A security code input may be obfuscated from a thermal imaging device by randomly heating a random set of inputs of an input device. The security code is inputted on an input device, which communicates with a security system to grant or deny access to a user based on an entry of the security code. The input device includes a plurality of hearing elements. The input device may receive an input from the user. A random set of heating elements including one or more heating elements, are generated from the plurality of heating elements. A temperature is determined for the one or more heating elements of the random set of heating elements. The temperature is then applied to the one or more heating elements of the random set of heating elements of the input device.
