The Sapienza computer scientists say Wi-Fi signals offer superior surveillance potential compared to cameras because they’re not affected by light conditions, can penetrate walls and other obstacles, and they’re more privacy-preserving than visual images.
[…] The Rome-based researchers who proposed WhoFi claim their technique makes accurate matches on the public NTU-Fi dataset up to 95.5 percent of the time when the deep neural network uses the transformer encoding architecture.

I was having a nice day :(
Yes, according to your wifi fingerprint, you had.

Why would someone research something like this? God damn, like use your life for good, homie
Well I heard about this and thought “this will be great for home automation”, but I also know that someone was equally excited about using this to rob people of basic freedoms or being a fucking creep or both.
If it’s your home why can’t you just have a camera or motion sensor. Rather than trying to adapt something that isn’t designed for the purpose.
Cameras require light, while radio waves works almost as well in darkness.
A motion sensor is an extra device that needs to be connected, have power and so on.
There are already radio wave motion- and room occupancy sensors where you can specify zones and so on, but if I could have personalized on top of that I’d take it.
Finally, using a thing for something useful other than its intended purpose is kinda fun.
You think if people who publish their work publicly didn’t research things like this, they would just never be discovered?
At least this way, we all know about the possibility, and further research can be done to see what can mitigate it.
I can imagine this being initially an accidental discovery like oh every time so and so’s body interacts with the WiFi signal it’s the same pattern… until someone starts exploring this further… and then some engineer or their manager started looking for applications for this. In my experience engineering researchers especially are very good with coming up with use cases for whatever tech they’re working with, with little ethical consideration.
I doubt it. You’d need to be looking really closely at the waveforms to notice this, so they were likely already doing something similar, like that research that can pinpoint where people are in a house based on their WiFi. They were probably already doing something creepy before they noticed that this was more straightforward than they expected.
Once you start playing with radiowaves and antenna you start noticing the intricate ways it plays with and around bags of water like bodies. I’m sure the original research on location/movement tracking was due to scientists trying not to get interference, later once they figured it out it was natural to see how much data they could get out of a radio interference profile.
I remember the original tech was going to be marketed as a way to tell if your old person (parent etc) had fallen down and stopped moving. Not the best use case, and then the privacy implications became clear. Once that happens the race begins to exploit the tech.
…But the eventuality here is something like a Star Trek tricorder that can take multiple vitals and detect irregularities from across the waiting room. Sensors that remember who was in a room and what settings they had. Etc. Some cool thing besides the bad stuff (microtarget those ads).
Everything is incremental progress in some way.
I remember years back someone doing experiments with Wi-Fi to see if a room was occupied based on signal attenuation.
This just looks like an extension of that.
Not everything is a giant leap
I’ve seen some article recently that the patterns of Wi-Fi/Bluetooth (don’t remember which one) interference with brainwaves can be scanned to reconstruct brainwave signature remotely, meaning that it might be possible to scan anyone’s EEG from Wi-Fi/Bluetooth distance. And there are some AI advancements for reconstructing inner monologue from EEG. So maybe we’re not so far from actual remote mind-reading.
Time for tin foil hats
You had non work related thoughts on three separate occasions last week. Please report to HR for attitude adjustment.
A truly horrifying prospect.
Tuesday, in 2025.
No. It’s Friday.
🏆 Here is an award for the best comment in the thread.
This may be the largest gap between the quality of an actors performance vs the movie it’s in.
Truly an abysmal movie, but Rahul Julia is so much fun to watch in it.
I’m impressed there’s a gif for this 🤣
No! This is Patrick!
they’re more privacy-preserving than visual images.
hhhhwat. How can they identify you and also be privacy preserving? 🤔
They know you are a person and they can call your a certain UUID, but there will be a hard time matching you to your name etc.
Camera’s can do face recognition (if your face is even in the database) to know who you are.
