Rise of deepfake threats means biometric security measures won't be enough

Gartner warns that AI-generated deepfakes are increasingly capable of defeating facial biometric liveness detection, prompting doubts about the sufficiency of standalone identity verification. The report urges defense-in-depth by combining device and network telemetry (e.g., device model/camera resolution consistency, location, request frequency) with AI-based deepfake detection to spot synthetic artifacts, rather than relying on a single authentication factor.
