One fraudulent onboarding can undo months of compliance work.
Identity fraud is increasingly sophisticated. AI-generated IDs, photo-swapped passports, and digitally composited documents now pass visual inspection with ease. By the time a fraudulent customer is flagged — often during an audit or incident — the damage is already done. TamperCheck gives your onboarding team a forensic layer that catches what the human eye misses.

The problem
What fraud looks like in kyc & identity verification
AI-generated identity documents
Generative AI tools now produce convincing passports and ID cards that include realistic fonts, holograms, and MRZ data. They pass visual inspection but fail on pixel-level forensics — noise patterns, compression artifacts, and spectral analysis expose them.
Photo zone substitution
Legitimate documents with a replaced portrait zone. The original document is genuine; only the photo has been swapped. Boundary contrast analysis, sharpness gradients, and compression mismatch in the portrait region reveal the edit.
Date and field tampering
Date of birth, expiry dates, and ID numbers are the most commonly altered fields. Font inconsistencies, spacing anomalies, and metadata mismatches between the visual layer and embedded data expose these changes.
How TamperCheck helps

The result is a plain-English verdict with pinpointed findings, so your compliance team knows exactly what to look at, not just that something is flagged.
