1.0 Biometric systems
The word biometric is a Greek word which comes from two words namely bio and metric, where
bio means life while metric means measuring. The biometric sensors are used for identifying the
physical behavior features or characteristics of an individual. We can use the Biometric systems
over those traditional methods that included pins and use passwords because it gives an exact
and it’s very case sensitive. The biometric systems are built on the basis of the design and hence
we choose if it is for identification or as an authentication system. The biometric systems are
used divided in to various types such as the:
Fingerprints
Hand geometry
DNA
Iris Pattern
Face Detections
Signature Dynamics
DNA
Voice Pattern
Biometric sensors are also referred to as the Access control systems which can be further
classified in to two types that is namely the physiological and behavioral biometrics. In the case
of physiological biometrics we have the face recognition, fingerprint, iris recognition, hand
geometry and DNA. Whereas in the case of behavioral biometrics it includes such as the
signature, voice recognition and keystrokes.

1.1 Fingerprint Recognition.
This is known to include fingerprint image of the persons and recording the features such as the
aches, whorls and loops along the edges outlined and furrows. To match the fingerprint we can
attain it using the following three technologies.
i. Munitiae based fingerprint matches store a plane that may include set of points
and setting the point that may corresponds in to template
ii. Correlation based fingerprint that matches the overlays of the two images of
fingerprints and the association between the pixels that bare equivalent when
calculated.
iii. Ridge Feature based fingerprints that matches the innovative method capturing
the ridges.
Figure 2 Fingerprint Recognition
In capturing the fingerprints we have to present the methods that will employ optical sensors
where they use a CMOS image sensors or a CCD. The following are some of the advantages and
disadvantages of Fingerprint recognition
