Deepfake
Synthetic audio or video that convincingly depicts a real person doing or saying something they did not.
Deepfakes combine generative video or voice cloning with a real person’s likeness. Detection is unreliable and getting worse, so the practical defences are provenance signals, verification channels, and organisational process. The EU AI Act imposes disclosure obligations on this kind of content.
In practice: A cloned CEO voice on a call authorising a wire transfer.
