How do deepfakes work and why are they a growing concern?

Deepfakes use clever tricks to make videos look like real people saying things they never said.

Imagine you have a photo of your favorite cartoon character, and you want them to say "Hello!" in a video. A deepfake is like having a special robot that can take that photo and make the character talk, just like how your voice changes when you sing or shout.

Deepfakes use computer learning, which is like teaching a robot by showing it lots of examples. The robot learns how faces move when people talk, laugh, or smile. Then, it can take a photo of someone and make them say any words, even if they never said them before.

Deepfakes are like fake friends who can pretend to be your favorite teacher or parent on video. Sometimes, people use deepfakes to spread lies or trick others online, it's like when someone wears a costume and pretends to be someone else at school. As more people learn how to make deepfakes, they become harder to tell apart from real videos, making them a bigger problem.
