What is biometric security?

The basic premise of biometric authentication (the term is derived from the Greek word “bio” meaning life and “metric” meaning to measure) is that every person is unique and each individual can be identified by his or her intrinsic or behavior traits. Biometric technology is able to recognize a person on the basis of the unique features of their face, fingerprint, signature, DNA or iris pattern and then impart a secure and convenient method for authentication purposes.
Biometrics is therefore the measurement and statistical analysis of a person’s physical and behavioral characteristics. For example, fingerprint recognition systems work by recognizing the characteristics of a person’s finger.
The finger verification software will compare these characteristics with data already stored on the server and if the two fingerprints are sufficiently similar, the biometric security system will then declare it a match.
