Understanding Biometric Technologies: The Foundation of Modern Identification

Biometryc requions to automate requation of individuals based on behavoural and d biological characterics. Unlike traditional identification method that rely on what you know (passwords) or whant you have (ID cards), biometric systems identify individuals based oun who they ary are - using inderent physional or behavoral trait that are unique to each person.

Comon biometric traits included fingerprints, palm prints, hand vasculature, hand shape, face, DNA, iris, retina, ear shape, teeth, and sclera patterns. These physical criterics are determinad by genetics andd developmental factors, making them extremely difficult to forge or replicate.

Fingerprints remaid one of thee most widely used biometryc identifiers in foursic science. The unique ridge patterns, loops, whorls, whorls, and arches on fingertips have been use for identification destives for over a century. The iris has 266 unique spots, compard to comed tor biometrycs which have 16 to 20 distrificationt specifications.
