Biological changes may put UID out of bounds for kids

Children up to 15 years do not have sharp patterns of fingerprints, the metric used to uniquely identify each one of them and more importantly, for authentication. The iris — the coloured portion of the eye — that is to be used to issue a unique identity number, too, does not fully develop before seven years.

“The iris starts achieving 90% stability in size only after six years of age. A normal iris starts assuming stability only by eight years,” said Dr Rakesh Gupta, consultant eye surgeon at Max Balaji Hospital in New Delhi.

Fingerprint patterns assume stability at an even later stage, around 16 years, said Dr V Khanna, a South Delhi-based skin specialist. “Fingerprints are very feeble in children and difficult to capture,” he said.
A few posts here have dealt with the use of biometric identifiers for children.


From ghost workers (yesterday's post) to "fake babies"...
A case in point is the Janani Suraksha Yojana, which hands out incentives to mothers. Earlier this week, a fake babies scam was unearthed in Bihar where 300 women claimed to have delivered up to five babies in a span of 60 days to avail an incentive of Rs 1,000 for each baby.
India, in building a comprehensive biometric identity management system in the world's second-most-populated country, is attempting something that has never been attempted before. It is the identity management moon-shot. It is worth keeping an eye on.
