摘　　要：分析了信息过滤系统的实现方案及关键技术,设计并实现了一种基于内容和地址的不良信息过滤系统.文中主要介绍了系统的构架、规则库匹配过滤算法、管理机与被监控机的通信技术,并给出了通信数据包的数据结构.系统运行在Windows98或Windows 2000/XP平台上,经过实际运行测试,证明系统性能稳定、规则库中的敏感信息能有效过滤,达到了预期设计目标.This paper discusses how to design and implement this filtering system, a general model of content and url based security filtering is put forward . It discusses the theory and implementation methods , including the system architecture, the communicate technology between management machine and monitor terminal, the data structure of the communicate packet. This system runs on Windows 98 or Windows 2000/XP operating system, it shows that system performance is stable, the sensitive information can be filtered effectively according to rule-database, and achieves the anticipated design.
