摘要
随着计算机技术与密码学的发展,一般的加密方式越来越容易遭到破解。根据人眼对色彩的敏感度感知公式I=0.3R+0.59G+0.11B,可知人眼对颜色敏感度依次为绿红蓝,文中采用最低有效位算法,结合DES加密,用需要加密的信息对24位图片RGB的最低位进行置换,实现了信息在数字图像中的隐藏。信息加密后,数字图像从肉眼上无法区分,可有效避开攻击者的注意力,保障了信息的机密性。
In order to satisfy the requirement of the modem cryptology and information security, a professional logistics Digital image hiding processing technology based on LSB sequence is proposed in this paper. According to the sensitivity of the human eye to color sensitivity ,we replace the lowest bit of he RGB of the 24 images realizing the effective hiding of information. After Information encryption, we can not distinguish digital images from the naked eye,protecting the confidentiality of information.
