1. A fraudulent act recognition device configured to be operatively coupled to a camera that monitors operation of a settlement terminal by a purchaser, the fraudulent act recognition device comprising a controller configured to:

review imaging data provided by the camera to recognize an action of the purchaser who performs the commodity registration operation based on a position of a component of the settlement terminal and a position of a hand of the purchaser while the purchaser faces the settlement terminal;
determine that a movement of the hand of the purchaser holding a commodity for which the commodity registration operation is recognized is a movement associated with replacing the commodity in response to a determination, based on the imaging data, that the movement of the hand includes at least one of (a) movement of the hand toward a floor or (b) movement of the hand toward an area behind the purchaser;
determine that the action of the purchaser is indicative of the fraudulent act in response to a determination that the movement of the hand of the purchaser is the movement associated with replacing the commodity; and
