Fingerprint recognition technology is a biometric technology. The fingerprint recognition system is a set of pattern recognition systems including fingerprint image acquisition, processing, feature extraction and comparison. Fingerprint recognition is often used in places that require identification of personnel such as access control systems, time and attendance systems, notebook computers, bank internal processing, and bank payments. Because of their individual differences and stability, fingerprints have been used for identity verification in ancient times. In the 1960s, with the development of computer technology, the US Federal Bureau of Investigation and the French Paris Police Department began to study computer fingerprint recognition technology.
