邮件文本的信息隐藏技术研究

随着信息化的发展，保密通信变得越来越重要。当今，电子邮件是人与人通信的重要工具之一，因此应用它进行信息隐藏已成为保密通信的重要研究课题。本文提出一种模式变换的电子邮件信息隐藏算法。这种算法是利用隐藏信息构造信息隐藏矩阵，利用文字模式构造模式系数矩阵，再用这两个矩阵构造隐藏矩阵，最后用隐藏矩阵对电子邮件的文字模式进行模式变换。本文还根据信息熵理论，分析了这种算法的信息隐藏容量。我们采用所提出的算法，设计了计算机程序，进行了信息隐藏实验。实验表明，我们的算法具有很好的信息隐藏效果。

The Research Of Information Hiding Technology Based On Email Text

Secure communication become more and more important with the advent of the information age. E-mail has become one of the most important tools for communication in public life today. Consequently, Information hiding technology based on E-mail plays a significant part in the field of secure communication. We present a method using pattern transformation to hide information in E-mail text. First, we build an information hiding matrix by the secret information and construct a pattern coefficient matrix by text pattern. Second, we use these two matrixes to build a hiding matrix which is in action of the text pattern transformation. In addition, we analyze the capability volume of our method by the theory of entropy. At last, we design a program based on our method. Extenneively tested, this method makes the information hiding effectively and efficiently.
