基于新闻类RSS文档的信息隐藏系统

摘要

After analyzing the structure of news Really Simple Syndication(RSS) document, a new information hiding method based on news RSS document is developed. Because the order of the news items does not affect the reading of RSS document, the permutation and combination of tags modules can be used to hide information. Through the rational combination of other two selected information hiding methods based on extensible Markkup Language(XML) documents, an information hiding system using multi-methods based on news RSS document is constructed. Experimental results show that three kinds of information hiding methods are not conflict. The system has good performances in capacity, invisibility and robustness.%分析新闻类聚合内容(RSS)文档的结构,提出一种基于新闻类RSS文档的信息隐藏方法.根据各新闻 条目的先后顺序不会影响RSS文档使用的特点,利用标签模块的排列组合隐藏机密信息.同时选取另外2种基于XML的隐藏方法进行合理 组合,构建一个基于多种隐藏方法的新闻类RSS文档的信息隐藏系统.实验结果表明,排序后的3种隐藏方法不会发生冲突,在提高隐 藏容量的同时,具有较好的隐蔽性和鲁棒性.
