How verification works
We control documents against blockchain anchors, embedded digital signatures, issuer databases, and 80+ external credential platforms.
The security level returned reflects the proof we find.
You submit
A URL, a credential GUID, or a PDF/image. No account required, nothing stored beyond the verification result.
We check security layers
Blockchain proof, eIDAS digital signature, PKCS#7 cryptography, issuer database, and 80+ external credential platforms.
You get a verdict
You receive clearly explained security levels, from eIDAS & blockchain-secured to unverifiable, plus the underlying proof.
Security levels
The Level reflects what kind of security was used when issuing a document. Read across to see what each level guarantees.
| Security level | Blockchain record | eIDAS signature | Issuer confirmation | Tamper-proof | Verify without issuer | Risk of fabrication |
|---|---|---|---|---|---|---|
| Signed + Secured Blockchain + eIDAS signature | ✓ | ✓ | ✓ | ✓ | ✓ | None |
| Secured Blockchain only | ✓ | — | ✓ | ✓ | ✓ | None |
| Signed Digital signature only | — | ✓ | ✓ | — | — | Low |
| Unsecured Issuer database only | — | — | ✓ | — | — | High |
| No Origin - No Security No proof found | — | — | — | — | — | Very high |
What is eIDAS, and why does it matter?
eIDAS is the EU regulation (910/2014) that defines a common framework for digital signatures across all 27 member states. A document signed with a Qualified Electronic Signature carries a verified signer identity backed by an accredited trust service provider.
TRUE Verify reads the PKCS#7 / CAdES signature embedded in PDFs, extracts the signer's identity, the issuing certificate authority, and the precise signing time, backed by RFC 3161 timestamping.
If the document also has a blockchain hash on file, you reach Level I, the strongest combination of cryptographic proof a credential can carry. Either way, Level I or II means the document is tamper-proof and verifiable for the lifetime of the credential.
