QES: The Golden Standard in digital signatures

The essential characteristics of a valid digital signature

‍

A digital signature is the electronic counterpart of a handwritten signature, but not all digital signatures are equal. To be considered valid and reliable, a digital signature must meet specific criteria:

• Authenticity: The signature must verify the identity of the signer.
• Integrity: The signature must ensure that the document has not been altered since signing.
• Non-repudiation: The signer should not be able to deny the signature later.

‍

The exceptional qualities of QES signatures

Qualified electronic signatures (QES) represent the highest standard in digital signatures. They are not only legally valid but are also equated to handwritten signatures for documents with significant legal consequences, such as notarial deeds, mortgage deeds, insurance policies, and certain employment agreements.

How to set up a digital signature (QES)

To create or obtain a digital signature (QES), you need a Qualified Signature Creation Device (QSCD). An accredited certification authority, such as Unifiedpost with their Sign solution, can assist you with this. Unifiedpost is a trusted eIDAS service partner.

The importance of identity verification

A core aspect of QES signatures is carefully verifying the identity of the signer. This is typically done through in-person meetings or equivalent processes, such as video conferences. Only after thorough identity verification can an individual obtain their first QES. Additionally, multi-factor authentication is always required. This means the signer must go through additional security layers, such as entering a PIN code to verify validity.

When does your corporate need a QES?

QES signatures are especially relevant in situations with significant legal consequences, such as:

• Large commercial agreements
• Critical sales contracts
• Mortgage documents
• …
