Defining AFIS Latent Print 'Lights-Out'

摘要

The criminal justice communities use the science of fingerprints to perform two major operations. The first is 10-print fingerprint operations with the primary purpose of establishing an individuals fingerprint biometric identity and their respective criminal history record. The second is forensic latent print examinations with the primary purpose of supporting criminal investigations in an effort to solve crimes. Both operations are crucial in supporting subsequent legal proceedings. This paper introduces and explores an incremental approach to automating more of the forensic latent print examination process. Since the 1960s National Institute of Standards and Technology (NIST), Information Technology Laboratory (ITL) has been instrumental in Automated Fingerprint Identification Systems (AFIS) 10-print fingerprint research and development. These efforts culminated with the establishment of the first fingerprint interchange standard in 1986 and the continuous updating of the standard. The latest draft revision to the standard is the ANSI/NIST-ITL 1-2011, Data Format for the Interchange of Fingerprint, Facial, and Other Biometric Information. In 2006 NIST ITL initiated the Evaluation of Latent Fingerprint Technology (ELFT) program; a prime objective of ELFT is to test AFIS technology accuracy when searching and matching crime scene latent prints against large 10-print fingerprint repositories.
