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

Strange. Shitting on your bosses desk is still free. Hmm. Interesting loophole.

You get poo time? That's socialism!

Please drink a verification laxative?

Since it 'figerprints' you, changing your fingerprint by blocking parts of the signal with pieces of foil doesn't seem like a terrible idea.

Now, the question is: is such a tactic like wearing gloves, or like using super glue?

The tracking happens even with a big reflector/scatterer on your head, but as long as you dont wear it regularly, the system would have difficulty identifying you from wave propagation alone

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.

I hate it when commercials say "up to 100%." It's literally a pointless metric; that could mean anything from 0% to 100%, inclusive.

edit: Closed quote.

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.

I wish this was the goal, instead of large corpos doing large corpos things

Put an airtag on the collar. Done.

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

You are correct because something similar has already been used

Microwaves are the same as wifi waves, these are able to detect bodies and whether the bodies are beating or not

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).

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

How is that a "fingerprint"?

This is fine.

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