India's Aadhaar, with biometrics of 1B people, ignites privacy debates

This is not a problem just for Aadhaar but also for any enterprise.

Data has multiple challenges in quality - consistency, completeness, accuracy, precision, missing and unknowns, validity, timeliness, right linkages, conformity and reasonableness.

Once you have overcome those challenges, you will have ensure security, audit, management.

The problem with Aadhaar and anything that happens in India on such a huge scale (e.g. Demonetization) is that while a number of genuine people benefit from the programs, the side effects cannot be ignored - significant percentage of people suffer (sometimes immensely) and other times non-genuine people take advantage.

The solution for any such programs are for all data challenges, there should be a strategy led with right investments and executive support.

Politicians are mostly blamed for not doing enough and now a days blamed even more for doing things wrong. I think the intent of the Aadhaar program is right however there is more to be done by the Indian government on ensuring money support is given to the program to solve these problems.
