Just a quick, did-you-know type of post written because the technology below is way to cool not to share 🙂

1. Did you know that the wi-fi routers can be used to identify faces, recognize keys that you type or read lips?

Researchers from the Northwestern Polytechnical University in China used WiFi signals to identify people. This identification was made based on the shape of people that was read as radio waves bounced back and forth, as well as by the specific way in which people moved. The success ratio was 88.9% to 94.5% in a domestic environment. One potential application is that of having a super custom-made smart home which adjusts lighting, temperature and even music based on the person(s) gait walking through the room. Or you can just use it to spy.

A system developed at the University of Berkeley uses distortions and reflections in Wi-Fi signals made by moving mouths to essentially lip-read. This setup was used to tell which words a single person was speaking with 91 percent accuracy. The accuracy was 74 percent when three people were speaking at the same time.
