XML中的信息隐藏

Information Hiding in Extensible Markup Language (XML)

XML作为Internet上的信息交换格式,XML(Extensible Markup Language,可扩展标记语言)一出现, 使得到广泛的应用和支持,它将掀起新一轮数据处理和网络应用开发的革命.XML不是一种普通的文本语言,它用于置标电子文档,是一种使其数据具有结构化的置标语言.利用XML的这一特性,可以将秘密的信息隐藏到XML文本中. 这种方法主要是基于XML不是一种普通的文本文件,而是一种结构化的丈本.通过改变XML的标示字体的物理特性, 或变换DTD声明及其应用能量中的原始XML文档的逻辑结构,将信息隐藏到XML的原始文档中.

As a kind of information transaction format, XML() has been used and supported widely. It will bring a new revolution of data processing and network development. XML is not only a kind of normal text language, but also a markable electronic document and also a markable language for the structured data. With this characteristic, some secret information could be input into the XML text. This kind of method of information hiding was based on the theory that XML was not a kind of notmal text file but a kind of structured text. The information could be hiden into the original document by altering the physics characteristic of the markable font or changing the DTD statement and applications energy logic structure of the original XML document.
