A complex solution providing verification process of electronic documents.

OBELISK Validator is a product from the OBELISK family that ensures the correct and complete process of verifying that a signed electronic document is legally valid and relevant throughout the EU in accordance with the eIDAS Regulation.

OBELISK Validator supports processing of all formats declared in eIDAS regulation and answers following questions:

  • Was a document created in a recognized format?

  • Does an electronic signature comply with required policies and limitations?

  • Was a document (signed data respectively) tampered with after an electronic signature has been created?

  • Are all the used cryptographic algorithms secure?

  • Is it possible to identify all of the signing certificates in an unambiguous and verifiable way?

  • Is a document stamped with a trustworthy electronic time stamp?

  • Were the signing certificates issued by a trustworthy certification authority?

  • Were the certificates used in electronic signature creation process valid and not revoked?

  • Are the certificates qualified?

  • Were the signatures created by a qualified signature creation device (QSCD)?

Validation process

In the perspective of the scope of facts being validated electronic signature validation process is precisely defined. But the validation results may differ depending on the assurance level requirements, or the signature properties. Results of the validation is directly influenced by a set of input parameters grouped into so called validation policy. OBELISK Validator supports specification of the validation policy (in XML) on the input of the validation along with the validated document.

The output of the validation of an electronic signature is detailed validation report in XML, which contains validation results of all evaluated attributes and properties of validated signature required by ETSI. Integral part of the validation output is a set of validation data gathered during the validation process.
