基于改进亚仿射变换的图像信息隐藏算法
Image Information Hiding Algorithm Based on Improved Sub-affine Transformation
摘要
Abstract
An information hiding algorithm of image fusion technology is proposed based on the improved sub-affine transformation.This algorithm preprocesses the secret information image by using the improved sub-affine transformation, increases the key of the original algorithm from six to eight, and completes hiding secret information by using image fusion technology based on Logistic chaos sequences.Experimental results show that sub-affine transformation has good scrambling effect and safety level, and Logistic chaos sequence which enhances the security of image hiding compared with traditional hiding algorithm's blend factors have larger space.关键词
