| 摘 要： | 提出一种数字图像分存方法,首先构造可逆矩阵,并通过矩阵运算直接将秘密图像分解成几幅等大小的置乱加密图像,然后分别将它们伪装在几幅经过放大且有意义的载体图像中,实现了图像分存,文中将置乱加密、信息隐藏、分存技术三者有机结合,整个算法实现简单,运算量小,数据膨胀率低,安全性高,秘图恢复效果较好,大量实验也验证了算法的有效性。

| Abstract: | This paper presents a new method of digital image sharing.Firstly,construct a reversible matrix,decompose a secret image into several scrambling and eneryption images at one time by matrix operation,then camouflage them into several megaseopie and meaningful cartier images to store or transfer.This algorithm combines the scrambling technique,encryption technique,information hiding and sharing technique,but with much simpler algorithm,less computation time,smaller pixel expansion,better recovery effect.The results show that the algorithm has application value in the field of secret image storage and transmission. |
