How it Works

This anti-fraud service operates on your private, encrypted database of verified user biometrics. When a new user is onboarded, their live selfie's biometric template is compared at high speed against every template in your database and any custom blocklists. If a match is found that exceeds the similarity threshold you configure in the Didit Console, the system instantly flags the attempt, allowing you to automatically block duplicate accounts and organized fraud rings.
