摘　　要：随着数字图书馆的快速发展,计算机文件系统的安全性越来越受到重视。文章讨论了基于文件系统过滤的数字图书馆文件透明加密系统的实现原理,过滤驱动的设计与实现,文件读写中加密与解密的实现等关键技术,对比了透明加密技术与传统加密技术,为数字图书馆中的文件系统安全工作提供借鉴和参考。With the rapid development of digital library, more and more attention has been paid to the security of file system. This article makes a discussion on the theory of transparent encryption and decryption file system based on file system filter driver. Some key technology such as, the design and realization of filter driver, transparent encryption and decryption in the reading and writing of files is discussed. The superiority between the technology of transparent encryption and decryption and the technology of conventional encryption and decryption has also been compared. The design has the important reference value in the security field of file system in digital libraries.
