Description: 图像保密通信技术之Arnold变换
一、作业目的
1．利用Matlab实现数字图像Arnold变换的置乱及恢复。
2．深入学习通讯保密技术，进一步了解图像保密通讯技术。
3．向大家展示实现图像保密技术的方法和技术。
二、作业介绍
近年来，随着网络带宽和速度的极大提高，多媒体数据特别是数字图像的流传和使用越来越广。而人们对安全性和隐私的也愈发关注，图像加解密技术得到了极快地发展。在机要、军事、政府、金融和私人通信中，数字图像所占的比例越来越大，它所承载的信息的安全成为当前人们关心的焦点。如何确保基于网络的图像/视频信息的安全，是当前信息处理技术领域的亟待解决的难点和研究热点之。本次作业主要研究Matlab实现数字图像Arnold变换的置乱及恢复。
置乱技术是一种图像加密技术，它利用数字图像具有的数字阵列的特点，搅乱图像中像素的位置或颜色使之变成一幅杂乱无章的图像，从而达到无法辨认出原图像的目的，可用于数字图像水印的预处理和后处理过程。置乱过程不仅可以在数字图像的空间域上进行，还可以在其频率域上进行。常见置乱方法有Arnold变换、幻方变换、Hilbert曲线、Conway游戏、广义Gray码变换、仿射变换、正交拉丁方变换等。
