摘    要:基于新的Arnold反变换提出了对公开图像进行置乱变换的信息隐藏算法。算法一反常规地不是对秘密图像而是对公开图像实施置乱预处理。首先对公开图像进行Arnold变换,然后对变换后的公开图像分块进行DCT,在低频部分嵌入秘密信息,最后运用新的Arnold反变换恢复原图。这样大大减少了运算量,极大增强了信息的安全性,攻击及对比实验充分表明了此算法的鲁棒性和有效性,也证明了新的Arnold反变换的优势和可行性。

关 键 词:信息隐藏; 图像置乱; 新的Arnold反变换; 离散余弦变换

Abstract:This paper proposed a new algorithm of public image transformation for information hiding based on a new anti-Arnold.Firstly,transformed a public image by traditional Arnold transformation.Then a public image was divided up some blocks and transferred by DCT,hided the secret image into coefficient of lower frequency.Last recovered the public image by the new anti-Arnold transformation.So reduced the time of calculating,what's more,the security was enhanced greatly.At the end,tested its the robustness with m...
Keywords:information hiding   image scrambling   new anti-Arnold transformation   DCT (discrete cosine transformation)
