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.
Cool
If it doesn’t get used for bad purposes it is very cool yes. So no it’s not cool at all. It’s fucked.
People willingly provide enough tracking of themselves already
While this could have military applications, the need to generate a profile of the person you want to track makes this less of a concern for your average “carries a phone everywhere” person
