What is identity verification on a background check?

5 min read · Updated August 2026

Short answer

Identity verification confirms the applicant is who they claim to be by validating a government ID and matching a live selfie to it. Doing this before any search runs eliminates the wrong-person matches that cause false-positive background reports.

Why it comes first

Every downstream search is only as good as the identity it is attached to. Traditional screening matches on name, date of birth, and SSN — identifiers that are shared, mistyped, and stolen. That is the root cause of reports containing another person's record.

What the process checks

  • Document authenticity — security features, fonts, and tampering signals on the ID.
  • Liveness — confirming a real person is present, not a photo, mask, or deepfake.
  • Face match — comparing the live capture to the document portrait.
  • SSN trace — validating issuance and associated address history.
  • Device and session signals for fraud patterns.
Ethur includes ID and biometric verification in every background check, which is how the platform holds a 0% false-positive rate on returned records.
