Supplemental Guidance
Validation and verification of identity evidence increases the assurance that accounts and identifiers are being established for the correct user and authenticators are being bound to that user. Validation refers to the process of confirming that the evidence is genuine and authentic, and the data contained in the evidence is correct, current, and related to an individual. Verification confirms and establishes a linkage between the claimed identity and the actual existence of the user presenting the evidence. Acceptable methods for validating and verifying identity evidence are consistent with the risks to the systems, roles, and privileges associated with the users account.
Practitioner Notes
This enhancement requires validation and verification of identity evidence — not just collecting documents but confirming they are genuine and belong to the person presenting them.
Example 1: Use an automated identity verification service (like ID.me or Jumio) that checks government ID documents for tampering and matches the photo against a live selfie.
Example 2: Train your HR staff to check government IDs for security features (holograms, watermarks, UV features) and verify the photo matches the person during in-person onboarding.
