We used to recommend people to run the newest stuff possible, but we came to a point that maybe it's better for us to keep with older tech for a good while
Or go to more civilized countries for vacation to get not backdoored hardware.
From what I've just read, the tech doesn't seem ready to identify people yet. It can supposedly detect hand gestures, but facial recognition I seriously doubt. But that's probably just a matter of improving the tech. See this article for more info.
From OPs linked article...
I can totally believe when it tracks a person it can tell when the same person walks by again later. But matching people with their actual identities would require a database of wifi scan data that simply doesn't exist yet.
that's a trivial problem to solve. combine this with a camera for facial recognition in a public space. then you've got wifi signature combined with the photo/video for facial recognition. then presumably you can use the WiFi signature anywhere else, even without the camera and be able to identify people.
I was wondering about that. The article didn't say anything about being able to identify the same person walking past a different router. And I can't imagine the study didn't try. So I assume it doesn't work.
That's connection history. CSI motion detection software storing information it collects would be entirely independent of that. How much it saves and for how long would depend on the size of the router's memory.
