How do AI deepfakes work and how are they identified?

Deepfakes are like when someone takes your face and puts it on a different person’s body in a video, like a photo collage, but moving!

Imagine you have a robot that learns how to draw by looking at lots of pictures. This robot is called an AI (short for artificial intelligence). When making a deepfake, the AI watches many videos of a person’s face, like how they smile, blink, or talk. It learns all these little movements and copies them.

Then, the AI takes another video and changes the face in it to look just like the person it learned from. It's like having a super-smart copycat who can mimic someone so well that it looks real!

Now imagine you have a detective who checks for clues. This detective is called an expert, and they use tools or even just their eyes to find signs something isn’t quite right.

Sometimes, the AI makes small mistakes, like a face blinking too fast or moving in a funny way. These are clues that someone might be watching a deepfake instead of a real video!

If the detective is really good, they can tell if it’s a trick or not, just like you know when your friend is telling a silly story!
