Document fraud is on the rise. In an increasingly digital business landscape where files are shared and signed online, the manipulation of critical documents has become alarmingly simple. Whether it is an invoice, a certificate or a contract the risks are real and growing. In this article we dive deeper in the five most common types of document fraud and how to prevent them.
1. Edited Invoices
Fraudsters commonly manipulate PDF invoices by changing payment details such as IBAN numbers or amounts. A subtle edit, like replacing a bank account with one under their control, can redirect thousands of euros without raising alarms. This type of fraud often targets supply chain and finance departments and can result in irreversible financial loss.
2. Fake or Swapped Product Certificates
In industries like aviation, pharma or electronics, quality and safety are everything. Fraudsters sometimes replace legitimate certificates with outdated, incomplete or fake versions. This is especially harmful in B2B environments where one incorrect certificate can delay production lines or even put lives at risk.
3. Metadata Tampering
Digital documents contain metadata: author names, creation dates, and version history. By modifying this data, malicious actors can impersonate authors, backdate contracts, or hide unauthorized changes. Most software doesn’t alert you to these edits yet they can completely undermine document integrity.
4. Cloned Compliance Documentation
Criminals sometimes replicate the layout and style of legitimate compliance documents, such as ISO certifications or customs forms, to create fake but convincing copies. These forged documents can enable smuggling, bypass import duties, or give false legitimacy to unsafe products.
5. Partial Alterations in Multi-Page Documents
One of the most insidious tactics is editing a single page or clause in a multi-page document, like a contract or tender. Because the rest of the document remains intact, these changes are difficult to spot during manual review but can alter the intent, responsibility or outcome of an agreement.

Why Traditional Methods Are Failing
Legacy methods such as watermarks, digital signatures or manual checks no longer suffice.
- Watermarks can be easily removed or overlaid.
- PDF metadata can be modified without trace.
- Digital signatures only for for traditional PDF’s and often rely on proprietary software that breaks outside of its ecosystem.
How Our Technology Prevents All Five Types of Document Fraud
Modern blockchain-based validation platforms solve the root problem: trust in the file itself.
Platforms like Trustion Validate use a cryptographic hash to create a unique fingerprint of your document. If a single character or pixel changes, the fingerprint no longer matches. This fingerprint is then stored on a public, immutable blockchain, a ledger that can’t be tampered with or hidden.
In simple terms:
- You validate a document and it gets a fingerprint.
- That fingerprint is locked on the blockchain with a timestamp.
- Later, anyone can compare the current document with the fingerprint.
- If it doesn’t match, it’s been altered.
Old methods rely on appearance. Blockchain proves integrity.
With Trustion Validate, you get:
Proof of Existence
Proof of Authenticity
Proof of Integrity
