How to validate Aadhaar card Signature?

Aadhaar card Signature?

It is an encrypted signature that may be used to digitally sign letters, agreements, and other types of documents. It is equivalent to a handwritten signature in value. Electronic signatures are distinct from digital signatures. Digital signatures are embedded cryptographically in the digital document, unlike electronic signatures, which often require typing the name in the electronic document. An electronic signature can be a customer’s scanned image of their signature, their voice, a stylus, or their initials typed into a computer. It is a digital trademark. This specific service is being used in India to enable Aadhaar card holders to electronically sign documents. An individual’s Aadhaar data is used to create a special electronic signature known as the Aadhaar Card signature.

What is e-Sign Service?

The widespread usage of ICT devices and the availability of a variety of ICT services to users necessitate the need for legitimate papers and records online. The current procedures for obtaining e-signed documents are cumbersome. The Indian government has introduced a procedure that enables CAs (Certifying Authorities) to offer e-signing services to Indian people who possess authentic Aadhaar IDs. Citizens will be able to upload the documents for e-signing as long as they have a valid Aadhaar card on them. The Aadhaar service is used to do user validation on the backend. The user is given a private key and a public key, and the signing is complete. The digitally signed document and the digital signature certificate are delivered to the user.

Benefits Of The E-Sign Service:

The widespread usage of ICT devices and the availability of a variety of ICT services to users necessitate the need for legitimate papers and records online. The current procedures for obtaining e-signed documents are cumbersome. 

Convenience:

By removing the requirement for physical presence to register an Aadhaar card signature, the e-Signature feature has made the registration process hassle-free, rapid, and real-time for customers. It also eliminates human errors and delays that are an inevitable part of the manual procedure. Hardware tokens, a crucial component of the procedure, are no longer used with the Aadhaar card e-signature.

Flexibility:

Depending on the device the service provider is using, there are various ways to register for an Aadhaar e-Signature. One is the iris and fingerprint verification process used in biometric authentication. The second method uses a One Time Password on a mobile device (OTP). In this case, an OTP is sent to the Aadhaar cardholder’s registered contact number as part of the verification procedure.

Privacy:

Service providers cannot access all information since only particular information is used in the process. Service providers are accountable for protecting the privacy of the signatory’s information.

The e-Sign project makes sure that users can digitally sign papers online using their registered mobile phone numbers and Aadhaar IDs. CA provides the applicant with a digital certificate via the e-Sign service for single signing usage. The certificate belongs to the “Aadhaar e-KYC OTP” class. For the Aadhaar e-KYC service and e-authentication, the Certifying Authority uses the UIDAI (Unique Identification Authority of India) service. e-Sign services are provided, and CA (Certifying Authority) functions are performed under CCA (Controller of Certifying Authorities).

A qualifying company was appointed to serve as an e-sign service provider by the controller of Certifying Authorities. The following list includes the authorized vendors providing e-sign services in India:

  • C-DAC
  • eMudhra Limited
  • (n)Code Solutions
