Scientists Use WiFi to See Through People's Walls
Scientists Use WiFi to See Through People's Walls
This won’t get creepy.
“We developed a deep neural network that maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions. The results of the study reveal that our model can estimate the dense pose of multiple subjects, with comparable performance to image-based approaches, by utilizing WiFi signals as the only input.”
"we threw a deep neural network at the wall to see if it sticks"
Time to plaster your outer walls with fine wire mesh.
Umm, article from Jan 19, 2023. I remember seeing it then. Is there anything new on this?
The paper: [Submitted on 31 Dec 2022] - I'm not sure if it's out of prepublication yet.

I am going to repeat myself forever it seems. We got it wrong when we decided that you only have privacy when someone can't physically see what you are up to. Nothing else is treated this way. You are not allowed to drive as fast as your car can physically move. You are not allowed to go into anything locked as long as you are able to pick it. You are not allowed to steal whatever you want as long as no one tackles you for it. And yet somehow some way it became understood that merely because someone can get a photo of you they have the legal right to do so.
As if access to better technology means you should follow less moral rules vs the opposite. Someone with a junk camera of the 80s can do far less perving compared to the new cameras+drones out there.
Henceforth, the building code shall make mandatory that every room be perfectly grounded Faraday cages (/s).
Still, imagine lethal drones integrated with that technology (of course, they already have infrared, maybe even some adequate wavelength of X-rays).
Nevertheless, pretty cool to see how far we can take preexisting technology with the help of some deep learning layers.
Doesn't this mean the matrix film was right with their visualization (regardless of orientation)?
Years ago there was a journal on gait recognition through home WiFi.
No one else getting batman : the dark knight vibes ?
Y’all, just because you can, doesn’t mean you should.
scientists bout to see me on the goddamned pot.
The reason this is good for privacy is because we don't need a new smart device to send other (like video) data away for heavy processing in the cloud.
We might instead be able to just update wifi routers to create local functionality.
Then it will depend on the router and the user configuration what actually happens with that data.
The user can have full local control…. Except neighbours wifi could be spying and so could someone with a wifi device in a car. But if putting a faraday cage around peoples exterior walls (combined with an underground physical cable to an internal extender for phone and roaming while insid) becomes a thing then it looks it could be a great system theoretically.
Gotta wait to see how it might look in practice though.
I now have no sense of privacy anymore
old ooold tech. has been possible since at least 2013
Damn, hackers do be eating good in the future 👀
This is Batman's technology.
