Comprehensive Review on Different Types of Biometrics and the Impact of Pandemic on Biometric Security

With the rapid rise of electronic crimes and their related difficulties, implementing a trustworthy user authentication system has become a critical responsibility for access control and data security. Because of this, the influence of biometrics in information security has become very popular. Everybody in this world has distinct physiological and behavioural features that set us apart from others. These unique features (or IDs) are used in biometrics to determine and authenticate people's identities. This research includes comparisons between two major categories of biometrics, namely physiological and behavioural biometrics, that include finger prints, varied iris patterns, blood vessels, eye retina, vocal inflections in speech, signatures, key strokes, walking, and hand shape and geometry, all of which are unique identifiers. This research also includes the impact of COVID-19 on biometric security.
