IIT Delhi Warns GPS Data Enables Covert Surveillance of User Activity and Environment

Imagine your phone's GPS usually tells you how to get somewhere.

But scientists at IIT Delhi found that the tiny signals your GPS uses can actually tell a lot more about what you're doing!

They created a system called AndroCon that can listen to these GPS signals, like how loud they are or how they change.

This system can figure out if you are sitting, standing, or even lying down.

It can also tell if you are on a train, in a park, or in a crowded place.

Even more surprising, it can guess if a room is full of people or empty.

It can also help draw maps of rooms inside buildings!

This is like a secret way your phone can know what's happening around you, without needing to turn on the camera or microphone.

While this could be used to make helpful apps, it also means that other apps with permission to see your location could learn these private details without you knowing.
