一种基于微过滤驱动的电子文档保护系统

摘要

针对当前内网中涉密文档可能出现泄露等安全性问题，提出了一个基于微过滤驱动的电子文档保护系统模型。将文档涉密标识、访问控制策略和密钥作为标识信息嵌入文档头部，唯一的标识文档；并在此基础上采用 Minifilter 驱动技术实现文档的访问控制和透明加解密。实验结果表明，该系统能根据访问控制策略保护涉密文档，有效地防止了内网中涉密文档的泄漏。%In view of the current network security issues ,such as possible leak classified documents ,a electronic docu-ment protection system model is proposed based on minifilter drivers .Document classified identification access control policy and the key as the identity information are embedded in the document head ,only the identity of the document .Additionally , minifilter driver technology is used for access control and transparent encryption of the document .The experimental results show that the system can protect classified documents according to the access control policy ,effectively prevent the leakage of classified documents in the Intranet .
