Visual behavior early warning prompting method and system for automatic teller machine (ATM) bank card

The invention discloses a visual behavior early warning prompting method and a visual behavior early warning prompting system for an automatic teller machine (ATM) bank card. The method comprises the following steps of: 1, periodically acquiring face information about a user using an ATM and people around the user; 2, establishing an ATM user behavior state automaton, and judging a current behavior state of the user; 3, comparing the face information acquired by the step 1 according to acquisition time; and 4, performing comprehensive analysis by combining information returned by the steps 2 and 3, making a judgment on normal behaviors and abnormal behaviors, and if the abnormal behaviors are judged, performing early warning prompting. In the method and the system, the influence of user behaviors on the safety of the ATM is focused, potential hazards are adaptively identified from the stages and changes of the behaviors by analyzing the behaviors of the ATM user, and the user is warned, so the hazards are prevented, the potential safety hazards of the ATM caused by the user behaviors are avoided, and the method for the safety of the ATM is more active, low in cost and efficient.
