Access to Closd is by invitation only: Users are authenticated through their email address and a secure password. Our system detects and prevents concurrent logins from two separate sessions.
2-factor authentication or Single Sign-On can be implemented to further reinforce security at login.
For users that need to sign documents electronically, two additional layers of security contribute to guaranteeing the identity of the signatory:
• An automated ID document verification is performed to cross check the user’s profile and detect traces of tampering with the document;
• A one-time password is sent by SMS to the number that the user registered as their mobile phone.
Users’ personal data is deleted upon request or when the personal account is deleted.
Data allowing precise identification of signatories is stored by Closd during the entire period during which the validity and probative value of the documents can be questioned by a party or a third party, in order to ensure, if needed, the exercise or defense of users’ legal claims.
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 signed document in time.
The high level of security for Advanced signatures is attained through the following steps:
• Integrating the technologies developed by DocuSign et Certeurope, providers certified by the European Commision. On each project, users can choose between the two technologies and keep the same interface and signature workflow.
• Combining these technologies with a strong three-layer authentication.
Handwritten scanned signatures are valid for signature in counterparts, for the most part used in common law countries. Closd automatically extracts signature pages and allows compliance with UK Mercury case law, which requires that the full document be sent along with signature pages.
You can use and combine different signature technologies and types in one signing session.
