基于坐标轴的双重置乱数字图像隐藏算法与实现

Based on the Dual Axis Digital Image Scrambling Algorithm and Implementation Hiding

近些年来,通信技术的发展,尤其是随着由通信领域和计算机领域相结合而产生的计算机互联网络的普及及应用,使信息的共享与传播日益频繁。信息共享在给人们带来种种便利的同时,也带来了一系列的信息安全问题,如信息窃取的问题、版权保护的问题、信息篡改等问题。数字图像信息隐藏技术是一种图像信息保护技术,综合该领域的已有研究,提出了一种基于坐标轴的、通过双重置乱的算法,将图像隐藏得安全,抗攻击性更强,且恢复质量更好,恢复操作方便。

In recent years, the development and popularization of communications technology field, especially, with the popularization and its applications of computer network which generated by the combining of communication field and computer field, make data information sharing, communication are ever increasingly frequent. So it gives people a myriad of convenience, but also brings a series of derivatives data and information security such as data information stolen problem, the protection of the copyright problem, data information tampering problem. Digital image information hiding technology is a kind of image information protection technology. With comprehensive research of this field, this paper puts forward on the coordinate, through the dual stronger, making recover quality better, scrambling algorithm, making a method based image hiding more security, making fighting offensive and recovery operation is convenient
