The Deepfake. Seeing is no longer believing.

A video of a person saying something they never said can now be made in minutes using software. The face moves. The voice matches. The eyes look real. The technology is called a deepfake. It uses machine learning to generate content that did not happen. The eye trusts before the brain catches up.

• Deepfakes have been used to create false political speeches, fake celebrity endorsements, and fabricated evidence.
• If a video seems too shocking or too perfect, search for the original source before sharing.
