Dismissing fears that the biometric technology being employed for the Aadhaar project is flawed, UIDAI, headed by Nandan Nilekani, on Monday asserted that the unique ID system is accurate and reliable and can achieve the task of providing Aadhaar number to the entire population.

"Based on the analysis, the UIDAI confirms that the enrolment system has proven to be reliable, accurate and scalable to meet the nation's need of providing unique Aadhaar numbers to the entire population," the Unique Identification Authority of India (UIDAI) said.

"The UIDAI biometric system is processing over 100 trillion biometric person matches with a high degree of accuracy each day, capable of issuing 10 lakh Aadhaars daily. This makes it not only one of the most accurate, but soon to be the largest biometric system in the world," UIDAI Chairman Nandan Nilekani said in a statement here. He also released a report titled, 'The Role of Biometric technology in Aadhaar Enrolment' here on Monday.

According to the UIDAI study, it has been affirmed that the authority's biometric enrolment system is ready to handle high throughput of up to 10 lakh registrations per day and has 99.965 per cent accuracy in terms of duplication detection. The system meets the country's requirements in terms of scale as well, with the database capable of accommodating 1.2 billion people.
