摘要： 随着信息化的发展，大量机密文件以电子形式存储在计算机上，而互联网的普及使各种内部机密很容易泄漏出去，据调查高达90%的企业面临数据丢失的风险. 本文提出在机密文件中嵌入数字水印的方案，用以防止网络环境下因过失而造成电子文件泄密的意外事件. 该方案用Word插件实现水印嵌入，在局域网的网关上安装软件或部署专用设备检测水印，从而截获流出的机密文档.

Abstract: With the rapid development of information technology, a large number of confidential e-documents are stored in computers, which are prone to leakage due mainly to negligence. Surveys show that up to 90% of the companies face severe financial risks because of data loss. This paper proposes a scheme to prevent e-documents from accidental leaking. This is achieved by embedding watermarks into confidential e-documents. For Microsoft Word files, the watermarks are embedded using specially designed plugins. Confidential documents that carry watermarks are intercepted at the gateway by a watermark detector implemented either with software or hardware.

Key words: electronic files, leaking, digital watermarking
