摘　　要：文章提出了一种新颖的把隐藏信息嵌入预选图像,通过N维Arnold置乱预选图像实现信息加密,并对载体图像进行DCT变换嵌入置乱图像的信息隐藏算法。主要包括N维Arnold图像置乱、信息的嵌入与提取算法。利用matlab6.5平台进行了算法实验,实验的结果表明该算法具有较强的隐蔽性和鲁棒性,其隐藏信息量大,信息类型多,因此在internet通信领域中具有较高的使用价值。This paper proposes a kind of novel information hiding Algorithm based on N dimensions Arnold and DCT transform. The encryption method, which transforms information into color image and employs N dimensions Arnold to scramble the color image is designed, it implements DCT transform on the carrier image in order to embed the scrambled image. It mainly includes N dimensions Arnold scrabbling image, the message embedding and extracting algorithm, Algorithm experiments are carried out with matlab6.5. The experiment results show that the algorithm is of strong concealment and robustness, and can hide a great number of information and various kinds of information, It is of higher value in Internet communication.
