Biometric technologies focus on verifying and identifying people using their biological (anatomical, physiological and behavioral) features. Biometric technologies are generally considered to be the implementation of pattern recognition algorithms because they are intended to identify people.

1. Biometric Technologies
and Applications

2. Overview
Biometric technologies try to generate computer models of
human physical and behavioural characteristics in order to
reliably identify people. Biometric technologies are
generally considered to be the implementation of pattern
recognition algorithms because they are intended to
identify people.
The ability to improve the reliability and accuracy of the
various types of biometrics systems while testing their
vulnerabilities under different environmental conditions is
critical, since biometrics is an essential part of law
enforcement and security communities.

3. Key Points
1. Biometrics technologies try to generate
computer models of human physical and
behavioural characteristics in order to reliably
identify people.
2. The word “biometrics” comes from the Greek
words “bios” and “metric” meaning life and
measurement. This translates directly into “life
measurement”.
3. Ethical issues of synthetic Biometrics
· Prevention of undesirable side
effects,
· Targeting areas of social concern in
biometrics,
· Generating several copies of original
information,
· Threats of forgery etc.

4. Key Points
4. A biometric identification device can
measure-
· Individual biometric information
· Compare the measurement with one
or more stored biometric reference
templates,
· Decide whether they match
sufficiently to indicate that they
represent the same person
· Whether or not identification has been
recognized or verified.

5. Key Points
