WiFi Signals Identify Individuals with Near-Perfect Accuracy
TL;DR. Researchers at KIT developed a system identifying individuals using ordinary WiFi signals with almost 100% accuracy, creating radio-based human images. - The method eliminates the need for cameras, special sensors, or carrying connected devices for identification. - Tests involved 197 participants, demonstrating accuracy across different angles and walking styles. - Unencrypted signals between WiFi devices and routers enable this advanced surveillance capability.
- KIT researchers developed a system that uses unencrypted WiFi signals to identify people.
- The system creates radio-based images of individuals without cameras or special sensors.
- It achieved nearly 100% accuracy in tests with 197 participants, even from different angles.
- This technology could turn everyday WiFi networks into powerful, invisible surveillance tools.
