Wi-fi Signals Can Actual Reveal Your Password …

There are some things in science that you think are so unbelievable that they are just not possible. So, did you know that you can detect someone’s breathing and heart rate, even if you are in the next room? Well you can, as the breathing and skin movements affect the propagation of wi-fi signals, and the changes in the wi-fi signal can be detected for even the smallest of movements:

In 2016, researchers from Shanghai Jaio Tong University, University of Massachusetts at Boston, and the University of South Florida have shown that it is possible that a radio signal can reveal your password [here]:

With this they are able to get the PIN number right for 81.7% of the time the reflections of wi-fi signals. It uses a beam-forming wireless antenna (with Multiple-Input, Multiple-Output — MIMO), and where a radio wave is created to detect movements of a user’s hand. With MIMO, we can receive a signal from several…
