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
Die shrinks effect long term durability. We passed that point around 10-14nm
Or go to more civilized countries for vacation to get not backdoored hardware.
Do you think every country has its own router hardware manufacturer and commodity chip manufacturer? 😂
The 2 giants that make 95% of consumer routers around the world and the few companies that design the chips for them are both in heavy surveillance states.
does not matter if the factory software just uploads the info because you wouldn't know anyway
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 load bearing "yet"
Well in theory every tech possibility is a "yet", but the way I read this it seems like a person or object's interference pattern is particular to the local signal environment - not like a fingerprint a different system could recognize at the airport.
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.
