KYC Document Fraud Detection API

Forensic fraud signals on the documents inside your KYC pipeline — not a replacement for identity verification.

Forensic detection delivered as one API call

One POST returns AI-generation indicators, tampering regions, metadata drift, math reconciliation, and a verdict — designed for risk engines, not onboarding funnels.

▸ 01 · The Problem

Why identity-onboarding APIs miss document-level fraud

Identity verification providers — Persona, Jumio, Onfido, Veriff, Plaid Identity — answer 'is this person who they say they are?'. They do not deeply analyse whether the bank statement, paystub, utility bill, or business document submitted during KYC was AI-generated, recycled, or tampered. Regulators increasingly expect both.

TrueDoc returns structured forensic evidence per document — MRZ checksums, ELA regions, math reconciliation, AI-generation flags, metadata drift — designed to sit behind your existing IDV provider so compliance teams have audit-ready evidence for SAR filings and regulator requests.

▸ 02 · Fraud Signals

What we look for

Cross-checked across 4+ vectors
▸ Primary signal

Synthetic identities passing data-only checks

Detected at pixel + metadata + structural layers

AI-generated IDs evading legacy template matchers

Edited statements masking source-of-funds risk

Proof-of-address forgery for sanctions evasion

What gets checked

Passports, IDs, and driver's licenses
Address proofs (utility, bank, lease)
Source-of-funds documentation
Business documents (incorporation, UBOs)

Integration patterns we recommend

Two patterns cover most production deployments. Synchronous: POST a document, block on the verdict, route the decision in your application code. Best for low-volume, user-facing flows where the reviewer needs an immediate answer.

Asynchronous: POST a document, receive an acknowledgment, then handle the signed verdict over a webhook. Best for batch ingestion, back-office review queues, and any pipeline where fintech kyc and risk engineering teams review documents minutes or hours after submission.

Latency and throughput envelope

End-to-end latency is dominated by the forensic layers, not the network. A typical PDF or image returns a verdict in ~5–9s p95. Throughput scales horizontally; teams running batch ingestion typically tune concurrency on their side and rely on webhook delivery so request timeouts are not a concern.

Rate limits, retry semantics, and the signed-webhook event schema are in the developer reference — designed so a failed downstream consumer never silently drops a verdict.

How findings map to your decision engine

Each verdict carries a trust score plus structured findings: forensic layer, signal name, severity, and (where applicable) a bounding region on the document. That maps cleanly to a rules engine — for example, "auto-reject when synthetic identities passing data-only checks is detected with high confidence" or "route to human review when only ai-generated ids evading legacy template matchers is detected."

The point: the API is built to feed a decision system, not to be one.

Run a real document. Get a forensic verdict.
