摘要
本文从色度学的角度提出了一种全新的密码技术—彩色图像信息融容密码技术,即根据色度学理论,将待传输或存储的彩色图像原文和用于加密或解密的彩色图像密钥在RGB颜色空间和XYZ颜色空间中进行线性和非线性的定量变换,使颜色信息得以融容,形成难以辨认和破解的密码图,从而实现对文本、图像的传递。
A new encryption technique for color image information is proposed based on melting encryption in light of color science. Linear and nonlinear transformation of quantity are applied to the two color images in the RGB and XYZ color space, and these two color images are individually the origin color image used for transporting or storing and the color image used for encryption or decryption. Then color image information is melted to encryption map, which can＇t be identified and decryption easily. So the texts and images can be transported secretly and securely.
