Computerized fingerprint matching 99 percent accurate
Edited for brevity.Computerized systems that automatically match fingerprints have become so sophisticated that the best of them are accurate more than 99 percent of the time, according to the most comprehensive known study of the systems ever conducted. Computer scientists at the Commerce Department's National Institute of Standards and Technology (NIST) tested 34 commercially available systems provided by 18 companies from around the world. NIST conducted the study to fulfill requirements of the USA PATRIOT Act and the Enhanced Border Security and Visa Entry Reform Act. A total of 48,105 sets of fingerprints from 25,309 people, with a total of 393,370 distinct fingerprint images, were used to enable thorough testing. The best system was accurate 98.6 percent of the time on single-finger tests, 99.6 percent of the time on two-finger tests, and 99.9 percent of the time for tests involving four or more fingers. These accuracies were obtained for a false positive rate of 0.01 percent. Posted by: Dar 2004-07-16 |
