[Theatlantic] Spying on humans using wi-fi signals might be possible

post #1 of 10
Thread Starter 
Quote:
As people move through a space with a wi-fi signal, their bodies affect it, absorbing some waves and reflecting others in various directions. By analyzing the exact ways that a wi-fi signal is altered when a human moves through it, researchers can “see” what someone writes with their finger in the air, identify a particular person by the way that they walk, and even read a person’s lips with startling accuracy—in some cases even if a router isn’t in the same room as the person performing the actions.

By conservative estimates science and governments are a 100 years in advance to what is available commercially.

On a related note, they are trying to use phemto photography to spy on people as well.

What is this obsession with spying on people?

wifi signals to spy...
cameras to spy....
satellites to spy...

The desire for power and control under the guise of safety. The insatiable attitudes of the ruling class remain largely unchanged.

I like this stuff. Voice can also be recorded quite ingeniously due to the "sound" emitted from LED lights when they blink rapidly to produce their light (the human eye sees it as a steady stream of light.)

https://youtu.be/hliHBeC1sco?t=4m54s

Pretty amazing future we have ahead of us. If the NSA ever gets the silicon grunt to do this the way they do bulk data collection, hopefully they'll suddenly change policy and decide there are limits to how detailed their "just for when you commit a crime" databasing can be.

On the bright side, body detection for VR via WiFi in a few decades.

Well, when I said "just for when you commit a crime" I really meant "just for if you commit a crime."

And the reason I said "when" instead of "if" is because they just assume all innocent people will eventually commit a crime, and this justifies a level of preemptive surveillance that Al Capone wouldn't have even been subjected to while he was actively suspected.

It's not even accurate to say they're doing it when you're "suspected" of committing a crime. It's more accurate to say they're doing it when you're "assumed" to be committing a crime, which is always.

That's not even judging their motives. It's just making a fair assessment of their method.
