Aadhaar de-duplication myth busted. Any answers, Mr Nilekani?

One person from Kerala enrolled and successfully received two Aadhaar numbers. This raises serious question over the de-duplication theory and practices of UIDAI

Aadhaar or the unique identification (UID) number is being enforced by the governments and the de-facto tagging institution, the Unique Identification Authority of India (UIDAI) by claiming uniqueness of the number. However, one person from Kerala has busted the myth created by UIDAI and its chairman Nandan Nilekani.


According to a report in Matrubhoomi, a Kerala-based newspaper, PV Narayanan, a resident of Panatthadi panchayat received two Aadhaar numbers: 548780623023 and 356459270677. The names on both these letters issued by UIDAI are same, with slight different photos. Narayanan probably may have registered at two places or centres. But, surprisingly, his fingerprints seem to have passed the so-called ‘robust’ de-duplication test of UIDAI. Since Aadhaar includes an iris scan, this too seems to have been missed.


As Moneylife has pointed out, both the union government and UIDAI were in such a hurry that they neglected the basic principle of pilot testing and size of sample. For over 1.2 billion UID numbers, they have used data from just 20,000 people, in pairs, as the sample and on the basis of the results, gone ahead with the UID number through the 'Aadhaar' project. (How UIDAI goofed up pilot test results to press forward with UID scheme)


The case of Narayanan also mocks the false positive identification rate (FIPR) theory of UIDAI. Earlier, speaking about the FIPR, the UIDAI had said, "We will look at the point where the FPIR (i.e. the possibility that a person is mistaken to be a different person) is 0.0025%". This means, for every 1 lakh comparisons, there would be two and a half false positives. On a large scale, it means for a population of over 120 crore, there would be 18 lakh crore false positives, or, for every single Indian resident there would be 15,000 false positives! (Click to see the calculations)


The International Biometric Group (IBG) testing also shows that performance can vary drastically within technologies-some fingerprint solutions, for example, had next to no errors during testing, while others rejected nearly 1/3rd of enrolled users. "Most interestingly, the testing shows that over time, many biometric systems are prone to incorrectly rejecting a substantial percentage of users. Verifying a user immediately after enrolment is not highly challenging to biometric systems. However, after six weeks, testing shows that some systems' error rates increase ten-fold," said the research, consulting and integration firm, which works closely with the biometric industry. The report is titled "Real-World Performance Testing".


Maybe the UIDAI and its registrar have thought the second enrolment of Narayanan from Kerala as false positive and issued another Aadhaar number. Hope the UIDAI chairman would be able to find out ‘original and true’ Narayayan from these two biometric-based Aadhaar numbers!

Aadhar card is a sad joke. Tomorrow, they will match your fingerprints and iris scan with any terrorist and do an Ishrat Jahan on you. You can call me a conspiracy theorist, but there's ample proof now, that Aadhar is duplicable. Maybe the government uses the database of fake Aadhars to launder or embezzle money. If hundreds of Kalavatis can be Sahara investors, then why not hundreds of me or you? Will the real one please raise his or her hand?

My family members enrolled AADHAR two years back. One member has not received the original Card although it was generated and could be downloaded online. Email sent to AADHAR was not replied and probably not read. Where is the accountability?

Recently, after obtaining Aadhaar number and taking the print-out of their electronic output, I approached my bank (a leading private bank) where I was told to come back with the original card issued by Aadhaar authorities. I do not know honestly whether I would get it from them nor is there any communication to that effect and even if so, when. So, if the numbers cannot be linked and the original is needed, it means the very beginning goes to the age-old concepts.. so, in my opinion it is a total failure!!! I think PAN card is far better an identification.

Hi moneylife, pls rewrite this article with due verification.The comments creates a confusion on the Moneylife's stand towards UID.

We want an unbiased and authentic view.
