UIDAI’s Iris Authentication proof of concept study successful
The UIDAI has successfully conducted the proof of concept Iris authentication study in Mysore district of Karnataka. The study brought out the high accuracy levels (above 99.2%) achieved by iris authentication. A combination of iris and fingerprint authentication can further the goals of universal inclusion and pave the way for successful applications based on Aadhaar authentication. In line with UIDAI’s successful and proven practice of conducting Proof of Concept (PoC) studies before launching any service, a PoC has been conducted to characterize & identify optimal authentication setups for online iris authentication. The PoC was conducted in semi urban setting in Nanjangud taluk in Mysore district of Karnataka between May 27th and July 30th 2012. 215,342 iris authentication transactions from 5833 residents were studied in this PoC. Eight models of iris cameras through six different OEMs participated in this study. This study has also brought out the specific improvement areas that biometric ecosystem needs to work upon to further improve the accuracy and coverage percentage. The detailed findings are documented in a report which is being published on UIDAI’s website. This will be followed by a workshop with the device vendors to guide them on the specific actions to be taken by them to improve algorithms and devices. UIDAI will then take up further field studies. These studies would also lead to formulation of iris device specifications for certification and deployment purposes. It may also be noted that as a result of feedback to the biometric ecosystem, the performance of fingerprint authentication improved substantially from the time UIDAI conducted its first fingerprint authentication PoC to the last PoC. Same is expected in iris authentication domain too, which points that iris authentication has a scope of providing accuracy levels above 99.
