Authenticate Any ID Document, Instantly
Document verification software that confirms an identity document is genuine, unaltered and valid — checking passports, national IDs, driver's licences and residence permits from 190+ countries in real time.
The First Test of a Genuine Identity
Document verification is the process of confirming that an identity document is authentic, unaltered and belongs to the person presenting it. It is the bedrock of identity verification and KYC — if the document is forged, every downstream check is built on sand.
One Constellation inspects each document in real time for the security features genuine IDs carry — fonts, layouts, holograms, microprint, and the machine-readable zone (MRZ) — and flags tampering, photo substitution and template forgeries. Data is extracted with OCR and cross-checked for internal consistency, then passed straight into biometric and screening steps.
