三维混沌映射和位信息处理的图像隐藏算法

构建一种基于三维混沌映射和位信息交换处理相结合的图像隐藏方法,将原始图像的高低Bit位进行交换,进而和Qi映射形成的3个维度上混沌序列截断矩阵进行异或处理,完成图像信息隐藏.实验结果表明:所提出的方法具有良好的视觉隐藏效果,隐藏后的图像在3个方向上的相关性非常低,并且对微小的密钥变化也非常敏感.

Image Hiding Algorithm Based on 3D Chaotic Mapping and Bit Information Processing

A method of image hiding based on 3D chaotic map and bit information exchange is constructed. This method exchanges the original image of the high and low Bit and Qi mapping form the three dimensions of the chaotic sequence truncation matrix of XOR processing to complete the image information hiding. Experimental results show that the proposed method has good visual hiding effect, and the correlation between the hidden images is very low, and it is also very sensitive to the minor key changes.
