Read this article further to understand what Aadhaar eSign is, how it works, and what are its benefits for both individuals and businesses.

What is Aadhaar eSign?

Aadhaar eSign is an online electronic signature service that uses the Aadhaar authentication system to digitally sign documents. This solution allows individuals with a valid Aadhaar number to sign documents electronically, providing a legally binding and secure alternative to traditional handwritten signatures. 

How Does Aadhaar eSign Work?

The Aadhaar eSign process involves several steps, ensuring both security and authenticity. Here’s a step-by-step guide to understanding how it works:

1. Initiation and Consent

The eSign process starts when the user provides their Aadhaar number and gives consent to use it for electronic signature purposes. This consent is crucial as it authorizes the use of Aadhaar number for verification.

2. Authentication

The user’s identity is authenticated using the Aadhaar number. This can be done in two ways:

• Biometric Authentication: The user’s fingerprint or iris scan is matched with the biometric data stored in the Aadhaar database.
• One-Time Password (OTP) Authentication: An OTP is sent to the user’s registered mobile number with Aadhaar. The user enters this OTP to verify their identity.

3. Signing

Once authentication is successful, the Electronic Signature Service Provider (ESP) generates a digital signature. This signature is then affixed to the document, ensuring it is legally binding and secure.

4. Validation

The digitally signed document is then validated and is ready to be distributed. The signature holds the same legal validity as a traditional handwritten signature, thanks to the legal framework established by the Information Technology Act, 2000.

• ASPs (Application Service Providers): Provide the frontend services that enable users to eSign documents using Aadhaar.

Security and Privacy

Aadhaar eSign uses advanced security measures to ensure the confidentiality and integrity of digitally signed documents. These include:

• Encryption: Ensures that the data transmitted during the signing process is secure and cannot be tampered with.
• Biometric and OTP Authentication: Provides powerful identity verification, reducing the risk of unauthorized access.
• Audit Trails: Maintains a detailed record of the signing process, including timestamps, IP addresses, and user details, which can be used for future reference and verification.

How to Use Aadhaar eSign

Here’s a simplified procedure for using Aadhaar eSign:

1. Log In: The user logs into the eSign portal provided by an ASP.
2. Upload Document: The document that needs to be signed is uploaded to the portal.
3. Initiate eSign: The user then chooses for Aadhaar eSign and provides their Aadhaar number.
4. Authenticate: The user’s identity is verified using either biometric data or an OTP.
5. Sign: Upon successful authentication, the ESP generates a digital signature and affixes it to the document.
