New Delhi, Apr 1: Cabinet Secretary KM Chandrasekhar has opposed the use of iris recognition (IR) test as a part of Unique Identification Database (UID) project.
Claiming the test has a useless expenditure, Chandrasekhar also requested Prime Minister Manmohan Singh to omit it as the third tool for the UID project.
Chandrasekhar said, "It is an unnecessary recurring expenditure, which will have to be paid to an American company."
Unique Identification Authority of India (UIDAI) Chairman, Nandan Nilekani had proposed to bring in high tech tools for the recognition process.
According to reports, Nilekani had suggested IR test beside fingerprinting and face recognition as biometric identification.
The IR uses pattern recognition to create images of the iris of an individual.
Even DoT and the Department of Expenditure had claimed that the face and fingerprint recognition would be sufficient for identification.
