Definition
Security approaches that confirm who someone really is using methods that can't be faked by an AI-generated voice or video clone — for example, cryptographic proof or multi-step verification — instead of just trusting how a person looks or sounds on a call. This shifts organizations away from 'I recognize that face/voice' toward 'this identity is cryptographically proven.'
Why it matters
Deepfake-enabled fraud (fake executives on video calls authorizing wire transfers, for instance) is rising fast, and any authorization process that still relies on visual or audio recognition alone is now a serious financial and security exposure.
