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.


A biometrics system can be either an "identification" system or a "verification" (authentication) system, which are defined below -

  • Identification - One to Many : Biometrics can be used to determine a person's identity even without his knowledge or consent. For eg :- Scanning a crowd with a camera and using face recognition technology, one can determine matches against a known database.
  • Verification - One to One : Biometrics can also be used to verify a person's identity. For eg :- One can grant physical scans or can grant access to a bank account at an ATM by using retinal scan.

The Block diagram illustrates the two basic modes of biometrics -
  1. Verification
  2. Identification
