通过缩放字符比例在Word文档中隐藏信息的算法研究

信息隐藏技术既隐藏信息的内容又隐藏信息的存在,它作为确保计算机网络信息安全的一个重要手段正成为信息安全领域的研究热点之一。对改变文字大小在Word文本文档中隐藏信息的算法进行了改进,改进后的算法利用轻微缩放字符的比例在Word文本中隐藏信息,信息隐藏量提高到每个字符隐藏2位信息。

Study through the Algorithm that the Character Proportion of Scale Hides Information in Word File

The information hiding technique can hide the content and existing of information, and it is an important method to insure the computer network information security. It is becoming one of hot research topics in information security field. The information hiding algorithm based on modifying the size of the characters is improved by using zooming the characters tinily. This algorithm can embed 2 bit data into every character of source document.
