New research from the MIT Computer Science and Artificial Intelligence Laboratory paves the way for password-free WiFi technology that is safer than existing methods. WiFi passwords can often be an annoyance and are not always sufficient to protect your network from unwanted intruders and freeloaders.
The research team consists of Dina Katabi and Deepak Vasisht of MIT CSAIL as well as Swarun Kumar from Carnegie Mellon University. They developed a system named Chronos, which enables "decimeter-level localization with a single WiFi access point." In other words, it's a WiFi entry point that can specifically pinpoint all the adaptors connected to it. The WiFi technology could give a router access based on the user's precise location and make it more difficult for an Internet thief to poach remotely.
