An example described herein may involve receiving a temperature measurement associated with an input component, wherein the temperature measurement is received from a temperature sensor, and wherein the temperature measurement indicates a temperature of an input element of the input component; determining that the temperature of the input element satisfies a threshold temperature; and causing an infrared element to emit infrared light in association with a position of the input component. While the infrared element is emitting the infrared light, capture information associated with a user interacting with the input component may be obfuscated.
