To understand the role of authentication it is important to first understand the basics of the authentication process.

  1. Aadhaar Authentication: This is the process wherein the Aadhaar number as well as the demographic, biometrics and OTP are submitted to the UIDAI’s CIDR for verification. CIDR stands for Central Identities Data Repository. Once the attributes are in the hands of CIDR, it takes it from there. The verification process involves checking whether the data which has been submitted matches the data available in CIDR. Depending on the result it responds with a Yes or a No and does not provide with any personal identity information.
  2. Benefits of Aadhaar Authentication: The benefits of the authentication are to build a healthy relationship between the residents and the service providers. It’s for the residents to be able to claim to the service providers as a proof of their identity and in return, the service providers can provide them with benefits and services.

UIDAI was basically started to provide the people a unique identification that “you live in India and that you are a citizen of India”. The Chairman Shri Nandan Nilekani speaks about the strategic value about this authentication.

He says that the authentication of Identity is done at every point and basically done in 03 ways:

  • What you know Authentication

For Example, You know the password or the pin number when using your email

  • What you have Authentication

For example: When you swipe your ATM card to withdraw money and the bank accepts that it is “your” debit card and therefore allowing you to withdraw the money. The OTP works in the same way while downloading e-Aadhaar card. The only difference is it authenticates your mobile number.

  • Who you are Authentication

For example Initially the system was started with finger prints and now an advanced biometric system called “IRIS” is used.

These authentication methods that have been introduced are very strategic in nature as they contribute majorly in reducing adoption, time and most importantly cost. He also says that UIDAIis able to reach the maximum public with minimum cost and no distribution of tokens.
