Digital signatures existed in India for more than two decades. For a prolonged period, they were limited to USB token-based e-signatures, better known as DSC or Digital Signature Certificate Tokens. While these tokens were technologically innovative, they had concerns with their availability, portability, and incompatibility with mobile devices. Esign Aadhaar addresses all the challenges that digital signature certificate tokens had and has now become a government-prescribed method of signing a document digitally. In this article, we give you a comprehensive look at what Aadhaar-based Esign is, how to validate the signature in Aadhaar card and more.
What is an ESign Aadhaar?
The Aadhaar card is one of the prominent identification systems in the country. It is trusted by millions and includes every registered resident’s demographic and biometric data. Esign Aadhaar is a government-authorized way of digitally signing a document. It is an electronic signature that is unique and is based on a person’s Aadhaar data. The advent of Esign Aadhaar was to alleviate all the problems associated with digital signatures in the country. As an encrypted signature, Esign Aadhaar can be effectively leveraged to sign digital documents like agreements, contracts, and letters.
