| 摘 要： | 为了有效提高图像隐藏的鲁棒性和安全性,文章提出一种基于混沌置换的图像隐藏算法。该方法采用混沌置换算法,能以概率1产生所有置换,优于传统置乱算法。该方法重复隐藏了冗余信息,能较好地抗击噪声干扰和剪切攻击,具备线性时间复杂度。实验结果表明,该方法隐藏效果良好,恢复图像保真度高,具备较好的鲁棒性和安全性。

| Abstract: | By blending pixels into different places,an image information hiding algorithm with linear time complexity is proposed.Based on the chaotic permutation,the method is proved that it can extend all over the permutations with probability 1,and the traditional permutation turns out a special case of chaotic permutation.Examples show that the algorithm is efficient and robust against noise corruption and shear attack. |
