| 摘 要： | 通过分析SPA(sample pair analysis)算法的检测原理,提出了一种抗SPA分析的信息隐藏方法.该方法根据载体图像的统计特性,按计算的比例混合使用两种替换方法来嵌入信息,使得SPA算法的检测值趋于最小.实验结果表明,该方法在信息嵌入时可以调节载体图像的统计特性,不仅可以有效地抵抗SPA算法,而且对其他隐藏分析算法也很有效.

| Abstract: | A steganographic scheme against SPA algorithm was proposed by analyzing the detection principle of SPA.According to the statistical property of a cover image,the proposed method calculated the rates of two different replacing methods which were used alternately to make the detection value of SPA tend to zero.The experimental results show that the proposed method can adjust the statistical property of the cover image during the information embedding process,which makes steg-images resist SPA and RS algorithms effectively. |
