In the past, people discovered that if they applied face paint in a specific way, cameras could no longer recognizing their face as a face. Now with this information, you get (eg. 4?) different people. You take a clean picture of each of their heads from a close proximity.
Then, you apply makeup to each of them, using the same method that messes with facial recognition software. Next, take a picture of each of their heads from a little further away.
Fill a captcha with pictures of the faces with the makeup. Give the end user a clean-faced picture, and then ask them to match it to the correct image of the same person’s face but with the special makeup.
Mess around with the colours and shadow intensity of the images to make everyone’s picture match more closely with everyone else’s picture if you want to add some extra chaos to it. This last bit will keep everyone out if you go too far with it.
Face recognition ability in humans varies wildly, unfortunately. And that’s without making it harder with face paint. Regular people can get completely fooled by simple things like glasses on/off or a different hairstyle (turns out Clark Kent was on to something after all).
This is a bit out there, so bear with me.
