Wifi can recognize and track individuals

[Dopious]

Up to 95 percent accuracy.

A group of researchers at La Sapienza University in Italy has shown that Wifi signals can be used to physically identify and track people with high accuracy.

In an article published in mid-July, the researchers review how they can produce "fingerprints" based on how Wifi signals are reflected and refracted by bodies, using machine learning and artificial neural networks.

Experiments have shown that these “fingerprints” are stable enough that people can be recognized even if they change clothes or are wearing a backpack. The accuracy is up to 95 percent (average recognition 88 percent), which according to the researchers is in line with other methods for automatically recognizing individuals in different contexts.

The researchers call their technology “WhoFi” and present it as a possible solution to the problem of re-identifying people who have been seen in one location via surveillance camera and then found again in the feeds from surveillance cameras in other locations.

So once you connect to a network it can track and identify you.

Do you need to connect to another network for it to find or follow you?

Maybe missed that bit

Not read it all yet. Summarize it and ask in AI.

Yeah I'll be honest I been srinking so I read what I could lol

I asked AI that, here is what it said:

Based on the paper you provided, the WhoFi technology does not rely on a person connecting to a Wi-Fi network.

The system works by using a Wi-Fi transmitter and a receiver to create a sensing area. It identifies a person by detecting how their physical presence—their body, bones, and organs—distorts the Wi-Fi radio waves as they move through the signal's path.1 This distortion creates a unique "radio biometric signature."2

Therefore, you do not need to be connected to the network for it to find or follow you.3 The system is sensing your physical body's interaction with the Wi-Fi signal itself, not the activity of a device you might be carrying.4

Wow.

Thanks for that.

Shocking.




Scary thing is this probably been around for ages and now we learning about it.

Which means "they" probably moves onto something else.

That's the conspiracy guy in me thinks.

Always new tech or info comes out it's because it's old to "government"

This is how phone apps track you and ban your accounts

It can get freaky how good tracking getting now.

Here is another one - turns out they've been surviellancing people by using their passport photos for years - https://bigbrotherwatch.org.uk/press-releases/passport-searches/

Don't know what they're problem is. Crime rate is at an all time high. Poverty is at an all time high. Illegal immigration is also at an all time high and apparently they're priorities are following ordinary people going to pick up bread and milk from the shop and snopping on kids playing roblox in their mums basement.

You won't get your money back if your gran gets scammed but you sure as hell will get a visit if you don't pay your TV license.

I know of people in Spain that were convicted with info the police got from the WiFi box, they were using the usual precautions for their line of “work” like encrypted apps and so forth for messaging/calls… but they didn’t count on connecting to their WiFi would screw them.

I wonder how these guy work around it. Mobile router perhaps?

Don’t connect to WiFi lol

Mind ur privacy ?
Be robin hood no one will find where u are.
There are times like this i think in going and live in the most isolated area that I can find
