3-D Fingerprint

FIRST 3-D MODEL OF HUMAN FINGERPRINT DEVELOPED:

An Indian-American scientist has built the first 3-d model of a human fingerprint, an advance that could boost the accuracy of fingerprint-matching systems and improve security technology. Anil Jain from Michigan State University, and colleagues developed a method which takes a two-dimensional image of a fingerprint and maps it to a 3-D finger surface.
The 3-D finger surface, complete with all the ridges and valleys that make up the human fingerprint, is made using a 3-D printer. It creates what Jain’s team called a fingerprint ‘Phantom’ imaging phantoms are common in the world of medical imaging. For example, to make sure an MRI machine or a CT scanner is working properly, it needs to first image an object of known dimensions and material properties. While the 3-D model doesn’t yet have the exact texture or feel of a real finger, it could advance fingerprint sensing and matching technology
