Ordinary WiFi can now identify you with near-perfect accuracy
Ordinary WiFi networks could quietly become powerful surveillance tools, allowing people to be identified without cameras, special sensors, or even carrying a connected device. Researchers showed that unencrypted signals routinely exchanged between WiFi devices and routers can be used to create radio-based images of people and recognize them within seconds. In tests involving 197 participants, the system identified individuals with nearly 100% accuracy, even from different angles and regardless of how they walked.
Summary
Researchers have demonstrated that standard WiFi networks can be used to identify individuals with remarkable precision, relying solely on the unencrypted signals exchanged between devices and routers. This breakthrough raises significant privacy concerns as it allows for recognition without the need for cameras or connected devices.
