Recently, researchers developed a technology for tracking and identifying specific people using Wi-Fi signals. The remarkable work is called WhoFi, an intelligent system that indicates who is present at a certain location and how they move via the very analysis of WiFi waves. Provoked many serious issues such as security, surveillance, and personal privacy.

WhoFi

How does WhoFi work?

It's basically just understanding how wi-fi signals reflect and get distorted by individuals. A body will affect the wi-fi signals depending on the person, and the particular person will be isolated by the system itself. According to him, the clues are in how the WiFi router signal changes when it gets reflected around and altered with the movement of a person.

Neither Camera nor Sensor Was Involved

The biggest of all is that WhoFi does not need any external sensors or cameras, or GPS attachments to work. Just a normal Wi-Fi router and an AI-based algorithm are enough. It collects information based on the proper WiFi devices being used in the house, and it tracks the movements of specific people.

Security and privacy issues

On the other hand, if this advanced technology can do wonders in security systems, it would also offer great challenges in protecting an individual's privacy. Tracking someone's movement without their consent is against human rights and personal privacy. Most of the tech analysts also term this technology as the dawn of "silent monitoring" or "covert monitoring".

Applications for This Technology

WhoFi can be used for monitoring by security forces, smart home systems, elderly health monitoring, and even by retailers to understand how much time a customer spends at a location. However, strict policies for misuse are urgently needed.

Indeed, WhoFi is a technological landmark, but it raises a problem regarding our digital privacy. Tracking people through WiFi signals creates real opportunities, but with it also comes misuse and abuse. Only time will tell where this technology leads in the future – for now, though, keeping it well at the top of our minds seems to be of utmost importance.
