摘　　要：在汉明码和Logistic-正弦映射的基础上,提出了一种新型的信息隐藏算法.首先用Canny边缘检测算法提取载体图像的边缘,然后用Logistic-正弦映射产生3个密钥.对秘密信息流用汉明码进行编码,并把信息流隐藏在经过置乱的载体图像的边缘像素上.为了进一步增强图像的视觉效果,采用2k修正法进行修正隐写图像.实验结果证明了本文方法的安全性、有效性和鲁棒性.A novel steganographic algorithm based on Hamming code and Logistic-sine map was proposed.Canny edge detector was applied to detect the edge of cover image.Then three keys were produced with Logistic-sine map.Then Hamming encoding was executed to code the secret data and embedded in scrambled edge pixels.Finally,the method of 2 k correction was used to achieve better imperceptibility in stego image.Experimental results showed that the proposed algorithm was excellent in security,availability and robustness.
