Abstract: Face recognition technology uses closed-circuit television to photograph a person’s face. Software then analyzes contours and bone structures and converts them into a code line that is processed through a database of known criminals and their facial codes to seek a match. Leading face recognition companies that provide this technology include Visionics Corporation, Graphco Technologies, Inc., and Imagis Technologies, Inc. Face recognition systems do not violate any constitutional rights, because no reasonable expectation of privacy exists in public places. However, the United States Supreme Court recently decided that the police must obtain a warrant before scanning a home with an infrared camera. The issue of scientific validity and reliability in court will also become a topic of a court challenge. Another issue is the ability of individuals to deceive the camera by using sunglasses, wearing hats, growing facial hair, or other techniques. Camera angles, distance, and illumination also raise questions regarding the validity and reliability of face recognition software. Signs that warn that cameras are in use, plus public meetings and information sessions, can affect the public’s perception of the technology. The technology is a simple and efficient way to increase public safety while taking crime prevention to new levels. Photographs
