Technological evaluation of two AFIS systems

This paper provides a technological evaluation of two Automatic Fingerprint Identification systems (AFIS) used in forensic applications. both are installed and working in Spanish police premises. The first is a Printrak AFIS 2000 system with a database of more than 450,000 fingerprints, while the second is a NEC AFIS 21 SAID NT-LEXS Release 2.4.4 with a database of more than 15 million fingerprints. Our Experiments reveal that, although both systems can manage inkless fingerprints, the latest one offers better experimental results.
