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.

They know you are a person and they can call your a certain UUID, but there will be a hard time matching you to your name etc.

Camera's can do face recognition (if your face is even in the database) to know who you are.

This only works until the point where they have your form in a database which they can check...

We have heard this non-sense before, only to find it's trivially easy to connect to your PID.

Never said that it wasn’t easy, it’s just harder than with facial recognition. In theory you could do it correctly in a way that it isn’t indentifiable.

Also this works in places where faces are protected
