Difference Between Digital Signature and Electronic Signature: A Complete Guide

The legal effect of a particular electronic signature is determined by the applicable law, the nature of the transaction and the requirements associated with the signing method.

What Is a Digital Signature?

A digital signature is a kind of electronic signature that applies cryptography to verify the authenticity of an electronic record and to help detect any unauthorized changes to the data that has been signed.

Electronic signatures generally use asymmetric cryptography using a private key and the associated public key. The signature is created using the private key and verified with the public key. Digital signing can be built into existing document and enterprise workflows for organizations needing reliable digital signature solutions .

That is the difference between a digital signature and electronic signature. This is a cryptographic process that binds the signature to the information that is signed and enables its verification.

Difference Between Digital Signature and Electronic Signature

The difference between digital signature and electronic signature can be understood from their definition, technology, security, authentication and applications.

1. What's That?

Electronic Signature: A general term for any electronic way to show that a person agrees with the data in a document.

Digital Signature: It is a special type of electronic signature which uses cryptographic technology to confirm the identity of the signer and to ensure the integrity of electronic information.

2. Technologies Used

Electronic Signature: This can be as basic as typing a name, tracing a signature, clicking an approval button or online signing process.

Digital Signature: It uses cryptography algorithms, key pairs and verification methods to create and verify the signature.

3. Security

Electronic Signature: Security is based on the implementation of the signing platform, identity verification, authentication, control of access and audit mechanisms.

Digital Signature: It provides more technical security as the cryptographic verification can verify the authenticity of the signature and can help in detecting any modifications to the data signed.

4. Authorization

Electronic Signature: Authentication may be performed by email verification, passwords, OTPs, account authentication etc.

Digital Signature: Authentication is based on cryptographic keys and, for certificate-based implementations, on a digital certificate associated with the signer.

5. Completeness of Documentation

Electronic Signature: Whether a document can be detected as altered depends on the signing service technology and security controls.

Digital Signature: Cryptographic verification can be used to determine if the signed document has been modified after the signature was attached.

6. Digital Certificate

Electronic Signature: Not all electronic signatures require digital certificates.

Digital Signature Certificate: Electronic signatures based on certificates generally require a Digital Signature Certificate issued by the relevant certification authority.

7. Law Regime

Electronic Signature: There is no legal recognition of an electronic signature except as provided by applicable law for the requirements of the transaction and the specific method used to apply the electronic signature.

Digital Signature: India has taken a specific approach toward digital signature through the Information Technology Act, 2000 and the rules and certification infrastructure framed thereunder. The India Code contains provisions relating to standard electronic signatures, their authentication and legal recognition.

8. Easy to Use

Electronic Signature: Suitable for everyday contracts, approvals, forms and business processes.

Digital Signature: Depending on the method of certificate-based signing, there may be other technical or certificate-related requirements.

9. Typical Utilizations

Electronic Signature: Used extensively in contracts, HR documents, consent forms, customer agreements, approvals, applications and routine business paperwork.

Digital Signature: It is mostly used for government fillings, electronic tenders, regulatory process, tax-related activities, corporate compliance and transactions requiring a stronger authentication.

10. Main Objective

Electronic Signature: The primary use is to provide an electronic sign of consent, approval or intention to sign.

Digital Signature: Digital signature is used for authentication and verification of the signed electronic information using cryptographic techniques.

11. Bridging Two

Electronic Signature: This is the more generic term of electronic signing.

Digital Signature: It is a special type of electronic signature based on technology.

So, when comparing digital signature vs electronic signature, it's better to think of standard as part of the electronic signature rather than two totally different technologies.

Is Electronic Signature and Digital Signature the Same?

No, electronic signature and digital signature are not exactly the same.

Electronic signature is a general term which may include several electronic methods of signing or indicating approval. A digital signature is a type of electronic signature that uses cryptographic technology.

An easy way to remember the difference is:

Electronic signature = Wider concept

Digital signature = Cryptographic signing method

This is the reason sometimes searching for e signature vs digital signature or digital vs electronic signature may create confusion. The two terms overlap but are not interchangeable in every technical or legal context.

Legal Validity of Digital and Electronic Signatures

India has accorded legal recognition to electronic records and electronic signatures under the Information Technology Act, 2000. The Act provides for validation of electronic records and recognition of electronic signatures subject to the applicable requirements. Legal electronic signature methods allow businesses and individuals to sign a variety of digital transactions.

In India, there is a well-defined legal framework for electronic signatures, backed by the country's Public Key Infrastructure. Digital Signature Certificates are issued by Certifying Authorities who are licensed. The validity of a particular signature may depend on the type of document, transaction, method of authentication and applicable laws. So organizations should opt for the signing method according to the legal and compliance requirements of the document.

Advantages of Digital and Electronic Signatures

Organizations can move to paperless processes using either electronic or electronic signatures.

Some of the main benefits are:

Faster Papers Processing - You can sign and return documents electronically, without having to wait for them to be printed, delivered and scanned.

Less Paper Work - Digital signing minimizes reliance on physical documents and can help organizations to reduce paper-based administration processes.

Improved Workflow Management - Electronic signing can be integrated into document-management, HR, ERP automation , procurement and other business processes.

Better Accessibility - Many signing processes can be done remotely, instead of users having to be in the office.

Better Document Security - Electronic signatures can provide cryptographic verification to aid in verifying the signer and detecting change to the signed information.

Final Thoughts

As organizations are shifting from traditional paper work to digital workflows, it is important to understand the difference between digital signature and electronic signature.

An electronic signature is a generic term for any electronic indication of a person's intent, approval or consent. Digital Signature A digital signature is a specific type of electronic signature that uses cryptographic technology to verify the signer and help ensure the integrity of signed information.

The choice between a digital signature or electronic signature will be based on the transaction's purpose, security requirements, applicable laws, authentication requirements, and business workflow.

As digital transformation changes the way businesses work, knowing about digital signature and electronic signature, how they differ, what they're used for and the legal aspects involved will help organizations put in place secure and efficient document-signing processes.
