Aadhaar is a 12-digit unique number issued by the Unique Identification Authority of India (UIDAI) by taking a person’s biometric details such as iris scan and fingerprints, and demographic information like date of birth and address. Aadhaar is a proof of residence and not a proof of citizenship. It does not itself grant any rights to domicile in India. Aadhaar is the world’s largest biometric ID system, with over 1.19 billion enrolled members as of 30 Nov 2017. As of this date, over 99% of Indians aged 18 and above had been enrolled in Aadhaar. World Bank Chief Economist Paul Romer described Aadhaar as “the most sophisticated ID programme in the world”. (Source: Wikipedia & ET)
The government is trying its best to make biometric data safe and secure. The way the government is forcing Indians to link Aadhar to all financial accounts can make it robust like SSN of the USA in the future. Congress party and corrupt groups are protesting against Aadhar citing privacy as a concern, but the real reasons for the protest can be found in these two images.
