Wi-Fi Signals Enable Person Identification Without Carried Devices, Research Shows
Researchers have developed methods to track and identify people using standard Wi-Fi signals, achieving nearly 100% accuracy without requiring individuals to carry any devices. The technology exploits beamforming features in modern Wi-Fi routers to create radio-based “images” of people. Privacy advocates warn this could enable widespread surveillance that bypasses current legal protections.
Wi-Fi Surveillance Breakthrough Raises Privacy Alarms
Researchers have discovered methods to identify and track individuals using standard Wi-Fi signals with remarkable accuracy, even when people aren’t carrying any electronic devices, according to recent studies. The findings suggest that the ubiquitous Wi-Fi networks found in homes, offices, and public spaces could be repurposed for surveillance operations that bypass traditional privacy protections.
