What Is a Deepfake?
A deepfake is an image, video, or audio recording created or altered with AI to realistically show someone saying or doing something they never said or did. The term combines “deep learning” and “fake.” Deepfakes can be used for entertainment and film, but also for fraud and misinformation.
Warning Signs
Unnatural blinking or lip movement, inconsistent lighting or shadows, blurred edges around the face, and audio that sounds slightly flat can be clues, although high-quality deepfakes may show none.
Protecting Against Scams
Verifying unusual requests through a separate, trusted channel — for example calling a known number — is a common safeguard against voice or video impersonation.
