2. Biometric
• The term "biometrics" is derived from the Greek
words bio (life) and metric (to measure).
• Biometrics refers to technologies for
measuring and analyzing a person.
• It is based on person physiological and behavioral
characteristics.

3. physiological characteristics
• Fingerprint Recognition is the
identification by using patterns of
fiction ridges and valleys on individuals
fingertips which are unique to that
individual.
• Face Recognition uses the visible
physical structure of the face and
analyses the spatial geometry of
distinguishing features in it to identify
an individual.

4. physiological characteristics
• Iris Identification is the colored ring
od textured tissue that surrounds the
pupil of the eye.
• Hand Geometry identifies users by the
shape of their hands. Hand geometry
readers measure a user's hand along
many dimensions and compare those
measurements.

5. Behavioral Characteristics
• Voice Recognition is the identification
using the acoustic features of speech
that have been found to differ
between individual.
• Signature Identification is the
analyses of the way a user signs. The
process used by a biometric system to
verify a signature is called dynamic
signature verification (DSV).

6. Advantages
• Increase security.
• Eliminate problems caused by lost of IDs or forgotten
password.
• Make is possible automatically, to know who did what,
where and when.
• Reduce password administration cost.
• Replace hard to remember password which may be
shared or observed.

7. Disadvantages
• Costly.
• The scanning of eye is fearful.
• Facial imaging can also hinder accurate identification.
• Missing body part problems.
• False acceptances and rejection.
