Scientists 'unwarp' distorted fingerprints in seconds

It's long been held that no two fingerprints are exactly alike, rendering the old-fashioned print more reliable than current DNA sampling, which has resulted in false positive identifications.

But what if a fingerprint is warped? When I volunteered to be a mentor recently, I had to get my prints taken, and the process was tedious and full of re-dos because, as I rotated each finger, I tended to slightly smudge the results.

Now, the biggest problem with fingerprints--that a good one is hard to find--may have finally been solved, according to new research out of the University of Warwick in the UK. Most fingerprint techniques identify a handful of features on a print and match the entire set of characteristics against each fingerprint in a database of templates--a laborious, often time-consuming endeavor. Researchers at the University of Warwick took a different approach.
