一种基于LSB图像信息隐藏的改进算法

摘要

介绍并分析了传统的LSB信息隐藏算法原理,详细阐述了图像置乱技术的原理和一种传统的混沌图像置乱方法.在此基础上,提出了一种新的图像信息隐藏算法:基于图像向量索引奇偶性进行信息隐藏的算法.试验结果及分析结果表明,该算法实现简单,有很好的视觉掩蔽性和较高的信息隐藏容量,并提高了信息隐藏的安全性.%The LSB is the traditional information hiding methods, At first, this paper Presented and analyzed its principle. Then elaborated the principles of image scrambling technology . On his basis, we proposed a new image information hiding algorithm, the experiment and analysis results show that the algorithm is simple, having a good visual masking, high information hiding capacity and good security.
