What does AFIS stand for in the context of fingerprint technology?
Answer: Automated Fingerprint Identification System
AFIS stands for Automated Fingerprint Identification System, which uses algorithms to search and match fingerprint records electronically.
What is the FBI's national AFIS system called?
Answer: NGI (Next Generation Identification)
The FBI's national fingerprint system is called NGI (Next Generation Identification), which replaced the legacy IAFIS system.
What type of features does AFIS software primarily use for fingerprint matching?
Answer: Minutiae points (ridge endings and bifurcations)
AFIS primarily matches fingerprints by comparing minutiae — the locations and directions of ridge endings and bifurcations.
What is a 'candidate list' generated by AFIS?
Answer: A ranked list of potential matching records returned after a database search
After an AFIS search, a candidate list is generated ranking database records by similarity score for human examiner review.
What is the difference between a ten-print search and a latent search in AFIS?
Answer: Ten-print searches compare full rolled impressions against enrolled records; latent searches compare crime scene fragments
Ten-print searches match full enrollment records against each other, while latent searches match partial crime scene impressions against the ten-print database.
What does 'enrollment' mean in the context of an AFIS tenprint system?
Answer: Adding a new subject's tenprint record into the database for future searching
Enrollment is the process of adding a new subject's biometric data (tenprint impressions) into the AFIS database as a searchable record.
