Abstract
Methods, systems and apparatus for securing user input to a terminal such as a self-service terminal. The temperature of one or more keys pressed by a user when entering user information into a terminal (e.g., user PIN) is determined. The change in temperature on the keys' surface from the user touching the keys reflects a heat signature that can be identified by thermal imaging devices. A desired temperature for the keys that will mask the heat signature is determined. The temperature of the keys is adjusted (e.g., raised or lowered) to the desired temperature.
