A deepfake is an AI-made or AI-altered image, video or audio that looks real and makes a person say or do something that never happened.
Example
A fake video shows a politician giving a speech she never gave.
For pros
Detection tools are unreliable. Provenance data such as Content Credentials and healthy scepticism help more. The EU AI Act sets labeling duties for deepfakes.
