Summary

Document fraud involves using falsified, fabricated, or stolen identity documents to bypass verification checks, serving as a gateway to further identity crimes. These forgeries fall into four main categories: photoshopped originals, template-based counterfeits, printed-and-photographed reproductions, and AI-generated synthetic IDs. Detecting such fraud requires various techniques, including MRZ checksum validation, NFC chip authentication, visual and structural analysis, and database cross-validation. Didit's ID Verification service enhances fraud detection by processing over 200 signals in under two seconds for a minimal fee, offering extensive support for 14,000+ document types from 220+ countries. It employs a configurable workflow to adjust the stringency of checks based on risk factors, making it suitable for various industries such as fintech, crypto exchanges, gig platforms, and age-gated services, while also offering compliance with AML obligations.
