An office wants touchless entry: a camera verifies an employee's face against enrolled profiles before unlocking doors. Which service provides facial detection and verification?
A.Azure AI Vision image analysis
General image analysis doesn't do face verification.
B.Azure AI Face
Face service = purpose-built facial verification. Correct.
C.Azure AI Custom Vision
Custom Vision lacks anti-spoofing/liveness and person-verification features.
D.Azure AI Video Indexer
Video Indexer extracts insights from video — not identity verification.
Why this answer
Azure AI Face provides face detection, verification (is this the same person?), identification (who is this?), and liveness detection. Video Indexer analyzes video content broadly; Custom Vision could theoretically be trained but Face is the purpose-built service.
