WiFi's Dark Secret: How Ordinary Routers Can Turn You into a Trackable Person Researchers at Karlsruher Institut für Technologie (KIT) have made a disturbing discovery: ordinary WiFi networks can identify individuals with near perfect accuracy, without the need for cameras or specialized equipment.
This technology has been tested on 197 participants and identified individuals with nearly 100% accuracy, even from different angles and regardless of how they walked. The implications are staggering.
With WiFi networks already ubiquitous in homes, offices, restaurants, and public spaces, this technology has the potential to turn every router into a de facto surveillance tool.
