Now They Can Actually Use WiFi "To See People Through Walls"

•, by Michael

I wish that wasn't true, but this is the reality of the world in which we now live.  The "Big Brother surveillance grid" is constantly growing and evolving all around us, and those that are using it to watch, monitor, track, influence and control us have an insatiable appetite for more data.  They are constantly pushing the envelope, and most people don't seem to care.  But if we don't stand up for our rights now, eventually we will find ourselves living in a society where there is absolutely no privacy at all.

In fact, many would argue that we are already there.

Recently, I was horrified to learn that researchers have been working on a way to use WiFi to look through the walls of our homes to see what we are doing.  The following is a brief excerpt from a Vice article entitled "Scientists Are Getting Eerily Good at Using WiFi to 'See' People Through Walls in Detail"

Researchers at Carnegie Mellon University developed a method for detecting the three dimensional shape and movements of human bodies in a room, using only WiFi routers.

To do this, they used DensePose, a system for mapping all of the pixels on the surface of a human body in a photo. DensePose was developed by London-based researchers and Facebook's AI researchers. From there, according to their recently-uploaded preprint paper published on arXiv, they developed a deep neural network that maps WiFi signals' phase and amplitude sent and received by routers to coordinates on human bodies.
