Biometric Recognition: Challenges and Opportunities
sons of future interest and in-mission analysis to detain persons of interest from biometrically supported watch lists. These systems are considered by many to be a technical success today, and the data are shared, when appropriate, with the FBI, DHS, and the intelligence community. When first deployed they did not go through factory or system acceptance tests due to the rapid prototyping and the demand for devices. After operational use, it was determined that the fingerprints collected were not usable by the FBI because several factors had not been considered in the original tactical system design, which did not include sending output to the FBI’s strategic system, IAFIS. BAT was then formally tested operationally and the required changes identified and made. The operational retests before and after deployment showed that the current generation BAT systems generally met all of the image quality and record format protocols specified by the FBI. These BAT devices, however, use proprietary reference representations to share information on watch lists, which makes them less interoperable with standards-based systems than with one another.
