Digital signatures comply with the most demanding regulatory requirements, including the United States Federal ESIGN Act and other applicable international laws. Other, less secure e-signature types may use common electronic authentication methods to verify the signer’s identity, such as an email address, a corporate username/ID, or a phone number/PIN.Īs a result of different technical and security requirements, electronic signatures vary in industry, geographic, and legal acceptance. Digital signatures use PKI certificates from a Certificate Authority (CA), a type of Trust Service Provider, to ensure identity authentication and document integrity by encrypted binding of the signature to the document. But there are many different types of electronic signatures, each allowing users to sign documents digitally and offering some degree of identity authentication.ĭigital signatures are one of those electronic signature technologies and are the most secure type available. As documents and communication are increasingly paperless, businesses and consumers worldwide have embraced the speed and convenience of these types of signatures. Digital Signature vs Electronic SignatureĮlectronic signatures, commonly referred to as e-signatures, are a broad set of solutions that use an electronic process for accepting a document or transaction with a signature.
Based on the highest standard of security, digital signatures are legally binding in the United States and many other countries. Digital signatures are similar to physical signatures in the sense that both are unique to the signer, except that in the case of digitally signed documents, a digital signature offers far more security and the assurance of the document’s origin, identity, and integrity. A digital signature is a PKI-based digital certificate that authenticates the identity of the signer and ensures electronically transmitted documents and digital messages have not been forged or tampered with.
