DigitalSign, as a Qualified Trust Services Provider, created Verify – a qualified service for validating qualified electronic signatures or qualified electronic seals – where it is possible to verify whether a qualified electronic signature or a qualified electronic seal affixed to an electronic document are, in fact, valid, under the terms set out in Regulation No. 910/2014 (eIDAS Regulation). This validation is immediate, safe, simple and effective, being available on the user's screen.

In order to carry out a validation of a qualified certificate, the user must submit the electronic document(s) in question into Verify. After this submission, the validator will display one or more immediate result(s) on the user's screen, where it will be possible to verify whether the qualified certificate is valid or invalid.

After the user places the electronic documents he wants to validate in Verify , it will automatically show one of three possible results:

TOTAL-PASSED: When cryptographic checks of the signature (including checks of hashes of individual data objects that have been indirectly signed) are successful, as well as all checks prescribed by the signature validation policy have passed. That is, the qualified electronic signature or qualified electronic seal is valid.

TOTAL-FAILED: Cryptographic checks of the signature failed (including checks of hashes of individual data objects that were indirectly signed), or the signature certificate is proven to be invalid at the time of signature creation, or because the signature is not in compliance with one of the core standards, as the cryptographic verification building block is unable to process it. That is, the qualified electronic signature or qualified electronic seal is invalid.

INDETERMINATED: the results of the checks carried out do not allow checking whether the signature is valid or invalid. However, if this is the result, then it means that this is not a valid qualified certificate.

A validation report is a document that demonstrates the results from the validation carried out, which can be used as proof that the signatures and seals present in a document were valid from the date of its creation, until the moment in which the validation was carried out.

Verify provides two reports related to the validation process:

Summary Report : this report allows the user to have access to information about the validation process of a certain qualified certificate in a simplified way.

Detailed Report : this report allows the user to check all details of the validation process in detail, namely at a technical level.

For each document, all qualified certificates attached to it are validated. In addition, each one may have its own validation result.

No, it is possible to insert one or more electronic documents at once, all of which will be validated and displayed on the user's screen.

If the electronic document has two or more qualified certificates, after their validation, there is the possibility that not all of them are valid and, for this reason, they will present different results, despite being attached to the same electronic document.

Any qualifying validation service must provide its services using a validation policy. This policy defines the set of validation constraints to be used to validate Qualified Electronic Signatures or Qualified Electronic Seals entered and processed by Verify.

DigitalSign carries out an initial processing of personal data, namely, when the electronic document is uploaded by the data subject in Verify . However, all submitted electronic documents are deleted immediately after completing the validation process, and no further processing of any information regarding the content of submitted files, namely personal data, is carried out.
