基于格式化文本颜色的安全增强信息隐藏方法

随着办公自动化的日益普及,文本成为信息存储和传输的重要载体,基于文本的信息隐藏技术凸显研究价值。针对文本的信息隐藏方法存在隐藏容量小、安全性低的特点,提出了基于格式化文本中字体RGB颜色值的安全增强信息隐藏方法,依据Kerckhoffs准则和康托展开式设计了隐藏信息的编码方法和信息隐藏过程,分析了该方法的使用条件、隐藏容量、安全性和适用性。通过实验验证,该方法具有较好的信息隐藏容量,适用范围广泛且具安全性较强,具有一定的实用价值。

A Security Enhanced Information Hiding Method Based on Formatted Text Color

With the increasing popularity of office automation, text has become an important carrier of information storage and transmission. According to the features of small capacity and low security for text information hiding methods, the paper put forward the new safety enhanced formatted text information hiding method based on Kerckhoffs criterion and Cantor expansions. The encoding method of hiding information and the whole information hiding process were designed. And also the condition, hiding capacity, safety and applicability of the method were analyzed. The experimental results show that the proposed method has better information hiding capacity, higher security and wider scope of application.
