What it entails

Synthetic Identity Checks compare provided names, addresses, emails, phone numbers, and social profiles, etc against authoritative records. They include first/last/full name discrepancies, address-line mismatches, email/phone/social profile inconsistencies, and birthday vs. age conflicts. Excessive device and IP connectivity metrics further flag unnatural identity linkages.

Why it works

Fraudsters craft synthetic profiles by merging fragments of real identities with fabricated data, resulting in mismatched attributes and abnormal network link patterns—hallmarks of identity fabrication.
