How AI creates and spreads false videos
AI can now make fake videos of real people saying things they never said.
Real video enters AI, which studies both faces, swaps them, and makes fake video.
In simple words
Imagine a photocopier that copies a picture but changes it to show something that never happened. AI can do this with videos and photos too.
The real definition
Deepfakes are AI-created media where a person's face or voice is replaced with another's, often without consent. Fake news is false information spread online.
Like… The face-swap filter
You know phone filters that swap your face with a friend's? Deepfakes work the same way, but much more realistic and without permission. The AI studies thousands of images to make it perfect.
But: Real filters show obvious changes. Deepfakes look real enough to fool many people.
You see it every day
Fake celebrity video
Someone creates a deepfake video of a famous actor saying bad words, then shares it online.
False news spread

People also ask
Can I tell if a video is a deepfake by just watching it?
Sometimes, but modern deepfakes look very real. Look for weird eye movements, wrong shadows, or oddly smooth skin. Detection tools are getting better, but they are not perfect yet.
Is it illegal to make a deepfake of someone?
In many countries, yes—especially if you use it to hurt someone or commit fraud. Laws are still being written as deepfake technology grows.
How can I protect myself from deepfakes?
Check sources, look for official statements, and use fact-checking websites. Be skeptical of videos that make you angry or surprised very quickly.
