A hat that prevents facial recognition
kickstarter.comAren't these all pretty dependent on the systems you're trying to fool? Even with adversarial learning (https://en.wikipedia.org/wiki/Adversarial_machine_learning), if the system you're trying to hide from is different enough from the one you trained against, won't this not work well?
Although it does go back to the original, non-software meaning if the manufacturers create a _patch_ to update the hat.
They do address that at the bottom of the kickstarter page: "This means the hats we make today may not work in the future."
Wouldn't work today, either.
+1 for effort. I suspect that in the future we'll all have to don our Guy Fawkes masks before we head out into the half-deserted streets....
Or perhaps IR reflective face paint with a hat containing infrared LEDs in the brim. Everyone sees your face except CCDs.
If the hat obscures the eyes it doesn’t really need a fancy pattern.
The thing is, you don't necessarily want it to be obvious to people that you're hiding from facial recognition.
