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.

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!

[–] Diplomjodler3@lemmy.world 7 points 1 day ago

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

Many different items of tinfoil clothing. Tinfoil shirt today, tinfoil codpiece for the weekend

Have you tried turning off the router?

[–] kerntucky@infosec.pub 9 points 1 day ago

Yeah, but then I had no excuse to wear a tinfoil codpiece.
