ADHAR: Defines your identity

What is Aadhaar? 

Aadhaar is unique 12-digit number that will be issued to individuals by the UIDAI. The aim is to issue a unique ID number that can be verified and authenticated in an online, cost-effective manner. Most importantly, it should be robust enough to eliminate duplicate and fake identities.

However, getting an Aadhaar number is not mandatory. There is no deadline to get an Aadhaar number. Also, Aadhaar cannot be used as a replacement for existing ID proofs. It is also important to recognize that a ration card is not merely a proof of identity or address; it establishes eligibility to receive rations. Similarly, a driving license establishes eligibility to drive. Service providers may choose to embed Aadhaar into exiting forms of identification to make checks more robust.

Features of Aadhaar

You may wonder why anyone would enroll for Aadhaar if it isn’t mandatory, but having an Aadhaar number may actually be beneficial. Firstly, the number will, over time, form the basic, universal identity infrastructure over which registrars and agencies across the country can build their identity-based applications for delivery of services in an effective and cost-efficient manner. Registrars may include state governments, state public sector units (PSUs), banks, telecom companies, etc. who may in turn partner with enrolling agencies to enroll citizens into Aadhaar. Once residents enroll for Aadhaar, service providers will no longer face the problem of performing repeated Know Your Customer (KYC) checks before providing services. They would no longer have to deny services to residents without identification documents.

Another feature of Aadhaar is that, over time, it will be recognized and accepted across the country and across all service providers. Also, authentication would not be a hindrance, owing to the centralized technology infrastructure of the UIDAI. It enables 'anytime, anywhere, anyhow' authentication, which can be done both online as well as offline. Offline authentication can be done via cell phone or land line. Aadhaar will thus give migrants mobility of identity, and it will provide flexibility to poor and rural residents. It will empower them to access services like banking, public distribution system, as well as government schemes like National Rural Employment Guarantee Act (NREGA) etc.

Aadhaar will also pave the way for a more cleaner and robust data bank. Today, there are multiple databases in existence and so it’s possible for people to furnish different details to different agencies. But since Aadhaar will be centralized, the instances of duplication and fraud will be rare. Every new applicant’s data will be sent to the Central ID Data Repository (CIDR), where it will be checked and verified on key demographic fields and biometrics, against the existing data collected. This self-cleaning mechanism will ensure that there is no duplication of data.

How to get Aadhaar?

Information about the Aadhaar enrolment will be made available in the local media. You will then have to go to the enrolment camp nearest to you and register yourself for Aadhaar. At the time of enrollment, you will have to provide certain documents such as ration card, passport, voter ID, driving license, electricity bill etc. as proof of identity. After registering, you will go through biometric scanning of fingertips and iris. You will also be photographed and given an enrolment number. Your Aadhaar number will be issued to you within sixty to ninety days.

Technology Used

Your biometric profiling will be done with the help of an iris scanner, a fingerprint scanner and a Web camera. The iris cameras conduct a mathematical analysis of the random patterns that are visible within the iris of an eye from some distance. Unlike fingerprints, which can become difficult to recognize over the years due to manual labor, the iris of an eye remains unchanged and is unique to every individual. The digital photo of the iris pattern is converted into an encrypted digital template, which cannot be re-engineered or reproduced in any sort of visual image. Iris recognition therefore affords the highest level of defense against identity theft, the most rapidly growing crime. Next up is face detection, which is used in biometrics, often as a part of (or together with) a facial recognition system. It is also used in video surveillance, human computer interfaces and image database management. The face detection system will measure and analyze the overall structure, shape and proportions of the face. These include the distance between the eyes, shape of the nose, jaw structure, forehead, mouth, etc. Finally, fingerprint scanning is done with the help of a scanner that captures a digital image of the fingerprint pattern. The scan is then digitally processed to create a biometric template, which is stored and used for matching.

Once the data has been captured, it is then encrypted and sent to the CIDR (Central ID Data Repository). Here, it will be cross-checked for duplication against the existing data, thus reducing the possibilities of fraud. The authentication is enabled in a manner that the identity verification queries will only receive a Yes and No responses. Thus, the architecture ensures complete data security and under no circumstance will the residents data be shared with third parties. Also, to ensure seamless functioning, an Analytics and Continuous Improvement team reviews operations on an ongoing basis and releases relevant, actionable reports for all stakeholders.
