This presentation discusses face recognition and biometrics technologies. It begins with definitions of face recognition as using facial features to identify individuals by comparing images to stored databases. Biometrics identifies individuals using unique physiological or behavioral characteristics. The presentation then discusses how these systems work through detection, recognition, and comparison stages. Examples are given of applying these technologies at universities, stadiums, banks, and other locations for security and crime prevention, though some argue it risks privacy invasion if not regulated. In conclusion, such modern technologies are useful if proper policy and oversight exist.
