As India moves toward digitisation at an accelerated pace, electronic signatures, particularly Aadhaar-linked digital signatures, have emerged as a key enabler of seamless and secure online transactions. Aadhaar-based eSign solutions are transforming how individuals and businesses sign documents, streamlining workflows, enhancing security, and significantly reducing the need for physical paperwork. In this article, we’ll explore what an Aadhaar-based eSign is, how it works, and the substantial benefits it offers for both businesses and individuals in India’s evolving digital landscape.

What is Aadhaar-based eSign?

An Aadhaar-based digital signature (also known as Aadhaar eSign) allows users to sign documents electronically using their unique Aadhaar identity. This form of eSign is authorised under the Information Technology Act, 2000, and is legally valid, making it an accepted method for digital transactions across sectors in India.

Unlike traditional digital signatures that require hardware tokens or certificates, eSign using Aadhaar leverages the Aadhaar database for authentication, allowing users to sign documents quickly and securely from anywhere. Aadhaar eSign online solutions are designed to streamline processes like signing contracts, bank forms, government documents, and invoices with minimal effort.

How does Aadhaar-based digital signature work?

The process of using an Aadhaar-based digital signature is simple and user-friendly. Here’s how it works:

Authentication via Aadhaar.

To initiate the signing process, the user is asked to provide their Aadhaar number or a Virtual ID (VID) for identity verification.

OTP verification.

A One-Time Password (OTP) is sent to the user’s registered mobile number linked to the Aadhaar. This step ensures that the eSign process is secure and verified in real time.

Digital signature generation.

Once the OTP is entered and authenticated, the Aadhaar-linked eSign is applied to the document, ensuring that it is digitally signed using Aadhaar and legally recognised.

Document integrity.

The signed document is encrypted to maintain integrity, ensuring that any tampering or modification can be detected.

The evolution of digital signing in India: From physical signatures to Aadhaar eSign.

Before the introduction of Aadhaar eSign, signing documents required either physical signatures or using hardware-based digital signature certificates (DSCs) stored on USB tokens. This process was often cumbersome, involving in-person verification and secure key management.

The growing demand for faster, remote digital transactions prompted the need for a simpler solution. With the advent of Aadhaar-based digital signatures, individuals can now remotely authenticate their identity and sign documents using their Aadhaar digital ID. This shift has made digital signing accessible, secure, and compliant, eliminating the need for physical tokens or face-to-face verification.
