The Silent Spy in Your Living Room Imagine walking through your neighborhood, passing by a bustling café or a popular park, when suddenly you're identified and tracked without your knowledge.
This scenario might seem like the plot of a dystopian novel, but researchers at the Karlsruhe Institute of Technology (KIT) have demonstrated that it's possible using everyday WiFi networks.
A study presented last November at the ACM's Conference on Computer and Communications Security revealed that ordinary WiFi signals can be used to identify individuals with 99. 5% accuracy.
