Face recognition has another problem - or two.
When I was a graduate student in the 1980s, my university department had a display of full-face photographs of its staff members, down to and including the cat which frequently visited the place. This means that anyone who wanted to spoof a face-recognition program (which were of course unknown at the time) could simply take a picture of the photo display and extract any desired picture for use in a fake ID.
Also, there was another staff member - I shall call him Richard S - whose photo was very similar to mine (start with a beard and glasses). Just right to confuse a face-recognition system. In real life no-one could possibly confuse us, as I was 20 years younger and more than a foot (30+ cm) taller than him.
