Abstract: The implementation plan of a Browser Helper Object(BHO) based website filtering system is proposed in this paper by using the technologies of web filtering,anti-destruction and keyboard monitoring.The details of the sensitive image detection mechanism embedded in the web filtering technology are introduced emphatically,where a flexible and strict filtering system and an online environment with reliability and security are available owing to the triple filtering method:URL filtering,text filtering and sensitive image filtering.The results of experiments verify the effectiveness of the proposed system.

Key words: website filtering, sensitive image detection, Browser Helper Object(BHO)
