This is also how we stop our biggest abusers of our service. They leave such a unique fingerprint from all our other customers, we just quietly shadowban them.
It doesn’t need to be as dramatic as this. The goal is simply to obscure key parts of the face that are commonly used for individualization. Between the eyebrows, the bridge of the nose, jawline, eye tilt, etc are all common key data points that facial recognition systems use to differentiate between similar faces. You can also try to avoid facial detection from pinging you in the first place, by obscuring the expected oval head shape. Style your hair asymmetrically, have bangs that droop over one eye, break up the expected round shape, use a color that mismatches your skintone, etc…
Your face paint is definitely an extreme example of the latter. But the important part is that some may actually still be able to detect a face (even if it can’t positively identify them) because they didn’t do anything to obscure the head shape or obscure at least one of their eyes.
I suppose putting on a very unique pair of glasses would for sure avoid facial recognition. Why would there be a need to recognize your face if u make yourself so obviously different vs others. Haha.
A dumbass camera would be sufficient. No need for complicated facial recognition camera.
You take the image recognization machine, and you run the output of your own algorithm through it, training your algorithm to value patterns that confuse the first machine.
I wouldn't trust this to work against updated machine learning algorithms.
