A method (100) is proposed for recognizing attempts at manipulating a self-service terminal, specifically a cash dispenser, in which a control panel with elements arranged therein, such as a keypad, cash-dispensing slot, etc. is provided, wherein a camera is directed onto at least one of the elements and wherein the image data generated by the camera are evaluated. Using edge detection, at least one edge image is created from the image data generated (step sequence 120). The edge image is evaluated using a reference edge image (step sequence 130). To generate the reference edge image, several individual images are used (step sequence 110). Fully automated evaluation and recognition of manipulation attempts is possible using edge detection. |
