基于Lorenz的彩色图像隐藏算法研究
摘要
在空域图像隐藏算法中
盲提取方法一直被认为是达到最佳隐藏效果的重要环节.鉴于此
提出了一种基于Lorenz的彩色图像的信息隐藏算法.采用一种将混沌和信息高位隐藏相结合的盲提取算法
该算法是将秘密信息按某一混沌序列存放在载体图像的高位
提取时无需原始图像即可实现信息的提取.实验结果表明:提取出的秘密信息完整清晰
该算法具有隐藏容量大(60%)
隐藏速度快(0.425 s)
抗非法提取
不可见性好等特点.
Abstract
In the spatial domain image information hiding algorithm
the blind extraction method is regarded as an important step to reach perfect hiding effect.Here a Lorenz-based information hiding algorithm for color images is proposed.The algorithm adopts a blind extraction method combining chaos and information high bit hiding.According to the chaos sequence
secret information is hided in the carried image high bit.The extraction process can be realized without original image.Experimental results indicate that the secret information extracted is integrity and clarity.The algorithm has advantages of large hiding capability(60%)
fast hiding speed(0.425 s)
illegal extraction resistance and good invisibility.
