Document verification

Document fraud detection API for lending and KYC.

Forged and tampered IDs clear onboarding every day. TrueSecurix validates Aadhaar, PAN and passport MRZ with deterministic checksum math, so a fabricated document is caught by arithmetic that cannot raise a false alarm.

What it catches

Forged IDs, caught by math.

Invalid Aadhaar

The Aadhaar Verhoeff checksum is verified. A number that does not satisfy the checksum is mathematically invalid, not a guess.

Malformed PAN

PAN structure and format are validated against the official pattern, flagging fabricated or mistyped identifiers.

Passport MRZ failure

The machine-readable zone is parsed and its ICAO 9303 check digits are recomputed to expose edited or forged passports.

One call

Send the ID, get a deterministic verdict.

Post the document image to /v1/verify. Checksum and format math return in milliseconds with a pass, review or flag decision and the exact reason. Because the checks are deterministic, this path cannot false-positive a genuine document.

FAQ

Document fraud detection, answered.

Which Indian documents do you validate?

Aadhaar by the Verhoeff checksum, PAN by format, and passports by the ICAO 9303 machine-readable-zone check digits. More document formats are on the roadmap.

Can a checksum check false-reject a real document?

No. A valid Aadhaar or passport MRZ always satisfies its check digits, so a correctly captured genuine document passes. The deterministic path only flags mathematically invalid inputs.

Do you verify the document against a government database?

We validate the document's own structure and checksums, and match the ID photo to the selfie. We do not claim any government-database lookup or UIDAI authorisation we do not hold.

Stop forged documents at origination.
