Introduction   (5 mark question) Biometrics (refers to or metrics) related to human characteristics and traits. Biometrics identification (or Biometrics authentication) is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are used surveillance. Biometrics is the science and technology of measuring and analyzing biological data . In Information technology, biometrics refers to technologies that measure and analyze human body characteristics, such as DNA, fingerprint, eye-retina and irises, voice patterns, facial patterns and hand measurement, for authentication purposes.
