Biometric access controls are used to control the entrance and exit of buildings and private estates. They can also be used to secure vulnerable systems (like lifts or computers) and lock down dangerous machinery for cleaning and maintenance. Using access control systems you can make your property more secure, improve staff punctuality and help reduce your operational costs.
Various Biometric systems exist and are widely in use today, for example Fingerprint, Facial, Voice, Iris and Hand geometry. Each system has it’s advantages and disadvantages. Cost, reliability, environment, security, and ease of use of just some of the factors to consider when selecting a Biometric system.
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.
