<p>A method and a device (DET) are proposed to defend against electronic spying during the transmission of image data (Sb) or image signals (Sa) that are generated by a camera (CAM) installed at a self-service terminal (ATM), said camera recording an area (A0) that covers an operating area of the self-service terminal (ATM). As soon as events occurring at the self-service terminal (ATM) in the recording area (A0) or outside of said area, in particular actuation of a key pad (KBD) and/or insertion of a card into a card slot (SLT), are detected, the generation of the image signals (Sa) and/or the transmission of the image data (Sb) is controlled as a function thereof, for instance at least the sensitive areas or partial image data (Sb′) in the image data obtained (Sb) are blanked out or replaced by artificially generated data.</p> |
