These databases do things that humans wouldn’t be able to do or wouldn’t have the time to do. Two specific types of databases are AFIS and Iris scan. AFIS (also known as IAFIS) stands for Automated Fingerprint Identification System. AFIS is just that‚ a database created to keep track of fingerprints. Iris scan is the scanning of the iris as a method to identify people based on unique patterns within the ring-shaped region surrounding the pupil of the eye. Even though we use technology every day
