Biometric technology provides a range
of automatic methods which can be used to measure and examine a person’s
physiological and behavioral characteristics (Alhussain & Drew, 2009). It
usually involves a scanning device and related software which can be used to get
together information that has been recorded in digital form. According to
Alhussain and Drew (2009), by using biometric technology, e-government aims
to give its citizens enhanced services with resourceful and protected access to
information by providing reliable classification of individuals as well as the
ability for calculating and protecting the integrity of sensitive data stored
in information systems.
In fact, in the law
enforcement community, matching fingerprint images or parts of palm print
images is the most frequent method to identify suspects and bring guilty
criminals to justice. In some movies, we may also see a criminal telephone the
victim and the police record the voice of the criminal and search for the
criminal according to voice recognition. These scenes are examples of
identifying people using their exceptional physical features (e.g.,
fingerprints, palm print, and face) or behavioral trait (e.g., voice) and automatic
biometrics can help in this scenario. When
automatic biometrics technology became more and more grown-up in the
law enforcement area, it was introduced into civilian applications by the biometrics product vendors.
