Ordinary WiFi can now identify you with near-perfect accuracy
Summary
ScienceDaily reports that KIT researchers have demonstrated that ordinary WiFi signals can identify people with near-perfect accuracy using beamforming feedback information, potentially turning everyday networks into surveillance tools. The method uses standard WiFi hardware without special sensors or cameras, and tests with 197 participants showed identification accuracy approaching 100%. The article highlights privacy risks and urges protective measures in future WiFi standards.
