主要思想是从两幅图像中选取信息，然后置乱成一幅图像。

这样可以从要加密的多幅(2*n幅)图像中，按照上述思想，得到一半数目(n幅)的图像。

对得到的图像进行自适应算法的隐藏，又可以得到(n-1)幅的图像。

对(n-1)幅的图像进行Arnold变换，得到(n-1)幅的图像作为密钥，此外，密钥还有迭代次数，置乱规则，Arnold加密规则

主要缺点是Arnold的周期较大，程序的运行的时间长些，我的电脑需要８分钟，另外，Arnold只能处理方阵

图像的置乱加密算法很多，本程序中用到的置乱加密算法只是其中一种方法，仅仅提出一个多幅图像加密的思想，后期还有许多的工作要做。-　The main idea is to select information from the two images, and then scrambling into a single image.　 This can be encrypted from multiple (2* n pieces) image, in accordance with the above ideas, get half the number (n pieces) images.　, The resultant image Hidden adaptive algorithm, and can be obtained (n-1) pieces of images.　 For the (n-1) pieces of the image Arnold transformation, (n-1) as the key pieces of the image, in addition, there is the key number of iterations, scrambling rules, Arnold encryption rules　The main disadvantage is the cycle of Arnold larger, the program runs the hours are long, my computer needs 8 minutes, another, Arnold only deal phalanx　of the image a lot of scrambling encryption algorithm, the program used in the scrambling encryption algorithm is only one way just proposed the idea of ​ ​ a multiple image encryption, there are a lot of work to be done late.
