Digital Signature vs Electronic Signature

An electronic signature (eSignature) is the digital equivalent of a traditional handwritten signature. They are used to validate the authenticity of documents in a digital format, being implemented through the US Federal ESIGN Act. 

eSignatures can be a digital symbol, image, or video file attached directly to an email or electronic document with the intent to sign it. In other words, this can be as simple as typing our name into a document or using a digital signature tool like DocuSign to apply a signature. These software programs can interpret our input gestures, such as a finger drawing a signature on the screen.

The electronically signed documents are signed, encrypted, and stored in a digital format in a secure, cloud-based system, making them instantly accessible.

A digital Signature is a type of electronic signature used following the ESIGN Act. It is created by applying a unique algorithm to an encrypted document using a special cryptographic code or hash. The process begins with a unique digital identifier for the paper that can only be unlocked using the corresponding public key.

The process creates a unique digital identifier for the document that can only be unlocked using the corresponding public key. This allows anyone with access to the document to verify its authenticity without having access to the private key. When the document or message is received, the digital signature is checked against the code attached to it to verify our identity. If the codes match, the paper or letter is authenticated, and our signature is recognized. 

• Electronic signatures can take multiple forms of signing documents electronically – from simply writing down with your finger on your phone to utilizing advanced cryptographic methods for secure transactions. Digital signatures are a type of electronic signatures that are used for maximum security by using cryptography algorithms. 
• Electronic signatures have three levels of security: low (simple electronic signatures), medium (advanced electronic signatures), and maximum (qualified electronic signatures). Digital signatures are only of a high level of security. 
• Electronic signatures may or may not involve authentication measures – depending on the security level. Digital signatures often use digital certificates. 
• Electronic signatures are legally recognized in many jurisdictions, especially for routine and low-risk transactions. Digital signatures have a more robust legal standing and are considered more reliable in legal contexts. 
• Digital signatures often adhere to specific standards – for example, the Public Key Infrastructure (PKI) framework.
