Overlooking the UIDAI Process

A response to the rebuttal by Hans Mathews and Pranesh Prakash to UIDAI's "Erring on Aadhaar" (EPW, 12 March 2016)

The author has used linear extrapolation to project that 1/145 enrolments could result in false positive identification because of biometric de-duplication. There is sufficient evidence from biometric literature, as cited in our earlier rebuttal (EPW, March 12, 2016), to show that extrapolation using a single data point can lead to erroneous conclusions. This is especially true for a multi-modal biometric system such as Aadhaar. Most importantly, it has been admitted by the author that operational resolution of false positives is not of interest to him.

The operation resolution of UIDAI process ensures that no person is denied of Aadhaar on account of false positives. Since the author chooses to not look at the operational resolutions, he cannot justify the title of his paper “Flaws in UIDAI process”, since operational resolution is a part of the UIDAI process.
