摘　　要：基于BHO劫持技术实现了一个轻量级的上网行为监控系统。该系统通过BHO实现与IE浏览器的绑定,确保了用户每个Web页面浏览行为都能得到有效监控。通过捕获DISPID_BEFORENAVIGATE2和DISPID_DOCUMENT-COMPLETE事件,并使用页面替换和脚本执行两种方式,实现了网站屏蔽和网页过滤功能,达到了对用户浏览不良或非法Web页面行为进行监控的目的。通过使用模块化设计思路和"捎带"的"心跳"信号报告策略,使得系统能够同时适用于个人用户和机构用户,并具有较高的通信效率,从而提供了一种具有较好通用性和有效性的网络防护手段。An Internet exploring behavior monitor is implemented based on BHO hacking technology to effectively monitor and control all operations of webpage exploring by binding the system with IE. Firstly, two events of DISPID_ BEFORENAVI- GATE2 and DISPID _ DOC are caught. Secondly, webpage replacing and script executing technologies are used. Based on these methods, functions of website blocking and webpage filtering are implemented to fulfill the target of monitoring and controlling the activities of a user to explore illegal or unhealthy webpage. Thirdly, modularity design idea and piggy- backing heartbeat reporting technology are used to elevate universality and improve efficiency of the system. Based on these methods, this system is used for both individual user and an organization to provide a lightweight network safeguard tool.
