Arnold算法图像信息隐藏技术MATLAB仿真
摘 要：图像信息作为文件传输中的主要载体，具有直观性、信息量大等优点，有些涉及军事安全、个人隐私等。这些图像一旦被截获，将存在很大的安全隐患，因此，如何保证图像安全的到达接收方是一个很重要的研究课题，图像隐藏技术能够很好的解决这一问题。图像置乱技术作为信息隐藏的一种重要技术被越来越多的学者重视，并涌现出了大量的算法。本文介绍了图像信息隐藏的历史和现状，主要罗列了信息隐藏中的数字水印和图像置乱算法，重点研究了图像置乱算法中的Arnold转换，并对该算法实现了MATLAB仿真。

Research on Image Information Hiding Technology
Abstract: As the main carrier in the file transmission, the image is intuitive and contains a large amount of information and other advantages, in addtion, some images may involve military security and personal privacy etc, therefore, if these images once was intercepted, it will bring about great security risk. how to guarantee the image’ safe arrival to the receiver is a very important research topic, and then image hiding technology can well solve the problem. Image scrambling technology as a important information hiding technology receives more and more scholars’ attention, and emerges a large number algorithm. This thesis introduces the history and present situation of image information hiding, and describes some digital watermarking algorithm sand image scrambling algorithms in the hidden information, and then focuses on studying Arnold transform in image scrambling algorithm, finally achieves MATLAB simulation.
Key Words: Information hiding; Digital watermarking; Image scrambling; Arnold transform ;MATLAB simulation.
