Since I recently shared some news on “Baby Steps Toward Order of Magnitude Increases in Fingerprint Resolution,” I figure I should share what Integrated Biometrics has to say on the matter.
In its article “The Science of Infant Biometrics: Are We Really There Yet?” Integrated Biometrics identifies three key components for success: capture, storage, and matching. Since the Bredemarket blog has previously discussed capture, I’ll quote a bit of what Integrated Biometrics has to say about it.
[I]nfant fingerprints have smaller ridge spacing (roughly) 4-5 pixels compared to 9-10 in adults). Movement, skin peeling, and soft, malleable skin can also distort the fingerprint, making it difficult to capture accurate data.
Because of that size, the company cites studies that suggest a capture resolution of 3500 ppi and beyond may be necessary.
But that’s not the biggest of the three key components. The biggest one is matching, because even if you capture the best infant image, it’s of no use if it doesn’t correctly match (or not match) against adult images.
Luckily, we’re now at the point where we’re starting to get data for the same person at infant and (near) adult ages, so we can study the issue. Integrated Biometrics’ post contains more detail in the section “Can Today’s Algorithms Track Biometric Evolution from Infancy to Adulthood?” I’ll direct you there to read about it.
