What is a fake document detector and why use one?

01

AI multiplies forgeries

A bank statement, a payslip or an ID card can be made or edited in minutes with a generative tool, with no trace visible to the eye. Insurers, lenders and KYC teams see these documents enter their processes.

5 %of manipulations or altered files spotted across 1.6 million documents processed by Koncile.
02

A direct cost for the business

An accepted forgery is a claim paid by mistake, a loan granted on invented income or a fictitious supplier paid. Manual review can no longer keep up with volume: it ties up experts and lets the best forgeries through.

03

What a fake document detector is

Software that reads every incoming document and runs it through forensic, visual and semantic checks: file metadata, editing traces, consistency of amounts, comparison with known official documents. It returns a score from 0 to 100 and the list of anomalies, so the team can decide fast.

150+checkpoints run on every document, in under three seconds per page.
Features

Why does Koncile detect document fraud differently?

Koncile built technologies to address the diversity of forgeries: specialised models for image tampering, detailed knowledge of how LLMs behave, and content consistency analysis with a reading grid designed with specialists.

Specialised machine learning models

Koncile built K-Detect, an AI detection model that spots photo edits and partial or full AI generation.

Trained on real fake documents

Koncile models learn from a set of forgeries met in real conditions, built together with our insurer, lender and audit firm customers, rather than from synthetic examples generated for training.

Comparison with official documents

Every document is compared with the known templates of its issuer: format, metadata, writing style.

Designed with industry experts

Koncile works with accountants, lawyers, compliance experts and industry specialists to identify the inconsistencies fraudsters leave behind. Faking a payslip is very complex, and almost always leaves anomalies.

Connected to 30 databases

Every document is cross checked against more than 30 external databases: company registers, banking references, vehicle databases, data leaks.

Comparison

How reliably can forgeries be detected?

On 1,200 bank statements including 400 forgeries, Koncile detects 89% of the forgeries, against 51% for the best LLM. Same test set and same threshold for every model.

LLMs are not built to detect forgeries

These general purpose models ignore fraud patterns

Customer feedback

What results do our customers get on OCR and fake documents?

Insurers, fintechs, audit firms, manufacturers and healthcare players: published case studies, video interviews and verified reviews, in Europe and the United States.

Barely three months after going live, we saved about 70% of the time spent checking documents. Between 95 and 99% of the data is read automatically by Koncile.

Ghislain AvertyChief Operating Officer, Toyota Assurances

It takes three minutes to create the Koncile button on the scanner, and the team is up and running right after. Hardware alone is no longer enough: hardware plus solution is what creates the added value.

Koncile secures the processing of our insurance documents: extraction and fraud detection make us more reliable on the statements and documents we receive.

Louis ReignierHead of production, CMAM

We receive documents from all our rental partners in very different formats. Koncile extracts and structures them down to the detail: the data arrives ready to export, with no retyping.

Pierre-Henri VernayDeputy Director, Next & Go

Before Koncile, consolidating certificates took several days. Now it takes a few hours, with 100% traceability and simpler audit preparation.

Hugo DepondDeputy Director, Bilfinger LTM Industrie

Across several million documents a year, extraction and fraud detection keep the promises we make to our customers.

Your questions on fake document detection

Short answers, with figures when we have them.

Talk to us
  1. Document fraud means producing or editing a document to obtain an undue advantage: a loan, a payout, a contract, a job. It ranges from traditional photo editing techniques to the use of AI. The practice is punishable by law.

  2. To get the best possible detection, Koncile combines machine learning models trained on fakes, the identification of fraud patterns and of digital traces left in files, and the detection of inconsistencies (e.g. amounts, totals, dates).

  3. Across 1.6 million documents processed, bank statements, payslips, invoices, ID documents or proofs of address, Koncile flagged 5% as manipulated or transformed files. We measure detection document type by document type, on test sets where the fakes are known: on scanned bank statements, for example, 89% of fakes are caught, versus 51% for the best language model. Each rate is published together with what we do not measure yet.

  4. Koncile's false positive rate is 1.5%. A poorly calibrated metadata test flags 10 to 20%, which is why Koncile calibrates every check by issuer and by channel. A verdict remains a signal to verify, not an accusation.

  5. The Advanced plan is €199 per month, about €0.20 per page, with API, SDK and MCP access. The Enterprise plan is quote based. The online checker stays free for a first document. See pricing.

  6. Yes. It is encrypted and deleted as soon as the analysis is complete unless you keep it in your history. It is never shared, sold or used to train a third party model. Koncile is SOC 2 certified. Security policy.

  7. Bank statements, payslips, invoices, identity documents, proofs of address, tax notices, company registers, prescriptions, driving licences, in around thirty countries and several languages. All documents.

  8. REST API, Python and JavaScript SDKs, webhooks and MCP server: one call returns the extraction and the score. Ecotable connected Koncile through the API in a few days. See the API.

  9. Yes, for PDFs as well as images, thanks to the known traces left by generators: 5.2% of the PDFs in our corpus are AI generated. Video deepfakes are out of scope, and we say so plainly.

  10. Yes: Koncile includes an OCR that extracts precise data, then cross checks it between documents. Identity, income, dates, addresses or bank transactions that do not match. It can also easily identify several documents within a single file.

  11. Koncile is a tool built for professionals. Banks and fintechs, insurers, KYC teams and healthcare providers: Meelo, Toyota Assurances, ADN Solutions, HealthNet Homecare, 1stKYC.

  12. Because it does not only look at the image: it cross checks the file, the image and the content, then compares each document with the known documents of its issuer, bank by bank, software by software. On 1,200 scanned statements, it detects 89% of the forgeries, against 51% for the best language model.

  13. A language model reads the document like a human in a hurry: it sees neither the file metadata, nor pixel level editing traces, nor the issuer's usual template. A clean forgery, rewritten with the right software, goes through without an alert. Purely visual tools, for their part, do not check that the amounts add up.

  14. Because they apply the same threshold to every document: a statement exported from a bank's app has unusual metadata without being fake. Without a reference by issuer and by channel, these tests produce 10 to 20% false positives. Koncile calibrates every check on what each issuer actually produces.
