In Ken MacLeod's novel "The Execution Game", which featured some amateur espionage and OPSEC tactics as plot elements, there was a specific marque of makeup that was known to throw off the facial recognition algorithms in play. I have no idea if such a thing actually exists or not, but if so, it's probably a lot less "Look at me hiding from The Man" than walking around as Guy Fawkes all day.
