Digital Transformation
In the current landscape where business workflows and customer interactions are getting digital, organisations are also increasingly moving away from paper-based signatures. The shift to remote work cultures and hybrid business models in global collaboration signifies how the traditional handwritten signature is often no longer practical.
Such a shift requires signing technologies that are fast, secure and integrated. Electronic signing (e-signing) and digital signature technologies are the pillars of this transformation supporting everything from contract execution to onboarding, from compliance to audit-ready processes.
Global Adoption
The adoption of e-sign and digital signature technologies is expanding globally. According to Fortune Business Insights, the market is projected to grow from USD 9.85 billion in 2025 to USD 104.49 billion by 2032, with a CAGR of 40.1% during the forecast period
Many countries and regions, including the EU under its eIDAS Regulation, the US under the ESIGN Act and UETA and India under IT Act, 2000 have legal frameworks recognising electronic signatures, their legal validity and their traceability requiring organisations operating across jurisdictions need to understand both the technology and the legal/regulatory framework of digital signing.
Adaptability of e-Sign and Digital Signatures:
The adaptability of digital signatures and e-signatures cover a broad range of functions as:
- Contract execution like sales contracts, supplier agreements and NDAs
- HR workflows like employee onboarding, employee contracts, offer letters, appraisal documents
- Finance & banking workflows for loan documents, account opening, forms and more.
- Governance & compliance frameworks including tax filings and regulatory submission
As businesses expand globally and operate across time zones, remote and cross-border workflows need the ability to sign electronically not just as a convenience but a necessity making it essential to adopt a secure digital signing platform that supports global teams.
Meaning of E-Signature and Digital Signature
E-signature and Digital signature often are used interchangeably in the broader sense but when we look closer into legal and regulatory frameworks, they hold different requirements and criteria to be used in various cases.
Digital signature is a type of electronic signature.
Electronic Signature:
E Signature (Electronic Signature) is a broad term for any electronic method that signifies an intent to sign a document. As per the European Commission: an electronic signature is “data in electronic form which is attached to or logically associated with other data in electronic form, and which is used by the signatory to sign.”
Under the EU’s eIDAS framework (which serves as a benchmark globally), there are three main types of electronic signatures:
- Simple Electronic Signature (SES): Simple electronic signature is the most fundamental type of signature which requires minimal authentication or verification. This type of signature can just require the signer’s email address or a unique access code to sign the contract. Basic forms of SES are a handwritten scanned signature or simply the name of the signer.
- Advanced Electronic Signature (AES): An Advanced Electronic Signature requires additional verification and authentication and establishes a unique link between the signer and the signature. An AES mandates proof of authentication in the form of National ID of the signer or a unique access code.
- Qualified Electronic Signature (QES): A Qualified Electronic Signature (QES) is the most secure and legally binding type of electronic signature under the EU’s eIDAS Regulation. It requires rigorous identity verification, face to face or via an audio/video, from the signer and is verified through a Qualified Trust Service Provider (QTSP). QES requires only specific qualified digital signature devices such as certified hardware tokens or secure software. Each QES is backed by a qualified digital certificate to maintain authenticity, integrity, and non-repudiation in legal proceedings. Because of these safeguards, QES is ideal for regulated industries and high-value and cross-border transactions
Each type offers increasing levels of identity assurance and legal weight.
Uses of E-Signature
Electronic signatures are very widely useful across many business functions depending on the level of verification and convenience needed. Many uses include:
- HR documents like Employee onboarding forms, HR documents, internal approvals
- Contracts like Sales contracting, supplier onboarding, vendor agreements
- Day to day documents and approvals like business forms, insurance claims, rental agreements
- Other uses include remote signing, mobile signing, cross-device workflows as they are easier to implement than full PKI-based digital signatures and ideal for high volume and low risk documentation.
Digital Signature
A digital signature (DS) is a specific type of electronic signature which relies on cryptographic techniques to ensure authenticity, integrity and non-repudiation of a document. It creates a unique fingerprint (hash value) which signifies the uniqueness of each signature every time along with the signer. A digital signature uses Public Key Infrastructure (PKI) to ensure high level of security.
PKI has two public keys, a private key and a public key. A private key is unique to the signer and can only be accessed by him to sign the document while the public key is used by anyone who wants to verify the signer’s identity and to ensure the document
Uses of Digital Signature
Digital signatures are especially suited for cases when the when integrity, non-repudiation and compliance are non-negotiable or documents require the highest level of security:
- Legal contracts and regulatory filings where proof of signer identity and document integrity are of priority
- Banking and financial documents such as loan agreements, account openings
- Government and public sector processes which involve high-stakes digital documents
Key Differences Between E-signature and Digital Signature:
E-signature and Digital signature both hold different features, legal validity and security requirements as follow:
| Feature | Electronic Signature | Digital Signature |
| Definition | Umbrella term for any electronic act of signing. | A specific type of cryptographic e-signature backed by Public Key Infrastructure and certificate mechanisms. |
| Technology & Infrastructure | E-signature can be simple: a typed name, a click or a scanned image. No certificate is required in most cases. | Requires digital certificate, a unique private and public key infrastructure, hash value and encryption. |
| Security & Integrity | E-signature requires lower level of security and verification. It is generally used for everyday documentation. Good for intent. | Digital signature requires higher level of verification and authentication ensuring the document has not been altered, has strong identity verification and non-repudiation. |
| Legal / Regulatory Assurance | They are widely legally valid based on jurisdiction and may have less proof in disputes. | They are of highest assurance and in many jurisdictions are equivalent to handwritten signature (especially QES in EU). |
| Typical Use-cases | E-signatures are for high-volume and lower-risk workflows to ensure fast turnaround by remote/mobile signing. | Digital signatures are ideal for regulated industries, high-value documents and compliance-sensitive workflows. |
| Cost / Complexity | Thet often ensure lower cost, faster setup and convenience. | They often lead to higher cost and complex regulatory frameworks (certificate issuance, key management, infrastructure) |
In essence, if speed, scale and convenience are your priorities, electronic signatures are appropriate. If security, integrity, audit trail, identity assurance and compliance are your priorities, then digital signatures are the ideal fit.
In Summary
The shift from paper to digital workflows demands signing solutions that match the business needs for compliance, integrity, security and authentication. Electronic signatures provide a flexible approach to speed and convenience needed for various everyday processes. Digital signatures ensure the integrity, strength and assurance needed for high-risk transactions and regulated workflows.
Organisations should understand the need for security, legal or regulatory requirements and document value and define their signing strategy.
