What Is eSign?

What is eSign? This question has become increasingly relevant as digital tools continue to transform how we interact, transact, and communicate.

Whether in business, government, or everyday personal use, it plays a crucial role in streamlining paperless processes and enhancing efficiency.

In this article, we’ll explore its growing importance, the factors driving adoption, and what makes it a vital part of the digital landscape.

What is eSign?

eSign, short for electronic signature, is a secure method for validating and approving documents using encryption technologies and identity verification protocols.

Rather than relying on handwritten input, this system leverages tools such as public key infrastructure (PKI), certificates, and tamper-evident audit trails to confirm the origin and integrity of a file.

Various jurisdictions classify online signatures into distinct levels—basic, advanced, and qualified—each offering a different degree of legal weight and technical assurance.

Globally recognized frameworks like the ESIGN Act in the United States, eIDAS in the European Union, and India’s Information Technology Act provide the judicial foundation for their use.

Types of eSign

How does eSign work?

The eSign process follows a secure digital sequence to verify identity, protect document lawfulness, and ensure legal compliance. Here’s an overview of how to sign a document electronically:

1. Document Upload
   • The initiator browsers a file to a online signature platform.
   • Endorsers are assigned, and necessary fields (such as mark or date) are placed.
2. User Confirmation
   • Recipients verify their profile via:
     • Email
     • SMS
     • MFA
   • Access is granted only after validation.
3. Signature Capture
   • The obligor reviews the material and electronically sign PDF by:
     • Typing their name
     • Drawing initials
     • Using a certification-based essence
4. Document Protection
   • A cryptographic hash is created to uniquely represent the file’s contents.
   • An immutable audit trail records:
     • Date and time of actions
     • IP address
     • Device and location details
5. Enhanced Security (When Applicable)
   • Some systems incorporate digital signature licenses issued by trusted Certificate Authorities (CAs).
   • These link the author’s representation with the approval via public key infrastructure (PKI).
6. Finalization
   • After all affiliates complete their part, the material is sealed to prevent changes.
   • A comprehensive log is produced for future reference and regulatory adherence.

eSign the document: legal considerations

Adopting electronic signatures involves more than technology—it requires careful attention to the legitimate framework that ensures your agreements remain valid and enforceable.

1. Compliance with Regional Regulations

Each country establishes its own rules and standards to digitally sign PDF:

• In the United States, the ESIGN Act and UETA focus on witness intent, agreement to electronic dealings, and proper record-keeping.
• The European Union’s eIDAS Regulation offers equivalence to handwritten counterparts and wet signatures when issued by authorized trust providers.

2. Demonstrating Consent

Valid eSignatures hinge on proving the deliberate approval and willingness to engage digitally. Strengthen this by:

• Including clear endorsement prompts.
• Requiring affirmative confirmation through actions such as ticking checkboxes or entering security codes.
• Keeping detailed audit records that document each step of the process.

3. Verifying Identity

Confirming the authenticity of the PDF signature is crucial:

• For low-risk contracts, basic methods like email or SMS codes may suffice.
• Higher-stakes transactions demand multi-factor authentication, incorporating biometrics, passwords, or hardware tokens.
• The highest assurance involves PKI-based digital certificates, cryptographically linking signer and document.
• Regulated industries may need to integrate KYC protocols to satisfy compliance demands.

4. Safeguarding Credibility

Ensuring the unchanged state of a file is vital:

• Employ hash functions that generate a unique digital fingerprint.
• Use electronic signatures to bind status and content securely.
• Maintain thorough logs capturing timestamps, IPs, and device info.
• Implement tamper-proof measures to signal any modifications.

5. Retention and Accessibility

Long-term reliability and availability of records require:

• Storing files in stable, industry-standard formats like PDF/A.
• Utilizing encrypted, redundant storage to prevent loss.
• Preserving all metadata and audit trails.
• Adhering to sector-specific mandates concerning data privacy.

6. Recognizing Limitations

Not all documents are eligible to add signature to PDF:

• Wills and other testamentary papers.
• Certain property transfer files.
• Filings and some court orders.
• Family law instruments (subject to local rules).

Consultation with legal advisors is essential before proceeding.
