摘　　要：文件系统过滤驱动技术是解决文件安全性问题的一种有效的、可靠的、透明的技术实现手段。利用文件系统过滤驱动解决文件安全性问题时,需要标识各种文件,并要求文件标识对用户而言是透明的。文中基于Windows2K/XP/2003的文件系统过滤驱动,将文件标识嵌入到文件体内,既实现了对单个文件或多个分散文件的透明标识,又避免了丢失文件标识的可能性,且标识长度没有最大限制,保证文件安全防护系统的较高有效性和较强可靠性。File system filter driver technology is an effective, reliable and transparent technique to solve the problem of document security. Using file system filter driver to resolve the problem of document security would lead to marking various files, and for users, the file marking must be transparent. This paper describes that, based on file system filter driver in windows 2K/XP/2003, the marking of a single file and of multiple scattered files as well is achieved by embedding file marking in the document, while there is no restriction on the maximum length of the file marking, thus guaranteeing high efficiency and strong reliability of document security protection system.
