基于WFP系统的网络反黄系统过滤驱动研究

随着互联网的普及,网络色情信息充斥了整个网络,严重败坏了社会风气,尤其对未成年人心理健康危害极大.本文分析了Windows Vista平台下网络反黄系统开发原理和关键技术,并对Vista平台下一种新的网络过滤系统WFP进行了剖析,研究并设计了基于WFP系统和正则表达式的网络淫秽信息实时过滤驱动,提出了一种新的过滤技术,该技术采用正则表达式和独特的二级表结构,实践表明该系统设计具有良好的实用性.

Study of Filter Driver of Anti-pornography System Base on WFP

With the popularity of the Internet,Internet pornography is flooding the entire network,which degrades social conduct,and especially has done great harm to the mental health of minors.The paper analyzes the principle and key technology of network anti-pornography system inside Windows Vista operating system.After discussing a new network filter system-WFP,the paper designs and implements a network anti-pornography real-time filter driver based on WFP and Regular Expression inside Windows Vista operating system.We put forward a kind of new filter technique which adopts a special second-class form structure.Practice shows that the system is a good practical design.
