About Concord’s Electronic Signature Validity

E-signature Compliance

How concord ensures signature legality around the world

For more than 15 years, electronic signatures have been fully valid and legally binding in most countries around the world. They are now used by individuals, companies, and governments alike to increase the speed and security of their transactions.

Used for document signatures in more than 110 countries around the world, Concord’s technology and e-signature system have been designed to meet the key requirements of all major regulations in the world, such as the U.S. Electronic Signature in Global and National Commerce Act of 2000 (ESIGN), the U.S. Uniform Electronic Transactions Act (UETA), and the Electronic Identification Regulation (EU) 910/2014 (referred to as “eIDAS”).

Signature Authentication

How concord helps you prove exactly who signed what

One of the principal strengths of an electronic signature is its ability to precisely verify and prove the signer’s identity, compared to a handwritten signature where forgery is hard to prove.

To help you identify who is signing your documents, Concord combines the broadest range of authentication methods on the market, including: verified email addresses, IP addresses, Mac addresses, technical information from the devices used for signature, sms/email signature confirmation codes, social IDs, SSO, and other third party IDs, as well as Concord’s account IDs.

Document Integrity

How concord protects you against tampering

Unlike manually signed paper documents that can easily be modified, Concord’s electronically signed documents are virtually impossible to alter.

During and after the signature process, Concord time-stamps each document and seals it using the U.S. Federal Information Processing Standard Sha-1 Secure Hash Algorithm. This process enables you to verify your document’s integrity at anytime with the certainty that it has not been compromised.

Court-admissible Evidence

How concord assists you in court

By creating a comprehensive audit trail gathering all access instances, actions, and signatures of each participant to a document, concord provides you with all the evidence necessary to defend your documents against repudiation in court.
