About UsJobsContactFrom travel expenses to applicant tracking, HR runs on documents and images that decide payouts, hires and compensation. Generative AI now produces convincing receipts, certificates and pay slips with zero technical skill. VAARHAFT verifies every upload at the pixel level, instantly, inside the systems your teams already use.
“A photorealistic restaurant receipt takes thirty seconds and zero technical skill to generate. A fabricated reference letter takes a minute. OCR will read them. Visual review will pass them. The decision they trigger, reimbursement, hiring, salary, is real money with real consequences.”
What this means for HR operations:
VAARHAFT's Fraud Scanner analyses every receipt, certificate, scan and screenshot the moment it enters your HR stack. Suspicious items are routed for review; clean items flow through reimbursement, onboarding or approval without friction.
Diffusion models and specialised receipt generators leave statistical traces that humans cannot see. The Fraud Scanner identifies fully AI-generated documents, post-edited values, duplicate submissions and metadata anomalies, across receipts, certificates, IDs and pay slips.
Operates invisibly behind your expense app, ATS or HR suite via REST API. Employees and candidates notice nothing. HR teams receive an additional signal exactly where they already decide, no tool-switching, no separate platform.
Authentication is no longer a differentiating feature in 2026, it is becoming an expectation, the way OCR became standard a decade ago. Vendors that do not include fraud detection lose ground to those that do.
Ready to close the HR fraud gap?
Book a DemoWherever an employee or candidate submits a document or photo that drives a monetary decision, reimbursement, hire, raise, benefit claim, VAARHAFT verifies it before the workflow advances.
Travel and expense is the highest-volume HR fraud surface. Employees photograph receipts in an app, OCR extracts values, a workflow triggers reimbursement, manual sampling, if it happens at all, runs only on conspicuous amounts. In that gap, fraud thrives: fully AI-generated restaurant or taxi receipts, manipulated amounts on real ones, multi-channel duplicates (paper, scan, app), and receipts pulled straight from online review sites. VAARHAFT verifies every receipt at the moment of upload, routes suspicious items to review and lets clean ones flow through.
Receipts, scans and exports are checked the moment they enter your stack, not at month-end review. Suspicious items go to review, clean items flow through.
Diffusion models and specialised generators leave statistical traces humans cannot see. Our models read those traces, even when a receipt looks perfect.
A heatmap shows which regions of a receipt or certificate were altered, amount, item, date, stamp, not just that something is off.
A receipt resubmitted from last month, shared between colleagues from the same trip, or pulled from an online gallery, VAARHAFT flags all three patterns.
Software signatures, edit traces, and inconsistencies between claimed capture time and file characteristics, all checked and cross-referenced.
Every check produces a structured report, fit for internal audit, external review, and where needed, employment-law proceedings.
Integrates as an API behind your HR suite, expense app or ATS. Employees and candidates notice nothing. HR sees an extra signal where they already decide.
Authentication is fast becoming an expectation in HR software, like OCR a decade ago. Ship it as standard and stay ahead of the next procurement cycle.
Receive API credentials and connect to the REST endpoint. Full documentation on docs.vaarhaft.com.
Plug into the upload step inside your expense app, ATS, or HR suite. The candidate or employee experience does not change.
Receive a structured JSON verdict, authenticity score, manipulation heatmap, detected anomalies, in under 3 seconds.
Green flows through, yellow goes to review, red is blocked or escalated. Each result is logged with a PDF report for audit.

Yes. Generative diffusion models and specialised receipt generators produce images that are visually indistinguishable from real receipts but leave statistical signatures our models are trained to detect, even on perfect-looking output.
Yes. The Fraud Scanner is designed for files that have been photographed, scanned, compressed or emailed. Authenticity is analysed after digitisation, that is the entire point of the system.
No. The integration is invisible. The check runs server-side via API the moment a file enters your stack. The end-user experience does not change.
OCR reads text. Rules engines flag thresholds. Neither verifies whether a document is real or AI-generated. The Fraud Scanner adds an authenticity signal on top of what you already do.
Typical integrations into expense apps, ATS or HR suites take one development sprint. We provide full REST API documentation, sample payloads, and dedicated integration support.
Yes. Documents and images are processed within EU data centres and not retained after analysis. The service is designed in compliance with GDPR/DSGVO and applicable EU works-council expectations.
VAARHAFT runs on submitted artefacts only, not employee monitoring. It produces a signal per file, not a profile per person. We support customers in framing the rollout for works councils and providing technical-organisational documentation.
Yes. A typical pilot runs for 4–6 weeks against a sandboxed integration with a sample of historical submissions (including known fraud cases). We deliver a performance report with metrics specific to your portfolio.
We run a live demo against the exact document types your team handles and show how the API integrates into your existing expense or recruiting workflow.
