How to avoid facial recognition in Hong Kong?

There's CV Dazzle [1], but any kind of system would have to be used by several people in a location to be more effective, preferably with people switching things up often.

Juggalo or Juggalette face paints could also confuse current recognition systems.

Sadly the projector in the link is just an art project/proof of concept. So maybe something like that, but for real?

Otherwise, glasses, scarves, hoodies, umbrellas, numbers... the usual, no? Makeup and lofi prosthetics if you wanted to get fancy.

In any case isn't facial recognition rather less an immediate issue than, well, tear gas?

Wearing a mask. I know they banned it, but it’s not like they won’t come after you because you didn’t wear a mask. I mean, that’s exactly the point of the facial recognition. Instead of disappearing today, you’ll disappear tomorrow.

If you’re not into the “liberty or death” thing, you might want to flee China instead.

Either way, good luck.
