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.

wouldn’t that make it worse? basically any signal can bounce off you, making yourself even easier to track.

edit: wording

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.

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!

Yeah, wouldn't want to have to change hats, when I go to the swinger club after church.
