METHOD FOR SECURITY CERTIFICATION BY USING WEB CAMERA

摘要

PURPOSE: A security certification method using a web camera is provided to prevent hacking by authenticating virtual buttons which indicate a unit section within a frame through a web camera. CONSTITUTION: A web camera is driven, and a unit region within a frame is displayed. The variation of the unit regions is sensed. An outline of the sensed unit regions and a variable color are extracted and normalized. When the unit region is recognized after confirming a recognized region, a unit regional value is transmitted. Unless the unit region is recognized, the variation of the unit regions is sensed again.
