Putting a finger on it – the loops and whorls of biometrics
Glossary
algorithm. A logical, step-by-step procedure used to solve problems in mathematics and computer programming. In the case of biometrics the algorithm refers to a computer program designed to turn raw data into code that can be used more easily by identification/verification software.
biometrics. The application of statistical methods to biological observations and phenomena.
capacitor. A device for storing electrical energy. For more information see How capacitors work (How Stuff Works, USA).
CrimTrac. Australia's major national policing initiative. CrimTrac includes the National Automated Fingerprint Identification System, and a National Criminal Investigation DNA Database. For more information see About us (CrimTrac, Australia)
digitise. To transcribe data into a digital form (represented as a series of numerical values) so that it can be directly processed by a computer.
