Electronic signature verification vs. qualified validation

Free online tools

Standard signature verification


  • Provides only a basic technical snapshot, delivering high-level general summaries instead of granular, actionable lifecycle data.

  • Does not generate formal, legally binding reports recognised by regulatory bodies or admissible as strict court or audit evidence.

  • Lacks the deep architectural verification required to satisfy long-term historical compliance standards.

Frequently Asked Questions

o Qualified Validator

Why is the built-in verification tool in popular PDF readers insufficient?

While common PDF readers show a basic technical snapshot of a signature, they cannot replace a qualified validation service. They do not provide the formal, legally binding proof required for official business and legal processes. Free readers merely offer a technical preview, not a certified trust service.

What is a Validation Certificate?

This certificate is the official output of the qualified validation process. It confirms the regulatory validity of a signature under eIDAS regulations, providing robust evidence to satisfy formal audits, legal checks and compliance procedures.

What do I receive once a document has been validated?

Upon successful validation, you will receive both an official Validation Certificate and a comprehensive validation report. These are delivered as a user-friendly, easy-to-read PDF alongside an ETSI-compliant XML report.

What is a Validation Report?

A Validation Report is a structured XML document compliant with rigorous ETSI standards. It contains complete technical data and granular cryptographic insights from the verification process. While the PDF Validation Certificate is designed for quick, convenient human review, the XML report is optimised for direct, automated processing by internal IT systems.

What exactly does qualified signature validation check?

It verifies critical compliance parameters: confirming whether the signature was valid at the exact time of signing, whether the underlying certificate was active, whether the signatory's details are accurate, and whether the document has been altered in any way.

Can I validate documents generated outside the Autenti platform?

Yes. This is a crucial requirement for organisations that receive signed documents from third parties or various external sources and need to definitively verify their authenticity before proceeding.

Does the service operate via a user interface (GUI) or an API?

The service seamlessly supports both. Qualified validation can be performed manually via our intuitive web interface (GUI) or entirely automated via our API, depending on your workflows and required level of automation. This flexibility is one of Autenti's core strengths.

When is a Validation Report required?

It is primarily used in large-scale automated workflows integrated via API, where internal IT systems must automatically retrieve, interpret and archive document verification data. It is also essential for rigorous compliance procedures and internal audits that mandate a complete technical audit trail in line with European standards.