This only works until the point where they have your form in a database which they can check…
We have heard this non-sense before, only to find it’s trivially easy to connect to your PID.
Well, the alternative would be a camera in every toilet stall. See how our benevolent corporate overlords only have our best interest in mind?
They can see you’re a person but not exactly who you are.
How is that a “fingerprint”?
Well they can identify you are the same person but not your identity… So it’s like a disenbodied fingerprint.
I suppose they could potentially make some database and train an AI on it someday to match to actual identities, but usefulness would be pretty limited at only 95% accuracy. That’s a false reading 1/20 times, so I suspect it would fail bigly to accurately recognize people from large data sets.
That’s a false reading 1/20 times
And when has something like that ever stopped anyone?
It’s all AI. You should not worry about it. In fact you should not think about it. All is going to be fine.
And this here folks is the true ending. No one there is going to stop it as always.
Congratulations! You are now fully fucked!
There is the draft dodger, he is located in building #52556 in this city, info updated 125 milliseconds ago. He left his phone at his house 5 states away, go get him.
Someone’s going to use this to drop missiles on “baddies” with their sleeping families in 3 2 1
Reporting about starving children? That will be capital punishment for the whole family.
Reminds me of the Christian Bale batman movie where he could spy on everywhere from the bat cave. Seemed so far fetched it almost ruined the movie
No-one suspected Bruce Wayne’s “free WiFi for Gotham City” initiative
It was very much not even far fetched at that point. 1984 wrote about the same kind of surveillance, and at that time it would have been pretty far fetched. It was published in 1949; the video camera was only 24 years old at that point.
You know, this, and the using wifi to see through walls stuff to me just immediately seemed to fall into “don’t research this, it can only be used for evil”.
I don’t get why we bother studying these types of things.
We study it because EVERYTHING can be used for good or evil.
If we’d stopped researching anything that could be used for evil we’d never have gotten into the stone age
Yeah, like, why learn how to split the atom if all we can do is splode stuff. It’s not like we can cure cancer or power things without emitting planet killing gasses or anything.
This has me wondering how my sack of potatoes body would look 🤣
you can also take a picture of a person with a camera that senses light beams
The most primitive of physics concepts, the transmission/absorption/reflection of energy, is completely unknown to most people it would seem.
95.5% accuracy is abysmal for any use case these people want to use it for
what if you combine it with other types of imaging
Dingdingding
Wait… so the guys with tinfoil hats were on to something?
Except that the tinfoil hats don’t work
Maybe wearing a different tinfoil hat every day would mess up a person’s “fingerprint”
you might be onto something.
take a mylar square and place it somewhere random on your body every day.
Eat a piece of spinach and increase the iron in your body.
This is all beyond stupid and hysterical.
instructions unclear, I have glued spinach to my skin and the rabbits won’t stop chasing me.
need further instruction.
Actually you’ve gone far enough to baffle the system.
I would say have fun frolicking with the rabbits?
Yep it has to be random to mess with the algorithm. You could have fun and cut different shapes each day.
This shits already used by xfinity
Well, that’s quite different, it didn’t identify anyone
Neat. Good luck protecting yourself from this.
On the other hand, I’m seriously considering opening an Etsy shop selling foil-lined clothes. I’m pretty good at sewing. What do you think?
Then I’ll look for the person with the fingerprint of foil-lined clothes
Not if everyone buys it, because then we’d all look the same
You’d need fabric with continuous metallic threads that form a complete mesh to actually block the 2.4/5GHz signals - most DIY foil approaches leave gaps that WiFi can still penetrate thru.
I feel like you’re overthinking this. These are people who buy crystal-infused drinking cups to reset their personal feng shui. (Spoiler: it’s just glitter.)
I really wish I didn’t have morals. It’s so easy to make money if you’re willing to fleece people.
Or sell a “WiFi mask” to modify the signal to look like celebrities.
It’s so true. Would you like to buy some Trump memorabilia? Made in 100% American spirit in China
