摘要
利用图像分存相互旋转,改变不同分存图像的对应关系的方法来进行恢复多幅秘密图像的,并且将秘密图像信息中的无实际意义的分存图像转化为有意义的分存图像,使这些分存信息在传输的过程中不容易受到黑客的攻击进而导致原秘密信息无法恢复,运用这种方法可以大大提高秘密信息的安全性.
This article proposed a method to transmit and restore images secretly by means of mutually rotating the images,and changing the corresponding relationship between different images.The secret images without meaningful information were convert into meaningful images.The information in the transmission is not easy to ba attacked by hackers,which may lead the original secret information unrecoverable.This method can greatly improve the security of secret information.
