There would still be a temperature difference for some time after entering a PIN until the keys used are fully cooled. So this method might not fully mitigate the attack.
A better solution could be to heat the keys to about the same temperature as a human's finger tips, so that no heat is being transferred while entering a PIN.

- Arrath 4y agoI'm curious what kind of software solution there could be to this? Some from of pattern matcher in the camera obscuring the video output when it determines its observing a number pad?
- jaclaz 4y agoMaybe something loosely similar to the protection that is said to be present in very high level colour photocopier that prevents from photocopying money?
