Document Authentication
Document authentication is the process of determining whether an identity document is genuine, unaltered and issued by the claimed authority, by examining its security features, data consistency and signs of tampering.
Why it matters
A convincing forgery defeats every downstream control. Authentication is the layer that separates a real document from a good imitation.
How it works
- Template matching: layout, fonts and colour profiles against the known genuine design.
- Security features: holograms, optically variable inks, micro-printing patterns and UV or IR features where the capture channel allows.
- Data consistency: visual zone against MRZ, barcode and chip.
- Integrity analysis: detection of digital manipulation, photo substitution and screen or print re-capture.
- Validity: expiry and issuer-side checks where available.
Common challenges
- Forgeries produced from stolen genuine blanks.
- Composite attacks combining a genuine document with a substituted photo.
- Capture conditions that hide or mimic features.
