PART-2
Part A
Fingerprint
The word Biometric has two parts i.e. Bio and Metric. The word bio is defined as life and
metric is used to measure something. The Biometrics is used to determine the actual identity
of a person. This aspect of identification is mostly used than any other methods like pattern
drawing, passwords and pin numbers. These type systems used to detect the identification of
the validate users in the system. Biometric system is divided into various types which contain
fingerprint recognition, iris pattern, face recognition, vein pattern etc.
Figure 1: Biometric Sensors
Biometric of a person is used to recognize a person’s verification. A biometric sensor is
tending to change a person into electrical signals. Methods for biometric includes fingerprint
identification, face recognition, iris recognition, voice recognition etc. These sensors use
many different measures many different aspects like speed, temperature and many different
types of energies. In every type of biometric devices, at least one type of sensor device is
used. The devices which use biometrics use many applications like high-quality camera for
face detection, capture voice in microphones. Some biometrics is specially designed to
identify special features in recognizing technology. (Higgins et al., 2009)

Types of Biometric sensors:
Using Biometric systems, it is feasible to access the system in authenticating form. These
systems are classified into two forms i.e. Behavioral and physiological.
