Abstract: The paper proposes an information-hiding method based on the structure of XML, based on analysis of the data structure of XML file. The secret data is preprocessed, then according to the structure of the elements, the secret data is hided by replacing the element name with thesaurus. Experimental results prove the method is easy to implement, and has high expansibility and high security.

摘要： 分析XML的文件结构，提出一种基于XML的信息隐藏方法。对待隐藏信息进行预处理后，按照文件中元素的结构，通过对文件中的元素名称进行同义词替换来实现信息隐藏。实验表明，该方法实现简单，有较好的可扩展性和较高的安全性。
