Tracking Tiny Fingers

To meet infant needs

Fingerprints are one of many forms of biometrics used to verify individual identify. Infant fingerprints have attracted scientists as far back in time as 1899, when Galton first captured the ink-on-paper fingerprints of a single child from birth to four and a half years of age. His study resolved the issue of the impact of growth on infant fingerprints.

Recently, researchers from the Saran Ashram Hospital, UP, in collaboration with the Michigan State University, USA, reported that fingerprints from a child as young as 6 hours old exhibit the features necessary for identification.

The team collected fingerprints from 306 children from 0 to 5 years of age, repeatedly in four different sessions, each year. The analysis of the data showed that fingerprint technology has high identity recognition accuracy for children older than 6 months.

The results might prove to be useful for child identification, vaccination tracking, improving child nutrition, and other national programs.
