| 摘 要： | 给出了一种基于混沌序列的多幅图像隐藏算法.利用图像的迭代混合可以将多幅图像隐藏于一幅图像之中,借助Logistic混沌动力学系统过程既非周期又不收敛,且对初始条件敏感性,产生实数值混沌序列,作为隐藏算法的混合因子,提高了隐藏算法的安全性;为了进一步提高图像隐藏的安全性,对待隐藏图像进行基于象空间的置乱处理.实验结果证明,算法简单易行,安全性好.

| Abstract: | An algorithm of multiple digital image information hiding is presented.Based on chaos sequences,multiple digital images can be hidden into another by using iterative blending.With the help of Logistic chaos dynamics systematic process which is non-period,non-convergence and sensitivity to the initial conditions,the real chaos sequence is produced,being the blending factor of the hiding algorithm,which improves the security of the hiding algorithm.In order to improve the security of image hiding,the hided image should be dealt with scrambling based on pixel space.The numerical experimentations show that the hiding algorithm is efficient and safety. |
