No. It's Friday.

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.
Chuck vindicated. What a chicanery.

So, you're saying the tin foil hat people were right all along?!

You know, not everything needs to be invented...

hhhhwat. How can they identify you and also be privacy preserving?
It's all AI. You should not worry about it. In fact you should not think about it. All is going to be fine.

No! This is Patrick!

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

I think you will be the one guy in the crowd wearing foil-lined clothes.

I'm generally pro research, but occasionally I come across a body of research and wish I could just shut down what they're doing and rewind the clock to before that started.
There is no benefit of this for the common person. There is no end user need or product for being able to identify individuals based on their interactions with WiFi signals. The only people that benefit from this are large corporations and governments and that's from them turning it on you.
Continued research will ease widespread surveillance and mass tracking. That's not a good thing.

Ironically, they're still wrong, because even in their wildest conspiracies, they didn't imagine Wi-Fi could be used to "take pictures" of a sort.

Not if everyone buys it, because then we'd all look the same

The tracking happens even with a big reflector/scatterer on your head, but as long as you dont wear it regularly, the system would have difficulty identifying you from wave propagation alone
So wear many different hats. Got it.

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. There 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.

Oh fuck all the way off.

Great, another dystopian way for authorities to observe me on the shitter

I mean, wouldn't you anyway? You don't wear your good Sunday tinfoil hat to work. That one's for church and swinger club visits only!

Or sell a "WiFi mask" to modify the signal to look like celebrities.

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.
