Biometric Security System


Seminar topic for Computer Science department

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 behaviour 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 behavioural characteristics. For example, voice recognition systems work by measuring the characteristics of a person’s speech as air is expelled through their lungs, across the larynx and out through their nose and mouth.

The speech verification software will compare these characteristics with data already stored on the server and if the two voiceprints are sufficiently similar, the biometric security system will then declare it a match.
