Remember when we talked about this technology's next-gen potential six months ago? Well, it’s already more advanced — and it’s a major privacy issue.
Researchers at La Sapienza University in Rome have introduced “WhoFi,” a system that tracks individuals with incredible accuracy — up to 95.5% — by analyzing how Wi-Fi signals bounce off their bodies.
Unlike previous systems that struggled to reach 75% accuracy, WhoFi uses a neural network that allows it to “see” through walls and work regardless of lighting.
What’s particularly alarming is that it runs on standard TP-Link routers, turning regular Wi-Fi hardware into a powerful tracking device. It works by creating unique “fingerprints” for people based on how Wi-Fi signals interact with their body shape and movements. Even when participants wore different clothing, the system could still distinguish between them with remarkable accuracy.
As we’ve noted, once 6G networks are in place, this tech could evolve even further — identifying facial expressions to determine emotions, provided they’re visible. The implications for privacy are staggering. Wi-Fi-based passive monitoring, without cameras or consent, could dramatically change how personal spaces are tracked. And let's be honest, governments may say they won’t track people, but don’t be surprised if they do.
History has shown that once these unethical practices are uncovered, the typical excuse will be “national security.”
