基于XSLT的XML文档信息隐藏方法研究

XML文档具有存储与显示分离的特性，利用XSLT可以将同一篇XML文档显示出不同的内容，这样就可以实现隐藏信息的目的。通过研究XML的样式表转换，提出了基于XSLT的内容抽取、内容比较、样式表合并的三种XML文档信息隐藏方法，每种隐藏方法利用了样式表元素的不同性质，并通过实例对进行具体介绍和分析。上述三种隐藏方法主要针对文档的显示特性，不对文档存储的格式和内容做任何改动。实验结果表明，利用样式表转换的方法在XML文档中隐藏信息具有实现简单、安全性高的特点。

Research on Information Hiding in XML Document Based on XSLT

The storage and display of XML document is separated. The same XML document can be displayed with different contents by using XSLT, through which information hiding can be achieved in XML. XSLT is studied and three information hiding methods such as contents extracting, contents comparing and style sheets combining in XML document XSLT-based are proposed. Each method makes use of different nature of style sheet elements, and is introduced with specific example in detail. Three hiding methods are for the properties of document display, and will not make any changes to the document format and content. The experiment results show that these methods are implemented easily and have good performance in security.
