Document Fraud Detection

AI document fraud detection for lenders.

Tampering, forgery, restated income, mismatched IDs. Caught at the document layer. Not after the loan is on the books.

Kita detects document fraud at intake. We read every document in the file and flag the signals an analyst would miss when reviewing 40 files a day.

Definition

What is AI document fraud detection?

AI document fraud detection uses vision and language models to identify forged, altered, or fabricated documents at scale. It catches tampering, metadata inconsistencies, font mismatches, restated numbers, and cross-document contradictions that manual review misses when volume is high.

How it works

01

Read each document for tampering

Stamp consistency, signature placement, font matching, metadata vs. visible content, pixel-level edits. Verdict plus the specific signals that triggered it.

02

Cross-document reconciliation

Same TIN across all forms. Same revenue figure across tax return and bank statements. Same officers across SEC cert and audited financials. Mismatches surface automatically.

03

Market-calibrated patterns

Fraud patterns differ by country. We calibrate per market: PH SEC tampering, ID KTP forgeries, MX RFC mismatches, SA FICA inconsistencies, U.S. paystub edits.

Who it's for

Built for the three lender scenarios we serve.

Microfinance

High volume, thin margins.

Catch fabricated income, doctored mobile-money records, and recycled IDs at intake. Detection at scale changes the loss curve on micro-loan economics.

SME and trade finance

Restated audited financials.

Surface inconsistencies between audited financials, tax returns, and bank statements. Catch capital-structure restatements and revenue inflation.

CDFI and SBA

Document-heavy underwriting.

CDFI and SBA files involve more documents than a typical consumer loan. Fraud detection scales the diligence so analysts focus on judgment, not pattern-matching.

The product

Kita Capture

Fraud detection is built into the Kita Capture document layer. Every document parsed comes with fraud signals and a verdict, calibrated to your market and document type. No separate fraud product to integrate.

FAQ

Common questions

What kinds of document fraud does Kita detect?

Pixel-level tampering, font and stamp inconsistencies, metadata mismatches, edited PDFs, fabricated forms, restated income, mismatched identifiers across documents, recycled identity documents, and forged signatures. Verdicts come with the specific signals that triggered them.

Is document fraud detection a separate product?

No. Fraud signals are returned alongside the extracted data from every Capture API call. There is no separate fraud product to integrate. Verdicts and signals are part of the standard response.

How does cross-document verification work?

Kita reconciles values across documents in the same borrower file. Same TIN across all tax and registration forms. Same revenue across audited financials and tax returns. Same officers across SEC cert and GIS. Mismatches surface as cross-document signals.

How is fraud detection calibrated per market?

Fraud patterns differ by country. The signals tuned for Philippine SEC and BIR documents are different from those tuned for Mexican RFC and CFDI, Indonesian KTP, South African FICA, or U.S. paystubs. Kita ships calibration per region we are live in.

Can fraud detection be tuned to our risk tolerance?

Yes. The threshold for flagging a document, the weight applied to each signal, and the actions triggered on a high-confidence fraud verdict are all configurable per lender.

How do we audit fraud verdicts?

Every fraud signal cites the specific evidence: pixel coordinates of an edit, the metadata field that conflicts with the visible content, the cross-document mismatch with values. A reviewer can trace any verdict back to the underlying signal.

Does fraud detection slow down origination?

No. Fraud detection runs inline with document parsing. Sub-30-second typical end-to-end latency including fraud signals. No separate batch step.
