eIDAS stands for 'electronic IDentification, Authentication and trust Services'. It is a European regulation that classifies digital signatures. Since 2016, a Qualified Electronic Signature (QES) has been legally equivalent to a signature on paper throughout the EU.
Three levels
- Simple: for example a name under an email. Low evidential value
- Advanced: uniquely linked to the signatory, with an integrity check. Medium evidential value
- Qualified (QES): advanced, plus issued with a qualified certificate from a trusted issuer. Legally equivalent to paper
What makes a QES unique
The signatory is rigorously verified in advance. The certificate is issued by a certified Trust Service Provider. The signature is cryptographically recorded at the moment of signing, so any later changes are detectable. And there is a long-term audit trail.
How we use QES
After your identification via Sumsub you receive a digital certificate. When you sign the articles of association, you use it to place a QES. The document is sealed immediately. The notary can easily verify the signature and its certificate, instead of having to check a paper document.
