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'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.

A truly horrifying prospect.

You had non work related thoughts on three separate occasions last week. Please report to HR for attitude adjustment.

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.

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?

Stilsuits: get it for the unbearable heat as we turn the Earth into a desert, now with wifi blocking!

Let me know when I can selfhost LibreFi Security on my router and use it for myself. Sounds great for private home use.

ALERT ALERT ALERT

Sorry dude I forgot to add your bio signature to my WiFi router.

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