Wifi Networks Can Now Identify Who You Are Through Walls

Who needs a peep hole when a wifi network will do? Researchers from MIT have developed technology that uses wireless signals to see your silhouette through a wall—and it can even tell you apart from other people, too.

There is, of course, an elephant in the room here that you wouldn’t even need RF-Capture to identify — and that’s privacy. First off, the team insists that any device using this kind of technology, such as a router that can tell when your relative has fallen, uses encryption from the get-go. “We [also] want to ensure that people do not use it for malicious purposes,” adds Katabi. “To that end, we are working along two fronts: first, we are designing blockers that can prevent someone from being tracked except by their own device. And, second, we need to have regulations that dictate how and when these devices can be used.

Privacy is always a chief concern.”
