Fingerprint Data Acquisition: print Sensing With Embedded Technology

摘要

Identifying and matching fingerprints is a tedious process that involves huge databases. Today, a few companies are using embedded microcontrollers to create stand-alone print-sensing systems. Jeff examines the latest fingerprint security technology from Atmel. I thought the popular television show CSI: Crime Scene Investigation would have run its course by now. However, even with two spin-offs, it still isn't losing its appeal. Because I stare at a monitor all day long, I try to limit my evening's radiation intake to CSI (or an occasional episode of Myth-Busters or American Chopper). Each high-tech CSI lab (Las Vegas, Miami, and New York) uses virtual screens and some of the newest sensors for analyzing smells, sounds, chemicals, DNA, and bodies. Databanks are available for almost everything imaginable: motor vehicles, military personnel, criminals, glass, fabrics, feathers, and more. One of my favorites is the fingerprint databank-or should I say "databanks"?
