秘传输。Regular singular （RS） analysis, sample pair analysis （SPA） and steganalysis by using image quality metrics are powerful steganalytic techniques. A novel high embedding efficiency covert communication method against statistical analysis is proposed. The method constructs embedding matrixes by using the digital-position information. The n bits secret messages can be embedded in 2n bits host information, while no more than [ n/2 ] bits host information needs to be modified. It also has good statistical properties by using the adjacent area information of revisal position. Experimental results show that the approach achieves good performance for avoiding steganalytic techniques. It is used for covert communication of images and other stream media.
