HYDERABAD: A detailed analysis of the biometric accuracy and performance based on 8.4 crore Aadhaar enrollments across the country has shown that the present technology being used to gather data was highly accurate.
Releasing a report titled 'The role of biometric technology in Aadhaar enrollment', the Unique Identification Authority of India (UIDAI) said on Tuesday that this analysis had put to rest the fear that the use of biometric technology in the Indian context would be unreliable and flawed
UIDAI director-general R S Sharma, in press release, said, "This certainly gives us a high degree of confidence in executing this prestigious project of national importance. It has been affirmed that UIDAI's biometric capability for enrolments is ready to handle high turnout (10 lakh Aadhaars per day), accuracy (99.965% on duplication detection) and scale (database can be of 112 crore people)."
The primary design decisions that have enabled achievement of this high degree of accuracy and scale are combining both 10 finger prints and 2 Iris has greatly improved accuracy of de-duplication. It has also contributed to lowering costs, increasing throughput and fine-tuning accuracy.
Based on the analysis, the UIDAI confirms that the enrollment system has proved to be reliable, accurate and scalable to meet the nation's need of providing unique Aadhaar numbers to the entire population. It is asserted that the system will be able to scale to handle the entire population.
The analysis resulting from such a large data set is empirically repeatable and statistically accurate.
The release quoted UIDAI chairman Nandan Nilekani as saying, "The UIDAI biometric system is processing over 100 trillion biometric person matches with a high degree of accuracy each day. This makes it not only one of the most accurate but soon to be the largest biometric system in the world."
The UIDAI has issued over 10 crore Aadhaar numbers as of December 31, 2011, since issuing the first Aadhaar number on September 29, 2010 in Tembhali in Maharashtra.
