Does this sound like a scene straight out of a spy movie? Imagine walking through your home, a mall, or even your office, and the Wi-Fi “knows” you’re there—no cameras, microphones, or even your smartphone needed! This isn’t science fiction anymore. Researchers in Italy have developed a tech called “WhoFi” that can recognise and track people using just Wi-Fi signals. Yes, the same Wi-Fi that helps you binge-watch cricket or scroll Instagram.
How Does It Work?
Whenever you move around, your body disturbs the Wi-Fi signals flowing around you. WhoFi measures those tiny, unique changes—like how your shape or size bounces or absorbs the signals. Think of it like your shadow on the wall, but invisible and picked up by advanced sensors. Using smart neural networks (think: AI with a good memory), WhoFi can identify you based just on your presence and motion.
Why Should People in India Care?
India is becoming a digital powerhouse. From smart cities in Gujarat to tech-savvy apartments in Bengaluru, Wi-Fi is everywhere. Here’s how this tech might affect us:
Pros:
Imagine a security system that recognises residents and shooes off unwanted visitors, all without peeking through your private camera feed.
Health tech: Hospitals or elderly care centres could monitor if someone falls or stops moving.
Smart homes that adapt the lights and temperature just for you—no touching switches!
Cons:
Privacy concerns are real. With great tech comes great responsibility, or rather, the risk of misuse. WhoFi can track people without their knowledge; imagine offices or landlords monitoring movements secretly.
We already struggle with privacy (think: those annoying spam calls or unknown WhatsApp groups). Unregulated Wi-Fi tracking could make it worse, unless strong laws step in.
But… Is This Tech Available Here?
Not yet! WhoFi is still being tested in laboratories and isn’t up for sale, so you won’t suddenly find your Wi-Fi router tattling on you tomorrow. But with India’s huge market and love for smart gadgets, it may arrive sooner than we think.
Final Thoughts
Indians rapidly adapt to new tech—whether it’s UPI payments or smart home devices. WhoFi could make life easier or riskier, depending on rules and how it’s used. The key? Awareness and regulation. Next time you connect to Wi-Fi, just know it might be paying closer attention than you think!
