This is a bit out there, so bear with me.
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.
I have also encountered some different styles over the years.
A good one that I saw involved three shapes. You had a triangle, a sphere, and a cube. There were three patterns. Striped, polka-dotted, and plain. The shapes also had textures. Some shapes were smooth, others had fur. There were 3 backgrounds. I think one was brick, one was flowy colours, but I forget what the third background was.
Anyways, out of those options, you were generated a random combination of two shapes, 2 colours, a texture, and one background. The captcha generated it's own 3 randomized images, but the fourth image matched your generated image. The placement of the fourth image was also randomized.
I have to be honest, I was tipsy when I used it and it kept me out for longer than I'd like to admit haha.
This would just generate data to train AIs on.
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).
Sounds elaborate... For humans to solve
Do you have any suggestions that would be immune to having the same flaw?
