I'm generally pro research, but occasionally I come across a body of research and wish I could just shut down what they're doing and rewind the clock to before that started.
There is no benefit of this for the common person. There is no end user need or product for being able to identify individuals based on their interactions with WiFi signals. The only people that benefit from this are large corporations and governments and that's from them turning it on you.
Continued research will ease widespread surveillance and mass tracking. That's not a good thing.
Could be developed into a useful tool for search and rescue

Ironically, they're still wrong, because even in their wildest conspiracies, they didn't imagine Wi-Fi could be used to "take pictures" of a sort.
Tinfoil hat conspiracy theorists predate wifi by at least a decade

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

Probably not.
This kind of thing relies on the fact that the emitter and environments are static, impacting the propagation of the signals in a predictable way and that each person, having a unique physique, consistently interferes with that propagation in the same way. It's a tool that reports "the interference in this room looks like the same interference observed in these past cases."
Search and rescue is a very dynamic environment, with no opportunity to establish a local baseline, and with a high likelihood that the physiological signal you are looking for has been altered (such as by broken or severed limbs).
There are some other WiFi sniffing technologies that might be more useful for S&R such as movement detection, but I'm not sure if that will work as well when the broadcaster is outside the environment (as the more rubble between the emitter and the target the weaker your signal from reflections against the rubble).
Don't think of this as being able to see through walls like with a futuristic camera, think of this as AI assisted anomaly detection in signal processing (which is exactly what the researchers are doing).

It is cool for home automation if you can turn it into a presence detection software (do not connect your Homeassistant to the internet though)
If all you need is presence detection then a motion sensor would be vastly more efficient.
If you actually need identity detection, then maybe, but you'll still have to have a camera or detailed access logs to associate the interference signature with a known entity and at that point you may as well just put an RFID reader under the bowl you throw your keys into or use facial or gait detection.

That's a very unique fingerprint he's got.

You had non work related thoughts on three separate occasions last week. Please report to HR for attitude adjustment.

Let me know when I can selfhost LibreFi Security on my router and use it for myself. Sounds great for private home use.

Sorry dude I forgot to add your bio signature to my WiFi router.

I can imagine this being initially an accidental discovery like oh every time so and so’s body interacts with the WiFi signal it’s the same pattern… until someone starts exploring this further… and then some engineer or their manager started looking for applications for this. In my experience engineering researchers especially are very good with coming up with use cases for whatever tech they’re working with, with little ethical consideration.

When anyone or anything says that their product works "up to x%" I always presume it doesn't really work at all.
Christ, 1% is included in that "up to 95.5%" vague bullshit statement.I believe the reason they had to say "up to" is because the "signatute" will vary day to day ever so slightly (natural weight fluctuation), and if you gain or lose weight it can change dramatically, so the AI would have to constantly consider that and adjust it's records.
Honestly, unpopular opinion, but as long as it isn't very short wavelength RF and they allow for self-hosted/open-source alternatives, I do find it a bit more privacy respecting than cameras, of course they have to say they are using the technology in public places.
It also has it's ways of fooling it, instead of wearing a wig and a false nose, you could wear a carbon-infused silicone fat suit to change the way you interact with RF.

Stilsuits: get it for the unbearable heat as we turn the Earth into a desert, now with wifi blocking!

Being able to scan and model a 3D environment using wifi? Sure. Wifi-fingerprinting the people in the scan? Why?

Yes, according to your wifi fingerprint, you had.

Why do you need to identify specific cats over merely the presence of movement or cats in general?

Because I want to know which cat is getting up to shit they shouldn't

Well I heard about this and thought "this will be great for home automation", but I also know that someone was equally excited about using this to rob people of basic freedoms or being a fucking creep or both.
