Deepfake

Definition Synthetic media — typically video or audio — in which a person's likeness or voice is convincingly replaced or fabricated using AI, often without their consent. Deepfakes pose serious risks for misinformation, fraud, and non-consensual intimate imagery.

In Depth

Deepfakes are generated by face-swap models, voice cloning systems, and video diffusion models. Detection research aims to identify telltale artifacts — unnatural blinking, lighting inconsistencies, audio-visual sync errors — but the technology gap between generation and detection is widening. Legal frameworks around deepfakes are nascent; several jurisdictions have enacted laws targeting malicious uses, while digital watermarking and content provenance standards like C2PA aim to authenticate legitimate media.
