Multi-account prevention

verifications powering the network.
One Face, One Contract — starting at registration.
Documents can be forged. Emails are free. Devices are shared. The only thing a fraudster can't duplicate is their face. Multi-Account Prevention runs a 1:N biometric search at the moment of sign-up, cross-referencing the new face against every existing record in your base. If this person already has an account — they don't get a second one.
No rules to configure. No velocity checks to tune. A deterministic answer based on biometric uniqueness.
Behind the seamless experience.
Also supports retroactive base cleanup — ingest your historical selfie base to detect duplicates already in your system.
Liveness
Step one:
Confirms a real person is present at the moment of registration. Blocks bots, deepfakes, and non-human input before the biometric search even begins.
Multi accounts 1:N
Step two:
Performs a segmented biometric search across your entire registration base. Cross-references the new face against all records in the same segment. If the biometric is already linked to a different account — it's flagged before the registration completes.
