Hey, did you know your phone’s light sensor might be spying on you? Tech experts found out that it can be a bit sneaky. Hackers might use it to follow your every move! They can even use fancy computer stuff to see what’s in front of your screen.
Imagine a stranger using your light sensor to check if your face or hand is in front of your smart device.
People usually say to turn on your camera only when needed. Some even cover their cameras with tape or disconnect them to keep prying eyes away.
But here’s the thing: light sensors could be another way for bad guys to spy on you. Hopefully, tech companies will make sure future devices are more secure.

Let’s talk about how someone could spy on others using light sensors. Later, I’ll explain how smart computer tech has made imaging better. Ever wondered how a light sensor can spy on people?
Well, scientists at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) created a super-smart algorithm. It can use the light sensor to see what’s happening around your screen.
Most phones use these sensors to do cool things like adjusting the screen brightness in the dark. These sensors are so good that they can notice even tiny changes in brightness.
It’s like the things around you make shadows, and the light sensor can pick up on those shadows.
This person named Yang Liu and their team used a smart computer program to turn the sensor data into pictures. Think of it like shadows on a gray background. What’s even cooler is that the computer turns these pictures into a video that moves in real time. Neat, huh?
