What type of electronic signature does Closd offer?

Three types of signature are available on Closd: Simple and Advanced electronic signatures, and Handwritten “wet-ink” signatures. Simple and Advanced electronic signatures are equally valid under the eIDAS EU regulation. They vary in the level of authentication required for signatories, hence in the probative force, or body of proof of the signatory’s identity, of the

What is the legal framework in Europe?

Under European law, the eIDAS regulation of July 23, 2014 was a game changer, making it easy to prove that electronic signature technology is secure and reliable. It implemented a new, harmonized framework for digital trust services (among which electronic signature) and provides that national courts cannot reject electronic signatures as evidence. The eIDAS regulation

What is the validity of different types of electronic signatures on Closd?

Legally, there is no difference in terms of validity between “Simple”, “Advanced” and “Qualified” signatures. Their legal effect and admissibility in court cannot be denied in any state within the European Union. The “Qualified” signature simply benefits from a presumption of reliability. The “Simple” signature is, by default, that which does not meet the requirements of the

Should documents be initialed?

No. Electronic signature technologies play the same role as notarial binding (thanks to the document’s digital “fingerprint”). Therefore, any modification of an electronically signed document subsequent to its signature is automatically detected by the PDF reader in which it is opened. If the document was modified, a message appears warning the user that the affixed

What is the technology behind electronic signatures?

An electronic signature is composed of electronic data and leaves no graphic representation on the document. Electronic signatures’ validity and probative force lie in the digital data incorporated into the document, which guarantee its integrity and the signatory’s identity. This is done through the issuance of: (1) A digital certificate that proves that the signatory’s identity has

How can you check that a document has been validly signed and has not been subsequently modified?

A PDF reader (such as Adobe Acrobat Reader) can verify the validity of an electronic signature. When the document is opened, the PDF reader automatically performs two operations: It calculates the document’s fingerprint to see if it matches the fingerprint of the document that was signed; It checks the digital certificate to ensure its validity

How are signatories authenticated?

“Advanced” level electronic signatures require strong authentication of signatories, providing a high level of security when signing more sensitive documents. This consists of a three-layer authentication process: Personal account protected by a secure password chosen after receiving an invitation to Closd; Automated ID verification: Before their first signature on Closd, signatories must upload a picture or scan

How can you prove that this authentication has been carried out?

An authentication certificate is issued and archived by Closd upon each ID verification and electronic signature. This document gathers technical information relating to the ID verification (for Advanced signature) and to the electronic signature (envelope number, signatory’s email address, IP address, time and date, technology used, etc.). This authentication certificate is provided to users along

Can you trust the electronic signature?

An electronic signature made with a system as secure as Closd’s is more reliable than a handwritten signature. The entry into force of the eIDAS regulation has been a giant step in its generalization: The certification of an electronic signature provider is a trust factor and a guarantee of compliance with the rules established by European
