电子文档保护是信息防泄漏的重要内容。在对现有电子文档保护技术分析的基础上，提出一种基于剪贴板监控的电子文档多级保护技术。针对传统剪贴板监控在文档保护方面的不足，提出一种可获得文档路径的剪贴板监控策略；根据不同应用对文档保护的不同需求，提出一种动态可调的文档分级保护策略；基于剪贴板监控所获得信息完成对文档的实时动态保护，并设计实现相应的原型系统。实验结果表明，所提出的基于剪贴板监控的电子文档保护能够根据文档保护需求防止文档内容通过剪贴板泄露。

Protection to electronic documents is one of the most important contents to information leakage prevent. Based on the analysis to the existing technologies to protect electronic documents, this paper presents a multilevel protection technology to elec-tronic documents based on the clipboard monitoring. It puts forward a clipboard monitor strategy by which document path can be obtained. And then it puts forward a dynamic adjustable classification protection strategy for document, which can protect docu-ments dynamically according to the information which is obtained by clipboard monitoring. The corresponding prototype system was implemented. The experimental results show that the electronic document protection technology based on the clipboard moni-tor can avoid the document content leak through the clipboard according to the requirement of protection to electronic document.
