I am work just thinking random stuff. and a few thoughts collided. with every wearing masks now.
So China says thy have Facial recognition with mask on, in a defcon talk I saw on YouTube a while back talked about obfuscation of the recognition with clothing, bumper stickers, etc. That had me thinking could one make masks that confuse the recognition software, and how would one test that out?
we all could walk around wearing strange looking masks for the fun of it
Facial recognition is great if you have a small subset of complete faces When you have a medium/large subset of faces, it’s bad. It’s borderline unusable if they’re wearing masks. Just not enough points to differentiate against.
I’ve had a theory about how you can do this with light a while back. I’m tempted to test it every now and then.
I’d just put a lot of very powerful IR SMD LEDs just behind the superficial part of the mask to blind every camera. It could easly run off of a powerbank with wires running behind one hear and going down to a pocket.
Not the easiest solution but it won’t be easy to spot with a glance.
Just cover a hoodie in adversarial images and enjoy. Can’t get classified if it can’t tell you’re a person.
That being said, this doesn’t work for the more structured facial recognition services in the US. The most common one you’ll encounter is when entering US Customs. The ‘fast track’ aisle that has you lean in and take a picture? That’s adding you to CPB’s database. You don’t get to go through those gates until your face passes, so adversarial images won’t work.
Maybe Choina is just lying about face detect through mask (as if even they could tell the difference between their faces)
Really they just track the metropass used moments before, or the cellphone they are carrying…
I think some places are too dense for fursonal personal transit. (I don’t know what transit furry people use. Heim! I mean Phase! I don’t even remember)
I do not envy the people having to live / visit such places.
If I manage to find a pattern that I like will not come up as something dangerous like an assalut rifle or a bomb I might print myself a couple hoodies like that just for fun.
I don’t trust anything coming out of China.
at the rate the recognition systems get better and better, and one day it will be like the Minority Report reading your retinas as your go about your business.
I am all for feeding the system as much junk as i can
