Abstract
AbstractAccess control system is a system to control the forbidden passage, which involves many fields such as electronics, machinery, communication and so on. Its structure is not complex, but it has strong practicability and great market demand. Many scholars have improved and studied the door access control system, and the application of biometric recognition to the access control system is the main research direction at present. Biometric access control system is based on fingerprint, face, iris, voice, vein and other human biometrics for identity recognition and authentication. Compared with the traditional access control system, the access control system based on biometrics has better security, convenience and functionality. At present, there are three recognition methods used most in access control system: fingerprint recognition, face recognition and iris recognition. Based on a large number of documents, this paper summarizes the main research contents, development status and research results of various recognition methods. The advantages and disadvantages of various technologies at present are pointed out, and the future development trend is prospected.KeywordsSafety lockFingerprintFace recognitionIris recognition
