摘要
网络环境下,如何保障传输过程中图像信息的安全性,是目前信息安全领域的一个重要研究问题。图像置乱变换是一种重要的图像加密方法,其主要目的是将给定的图像进行搅乱,使人们无法通过人类视觉系统和计算机系统来发现原始图像所表达的真正含义。目前在图像置乱领域已提出一些很有意义的方法,本文主要对这些方法进行了分类讨论和总结,便于进一步的研究。
Image scrambling transformation is an important image cryptography to protect the security of image information in network. It is based on shitting positions or changing pixels gray. People can not gain any useful information from the scrambled image by human visual system or computer systems. In the past few years, there has been a tremendous surge of research in the area of Image scrambling, This paper is an effort to survey these techniques and to classify this research in a few broad areas.
