Thumbs up.

This article provides information on a technology developed by Redwood City, California-based DigitalPersona to accurately scan fingerprints for product security, as of June 2005. Vance Bjorn, chief technology officer at DigitalPersona, said it is one of those technologies that straddles security and convenience. He added that typically, there are 50 to 70 minutia points on a fingerprint. The challenge of fingerprint recognition is cutting through the static. There is a lot of variation in the real world, scars and cuts, different finger placements, and others. But the underlying signal of the fingerprint is so strong, because there is so much information unique to it, that even if some of the features are occluded, we can still reconstruct and define the features.
