摘　　要：采取小波变换的方法对载体图像和秘密图像进行分解,并将分解后的秘密图像信息进行混沌置乱,再采用图像融合的方法完成对秘密图像的隐藏。使用MATLAB工具对图像隐藏算法进行了实践,实验数据体现出该算法具有较小的失真度、良好的不可见性和安全性,同时该算法还提高了含密图像的不可感知性以及秘密图像的鲁棒性。An information hiding algorithm based on chaotic scrambling and image fusion was proposed and put into practice.The method of wavelet transform is adopted to decompose the carrier image and secret image,and the decomposed secret image information is chaotic scrambled.Then,image fusion is used to hide the secret image.The image hiding algorithm was practiced using MATLAB tools,and experimental data showed that the algorithm has low distortion,good invisibility,and security.At the same time,the algorithm also improves the imperceptibility of encrypted images and the robustness of secret images.
