摘要:
 
随着互联网和通信技术的飞速发展,计算机网络信息化等方面的发展对信息安全技术提出了越来越高的要求.电子文档已成为储存及传送信息的最常用载体,计算机泄密问题随之产生,且更具隐密性、潜伏性和危害性,同时也增加了失泄密问题预防难度.Office 2007文档采用了一种新的默认文件格式,即Office Open XML格式,为在Office文档中隐藏信息提供了新的思路.为此,结合Office文档的自身特点和XML格式规范,提出了一种符合Office XML格式规范的信息隐藏方法.该方法针对DOCX、PPTX和XLSX三种不同类型格式文档,匹配与格式相对应的特定属性,选取或构建包含该属性的XML段落,通过替换或构造特有的标识属性值将隐秘信息嵌入目标文本载体中,以实现信息隐藏的目的.实验结果表明,该方法使用文本容量大,安全性高,较好地解决了现有方法鲁棒性不足的问题.
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.
