Signature Authenticity Definition and Examples

Understanding Signature Authenticity for e-Signing

In the world of electronic documentation, signature authenticity plays a crucial role in ensuring that agreements and contracts are both legally binding and secure. Signature authenticity refers to the assurance that the person signing the document is indeed the person they claim to be, and that the signature has not been altered or forged.

What is Signature Authenticity?

Signature authenticity is the process of verifying the genuineness of a signer's identity and the integrity of their signature in an electronic document. This validation ensures that both parties in a transaction can trust the signed document, reducing the risk of fraud and legal disputes.

How is Signature Authenticity Achieved?

  1. Identity Verification: Before signing, the e-signature platform typically uses various methods to verify the signer's identity. This can include email verification, two-factor authentication (2FA), and even asking for photo ID.

  2. Digital Certificates: Some e-signature solutions, like GoodSign, utilize digital certificates issued by trusted Certificate Authorities (CAs). These digital certificates bind the identity of the signer to a digital key, providing an additional layer of security.

  3. Audit Trails: A comprehensive audit trail records every action taken on the document—from the moment it is sent to when it is fully executed. This log includes timestamps, IP addresses, and other forensic data, making it easy to track and verify all interactions.

  4. Encryption: Encrypting the document ensures that its contents cannot be altered once signed. The encryption keys used during this process are only accessible to authorized parties.
