Lab 7. Biometrics: Livescan and AFIS

Biometrics (from the root words bio meaning “life” and metric meaning “measure”) refers to using biological measurements for identification purposes. A historical example of biometrics is anthropometry, in which measurements of specific parts of the body were used for criminal records, classification, and identification. There are several examples of forensic biometrics that rely on the unique characteristics of individuals for identification. Forensic odontologists (forensic dentists) analyze the unique features, shapes, placement, and dental work for teeth. Facial recognition analysis involves an examination of the unique measurements, proportions, and features of the face and skin. Iris scans capture the unique patterns within the pigmented section of the eye. The forensic sciences rely on these and other biometrics to identify individuals involved in crimes.
