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.

Why would someone research something like this? God damn, like use your life for good, homie

Everything is incremental progress in some way.

I remember years back someone doing experiments with Wi-Fi to see if a room was occupied based on signal attenuation.

This just looks like an extension of that.

Not everything is a giant leap
