| 摘 要： | 数字图像分存技术将一幅秘密图像分解成几幅无意义或者杂乱无章的图像进行存储或传输,获得其中部分分存信息就能恢复出原始图像信息,以便增加图像信息的安全性.文中提出了一种基于图像分存和离散小波变换的的信息隐藏算法.首先利用置乱变换对传输图像进行加密,再将置乱后的隐秘信息分成N份,然后将隐秘信息随机嵌入到图像的小波分解系数中,...

| Abstract: | Digital image sharing decomposes a secret image into several meaningless or disordered images,or camouflages it into several significant and meaningful images to store or transfers in order to enhance the security of the image information.When some parts are known,the original information can be recovered.This paper introduce a Method for Image Hiding Based on Information Divided-storage using Discrete Wavelet Transformation.Using the scrambling transformation to encry the image,and then the secret informat... |
