Biometric Systems: A Comprehensive Review

Abstract

As the utilization of biometric data grows, it is expected that systems will become more dependable and capable of providing successful outcomes in challenging scenarios and in the face of counterfeiting. Ensuring the security of information is important to the effective functioning of any system. Hence, a stringent approach is necessary to authenticate the identity of each individual prior to granting them access to the stored data. Cancellable biometrics can enhance the security and privacy of users in response to potential threats. This study reviews and discusses many components of the biometric system, including face recognition, fingerprint identification, iris recognition, speaker recognition, gait recognition, ear recognition, and hand scanning. Authentication for the Biometric database is included in each section. For each segment, we will evaluate an article and analyze the discoveries presented in that paper during our review. Authentication is performed by all sections inside a filed biometric database
