Biometric Applications

 

The first application of biometrics was for criminal investigation and law enforcement: to use “latent” fingerprints found in a crime scene to help identify who might have left them behind. Today this application remains an extremely important one, but with the help of modern digital computing we‟ve also learned to use biometrics for another very useful purpose: to establish trust in a person‟s identity. Modern biometrics, at their core, are about using an individual‟s physical characteristics or behaviour to generate a set of numbers that can be used (with the help of a computer) to uniquely identify them consistently over time. Establishing trust in identity—proving we are the person we say we are—is useful.
