Built for teams that rely on PDFs
One structural PDF forensics engine, applied to the document types and fraud patterns most common in your workflow. Pick the solution closest to your role — or check any PDF right now.
HTPBE analyzes the structural layer of the PDF file — the layer that records every edit, even invisible ones. We don’t inspect holograms, phone photos, or ID biometrics. If your fraud problem is a digitally altered PDF, we’re the most specific tool for it.
Ten verticals, one engine
Each page below reframes the same structural PDF forensics for a different buyer and document set.
Alternative Lending
The bank statement your underwriter approved may have been edited after download
Invoice Fraud
The invoice came from a vendor you’ve paid for three years. One field was changed before it reached you
Tenant Screening
Fake proof-of-income is how bad tenants get keys
Mortgage Underwriting
Income documents are the last unverified layer in your file
Insurance Claims
Staged claims don’t announce themselves.Tampered invoices do
Accounts Payable
Your AP pipeline processes thousands of invoices monthly. One altered bank detail routes a wire to a criminal
KYC & Onboarding
KYC verifies the person. HTPBE verifies the paperwork behind them
Expense Reimbursement
Employees don’t forge receipts anymore.They regenerate them
HR & Hiring
A fabricated offer letter is cheap. A fraudulent hire is not
Legal Contracts
Modifications after signature look the same on paper.The PDF structure doesn’t lie
One REST call, one deterministic verdict
Upload the PDF. The API returns INTACT, MODIFIED, or INCONCLUSIVE with named markers — in about three seconds.
Five forensic layers, one deterministic verdict
Every PDF we receive passes through the same structural pipeline — no model training, no thresholds to tune.
Metadata analysis
Creation and modification timestamps, producer and creator fields, XMP metadata — the first layer exposes basic tampering.
File structure
Xref tables, trailer chain, incremental updates. Any edit after export leaves a structural fingerprint here.
Digital signatures
Signature chain integrity and post-signature modifications produce deterministic markers. Certainty-level signal.
Content integrity
Fonts, objects, embedded content, page assembly. Multi-session edits and inserted objects are visible at this layer.
Verdict with markers
Deterministic output: INTACT / MODIFIED / INCONCLUSIVE, with named markers for every finding — suitable for audit trail.
Customer Stories
Teams that stopped document fraud
Compliance, finance, and risk teams use HTPBE to catch manipulated PDFs before they become costly mistakes.
Caught an invoice where the total had been changed by less than a thousand dollars. Without this I would have approved it without a second look.
Sarah M.
AP Manager
United States
We had three applicants in the same week with bank statements that looked completely fine. Two of them were flagged as modified. You simply cannot see this by reading the document — it is in the file structure.
Lars V.
Risk Analyst, Online Lending
Netherlands
Salary slips were coming with altered figures. We identified two problematic files before the placement was finalised.
Priya K.
HR Operations Lead
India
Since we started checking documents this way, we stopped two applications early in the process that would have been very difficult to reverse later.
Julien R.
Fraud Analyst, Fintech
France
Some applicants were sending PDFs that looked authentic but had been edited in ways not visible to the eye. We now ask for verified originals when something is flagged. Already saved us from a few bad decisions.
Marta S.
Compliance Coordinator
Spain
One invoice was caught because there was a mismatch between the document dates and structure. That particular case would have cost us significantly.

A deterministic verdict — INTACT, MODIFIED, or INCONCLUSIVE — plus named structural markers explaining why. No numerical risk score. Suitable for audit trail and automated decisioning.
No — it complements them. KYC platforms verify the person behind the documents. HTPBE verifies the PDF files themselves were not edited after issuance. You typically run both.
