XML Document Information Hiding Based on Sub-element Permutation and Combination
Rui Xiong-li · Jisuanji gongcheng · 2009
This paper analyzes the hiberarchy of eXtensible Markup Language(XML) document.Based on XML sub-element permutation and combination,an information hiding algorithm is presented.This algorithm changes secret information to a decimal integer and creates equal element by permutation and combination of sub-element.According to mapping relation between equal element and integer,the integer is embedded into the XML document by changing the element to its equal element.Experimental results and analysis show that the algorithm does not change the size of XML document,and has better imperceptibility and robustness and larger information hiding capacity than existing XML document hiding techniques.The algorithm can be used to protect the content of a XML Web page and covert communication.
