Face authentication for entry: how Live Face works

20 Jun 2026 6 min read

Verifying that a credential is genuine answers half the question. The other half is: does it belong to the person standing in front of you? Face authentication — Live Face — closes that gap by matching a live selfie to the photo in the verified identity record.

What Live Face is

When you verify a visitor against Aadhaar or DigiLocker, the signed record includes their photo. Live Face captures a quick selfie at check-in and compares it to that photo, returning a match score. It ties the verified identity to the actual person, so a borrowed or stolen credential doesn't get someone through the door.

Why it matters

  • Stops credential sharing — the document and the face have to match.
  • Raises assurance for high-risk sites without slowing entry much.
  • Adds a visual record to the visit log alongside the verified identity.

How it works at check-in

  • The visitor is verified against Aadhaar (online or offline) or DigiLocker.
  • A live selfie is captured at the kiosk or device.
  • The selfie is matched to the photo in the signed record, with a score.
  • High-confidence matches pass; the rest escalate to a person to review.

Privacy by design

Face matching is consent-based and purpose-limited — used to confirm the visit, not to build a database. Combined with the fact that the full Aadhaar number is never stored, it fits the expectations of the DPDP Act.
