Fingerprint and Other Biometrics

Fingerprint and Other Biometrics – http://www.fbi.gov/about-us/cjis/fingerprints_biometrics

Representative questions that can be answered with this resource:

  • Should subjects follow along with the fingerprint collection process?
  • How often is CODIS used in criminal cases?
  • What are three features found in fingerprints?


This would be good background for spy or crime stories. Some of the items of interest:

Integrated Automated Fingerprint Identification System (IAFIS) – Describes the database and tells how long it takes to produce a hit (~30 min). Prior to it’s activation in 1998, it could take weeks or months to match a print if a match existed.

Combined DNA Index System (CODIS) – From the website, “CODIS is the acronym for the “Combined DNA Index System” and is the generic term used to describe the FBI’s program of support for criminal justice DNA databases as well as the software used to run these databases. The National DNA Index System or NDIS is considered one part of CODIS, the national level, containing the DNA profiles contributed by federal, state, and local participating forensic laboratories.”
