A hot potato: As Wi-Fi spreads everywhere, a new technology could identify you just by how your body disturbs wireless signals – no cameras, no devices needed. This breakthrough raises urgent questions about privacy in a world where invisible tracking might soon become routine.
Researchers at La Sapienza University of Rome have developed a method they say can re-identify individuals based solely on how their bodies disrupt Wi-Fi signals – a breakthrough likely to reignite debates over privacy and surveillance. The technique is more powerful and less invasive than biometric systems that rely on faces, fingerprints, or mobile devices, and unlike fixed-location cameras or scanners, it can track individuals across any space covered by a Wi-Fi network.
