How our fraud detection works

Contextual Consistency Check

With industry experts, lawyers and accountants, we’ve built specific AI models that embedd the knowledge to capture inconsistencies.
  • OCR extraction
  • Business-rule intelligence
  • Regulatory awareness
  • Cross-field validation

Forensic Detection Layer

Advanced forensic analysis to detect subtle image manipulation, tampered layers and synthetic edits invisible to the human eye.
  • Layer analysis
  • Compression artefacts
  • Pixel anomalies
  • Font inconsistencies

Metadata Analysis

Metadata never lies. Until it does. Koncile provides deep analysis to detect document history inconsistencies and suspicious edit traces embedded in the file itself.
  • Creation software mismatch
  • Edited timestamps
  • Embedded object inconsistencies
  • PDF producer anomalies

Document deepfakes: catch the fakes slipping past your checks (2026)

In 2026, document fraud has a new face: the document deepfake, a fake generated entirely by AI. According to Shufti's Identity Fraud Index 2026, it's the fastest-growing fraud category, with an annualized increase estimated at nearly 3,900%. What sets these fakes apart: they're clean on the surface. Here's how to detect the ones still slipping past your checks.

OpenCV in Python: Detecting Document Fraud Through Image Analysis

OpenCV is one of the most widely used computer vision libraries in Python. But can it really detect document fraud? In this article, we test OpenCV on several real-world falsification scenarios: amount modification, signature copy-paste, inpainting removal, and compression analysis (ELA). The objective is simple: understand what visual detection can actually identify and where its limits are.

Invoice fraud : how to detect fake invoices and suspicious suppliers

Invoice fraud is often perceived as a marginal or exceptional risk. In reality, it is one of the most common sources of financial loss for organizations of all sizes. Fake invoices, supplier impersonation, payment diversion, and subtle manipulation of approval processes continue to bypass traditional controls. While some cases are caused by simple billing errors, invoice fraud is intentional by nature. It relies on small inconsistencies, operational pressure, and trust in documents that appear legitimate. Understanding how invoice fraud works is the first step toward detecting it before payment.

FAQ

Your questions about fraud detection

Document fraud detection refers to the automated identification of falsified, altered, or forged documents, invoices, payslips, bank statements, contracts, or ID documents, submitted to an organisation. As document volumes grow, manual review becomes impractical, making automated fraud detection an essential layer of financial and operational control.

A document fraud detection tool analyses incoming documents to flag signs of tampering or inconsistency. Unlike manual checks, it processes high volumes in real time, combining business rules, reference data, and analytical models to surface suspicious documents before they generate financial exposure.

Most fraud detection tools rely on pattern matching alone. Koncile takes a contextual approach: for each document type, the platform develops specific models alongside domain experts (accountants, legal specialists, operations teams), who encode the rules and logic relevant to each context, enabling coherence checks the way a human expert would. Rather than simply flagging PDF alterations or abnormal patterns, it evaluates whether a document's data is reliable as a whole, cross-referencing figures against each other and against sector-specific rules.

The most targeted documents are supplier invoices, payslips, bank statements, contracts, and administrative certificates. Document fraud affects every sector, but is particularly prevalent in finance, HR, and procurement, anywhere high-value decisions rely on document-based evidence.

La fausse fiche de paie est l'un des documents les plus falsifiés, notamment dans les dossiers de crédit ou de location. Koncile s'appuie sur deux niveaux de contrôle : d'abord l'analyse des métadonnées du fichier, où les modifications laissent souvent des traces très visibles ; ensuite la vérification de cohérence des montants, cotisations, brut, net, qui nécessite une connaissance fine des règles de paie françaises. C'est pourquoi Koncile a été conçu avec des experts métiers : pour que ces contrôles réglementaires soient fiables et directement opérationnels.

Two integration modes are available. Via the platform, documents are uploaded directly and Koncile returns a reliability score for each one, with automatic alerts triggered on high-risk files. Via API, documents are sent to Koncile's endpoint and the score and alerts are returned in real time, for seamless integration into your existing workflows.

Effective detection relies on two complementary levels: file metadata analysis, which reveals traces of modification, and semantic verification of the document's content, which catches internal inconsistencies even when the document appears intact on the surface. It is also essential to define rules specific to each document type. On a payslip, for instance, the relationships between gross pay, net pay, and contributions follow precise rules that the tool must understand. That is why Koncile builds its models with domain experts, ensuring controls that are reliable and operational from day one. Finally, detection must cover the entire incoming document flow, not just the documents that appear suspicious at first glance.

Implementation starts with choosing the integration mode: direct access via the platform, or an API connection to plug Koncile into the organization's existing systems (ERP, HRIS, credit portal…). This integration is compatible with automation tools such as Zapier, n8n, or Power Automate. The next step is configuring the control rules specific to each document type, which is done in plain language, with no custom development required. At Koncile, this configuration is carried out with the relevant domain experts : finance, HR, and compliance. To ensure the models are reliable and fully operational from the very first day.
