This ER diagram for a face recognition system depicts the various steps taken to develop a face recognition system. Using biometrics, a facial recognition system maps facial features from a photograph or video. To find a match, it compares the information to a database of known faces. Facial recognition can aid in verifying a person's identity, but it also raises privacy concerns. Face detection enhances surveillance efforts and aids in capturing criminals and terrorists. Personal security is also improved because hackers have no passwords or other sensitive information to steal or change. This ER diagram for a face recognition system provides a thorough understanding of the system.
