Office XML Document Information Hiding Method
摘要
Abstract
With the rapid development of Internet and communication technology,the computer network pays more and more attention in information,which also emphasizes the increasing importance of information security technology. Electronic documents have become the most commonly used carrier in information storage and transmission and thus the problem of computer file leakage has generated more hidden,latent and harmful properties than other classical methods,increasing the difficulty in prevention of leakage. Since a new default file format is introduced in Microsoft Office 2007 document,which is called Office Open XML format and provides a new ideas for infor-mation hiding in Excel documents. An information hiding method based on Office Open XML file format is proposed in investigation of features of Office documents and XML specifications. With different kinds of files,such as DOCX,PPTX and XLSX,it adopts different i-dentifier attribute,which finds or creates a segment with this attribute to hide information by changing the attribute value. Experiment re-sults show that it can hide large capacity information and thus is safety with high capacity and security,which has solved poor robustness of the existing methods.关键词
