摘要/Abstract

摘要： 针对目前多数信息隐藏算法的安全性不高使其无法应用于隐蔽通信等领域的问题,提出了一种基于游程长度的隐藏算法,算法的基本思想是将图像分解成多个二值图像,通过对分解后的二值图像游程长度的奇偶性来隐藏信息,最多改变二值图像黑白交界处的一个像素值便可隐藏1bit的信息,隐藏信息可实现盲提取。算法未造成图像低位平面的0和1分布特性的明显改变,也未造成长游程的减少,因此可抵御许多针对LSB及其改进方法的隐写分析技术的检测。仿真试验结果显示,算法的安全性高,不可感知性好,并且嵌入容量大,可应用于隐藏通信等对隐藏容量和安全性有较高要求的场合。

Abstract: Aiming at the problem that most information hiding algorithms are not secure enough to afford secret communication,a kind of hiding information algorithm based on Run Length was proposed．The main idea of this algorithm is separating the image into several binary images．Through utilizing the parities of the Run Length of the binary images,one bit of information can be successfully embedded while even one pixel that is located along black-white boundary of the binary image is modified．The blind extraction of the hiding information can be achieved．The algorithm neither obviously changes distribution property of 0and 1in image’s low plane,nor reduces the Length of Run．Hence it can defend various detections against LSB and its improved method．The simulation result shows that the algorithm has high security,good imperceptibility and large embedding capacity．Furthermore,it can be applied in secret communication and other situation that requires high security and large capacity.

Key words: Information hiding,Run-length,Embedding capacity,Imperceptibility,Security
