Technological evaluation of two AFIS systems
Marcos Faundez-Zanuy
TL;DR
This paper compares two AFIS fingerprint identification systems used by Spanish police, evaluating their technological capabilities and performance, and finds that the NEC system outperforms the Printrak system in experimental tests.
Contribution
It provides a comparative technological evaluation of two real-world AFIS systems, highlighting performance differences in forensic fingerprint identification.
Findings
NEC AFIS 21 SAID NT-LEXS outperforms Printrak AFIS 2000 in experiments.
Both systems support inkless fingerprint management.
The NEC system handles larger databases effectively.
Abstract
This paper provides a technological evaluation of two Automatic Fingerprint Identification Systems (AFIS) used in forensic applications. Both of them are installed and working in Spanish police premises. The first one is a Printrak AFIS 2000 system with a database of more than 450,000 fingerprints, while the second one 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
