Introduction to Forensic Biometric Analysis 

Biometrics is one of the most fascinating ways to solve crime. It is an automated way to establish the identity of a person on the basis of his or her physical fingerprint, face, hand/finger geometry, iris, retina, ear, etc.) and behavioral characteristics (signature, voice, gait, odor, etc.). Biometric technology makes a contribution to crime detection by associating the traces to the persons stored in the database, ranking the identity of persons, and selecting a subdivision of persons from which the trace may originate. A biometric system is a pattern recognition device that acquires physical or behavioral data from an individual, extracts a salient feature set from the data, compares this feature set against the features set stored in the database, and provides the result of the comparison.
