Ordinary WiFi could become a powerful new form of invisible surveillance. Using standard wireless signals and artificial intelligence - researchers demonstrated a system capable of identifying people. (www.sciencedaily.com)

jesus, 100% accuracy over 197 people? basically the only way to be a private person then would be to live in the woods with no internet

i assume it works similar to an airport scanner if it isnt gait analysis, it measures your actual body. excited to have the anti-trans wifi alarm go off when you try to enter the correct bathroom. also incredibly hard to do crime, maybe there is some sort of way to obfuscate your body to make it look like you have large hips (drag gear!) but wont be detected as clothing

Maybe glueing aluminium foil to the clothing to spice up reflections can help.

The end stage of leftist conspiracy theories vs libertarian ones again rears its head:

"You're wearing tinfoil because you believe mole people are trying to microwave your semen with 5g. I'm wearing tinfoil because a public study released showing wifi can be used like sonar and it's literally not even a secret they just published the papers you can read it on a normal website. We're not the same."

In 2020 my mom lived in a place where most people didn't mask, she said "If anyone gives me shit I'll say I'm doing it to block the government facial scanning technology." It's interesting that it's a legitimate reason to wear a mask all the time these days.

Even better if you print a face on the mask.

probably dont even need it on the outside just do it around your torso under clothes or something, could probably sew it into a mask as well. theres likely a way to do this comfortably, sew it into a second shirt or something

just live in the woods with only wired internet. Cat6Gang stay winning.

Even if you don't have WiFi, this could easily be paired with a transmitter (WiFi router/AP). You'd need to make your dwelling into a faraday cage.

At some point we just need to say "that's cool and all but you're not allowed to work on this anymore"

[-] DasRav@hexbear.net 26 points 2 months ago

So many ethical and good uses of AI being discovered. It's really such a mystery why many people hate it.

[-] Hohsia@hexbear.net 11 points 2 months ago

It’s that old pesky human condition (TM) you see!

[-] KnilAdlez@hexbear.net 25 points 2 months ago

Yeah, I've seen very similar tech advertised as a feature (detecting room occupancy) on routers.

[-] EndlessNightmare@reddthat.com 11 points 2 months ago

Some ISPs offer it as a service. I think they market it as part of their home security packages.

[-] Maeve@kbin.earth 24 points 2 months ago

I'd bet the police apparatchik it's been happening for a decade.

[-] MolotovHalfEmpty@hexbear.net 18 points 2 months ago

It definitely has. The retail industry has been using a version of it for at least four years that I know of.

[-] 7bicycles@hexbear.net 9 points 2 months ago

You'd probably be correct, the basic premise has been around since 2013

[-] Poutine@hexbear.net 3 points 2 months ago

Was the premise not shown in 2008 film The Dark Knight ?

Me and the boys at the LAN party with no interruptions

Kilowatt RTX 5090s would make the smell so much worse in a modern re-enactment.

[-] Fossifoo@hexbear.net 3 points 2 months ago

The power requirements would be through the roof. Wonder how well Dreamhack does. 10k PSUs at a kW is 10MW. 😬

[-] peeonyou@hexbear.net 1 points 2 months ago

some of these guys are better than the others

[-] Awoo@hexbear.net 15 points 2 months ago

Man. I can think of so many good ways to use this but it's only going to be used for evil.

[-] himeneko@hexbear.net 14 points 2 months ago

i knew a guy at work that worked on this but with ultrasound coming out of a cheap speaker. it scared me.

[-] Hohsia@hexbear.net 14 points 2 months ago

Seriously when is anarchy ushered in because I’m tired of this shit

[-] hotspur@hexbear.net 11 points 2 months ago

There a couple open source repositories out there for setting something like this up, or at least the basic sensing. I started looking at it a bit but then got bored and didn’t try it out. You can set it up on a computer in your home (was gonna use a spare desktop I run Linux on), and the package had the ability to start to correlate movement skeletons as unique based on repeated motions. It freaked me out that it was theoretically possible to invasively spy on my neighbors on either side just by downloading some open source software… anyway I never went through trying to get it installed or working and it probably would have been a finicky setup, but the potentials for crazy surveillance are pretty huge with the wifi sensing, and outside of living in faraday cages not sure how much you could prevent it.

Diy Faraday cage youtube celebs were right

[-] hotspur@hexbear.net 11 points 2 months ago

Say 5 years ago I would have said: that’s nuts. But more and more these days I’m thinking, yeah having a house with some signal blocking might not be such a bad idea… not really feasible for most people, but you could integrate somewhat in new construction, and certainly you coild foil a room and use EM paint… but would be pretty weird.

Case anyone’s interested, couple of resources on SCIF wall construction:

With the information it constructs and AI technology you could feed a photo of the neighbour into the AI and have it turn that information into real 3d environment with a real 3d model of the neighbour that actually looks like them.
