A. Biometric Systems
A biometric system refers to the systems which consider a person’s any quantifiable physical
attributes that can be changed over into a computerized design for specific identification and
authentically verified. The biometric systems that are examined here are: -
1) Fingerprint
 A fingerprint biometric system is acquiring finger impression electronically. It is the most
commonly used biometric system.
 The local features of a fingerprint biometric are minutiae, ridge endings and ridge
bifurcations.
 The global features of a fingerprint biometric are ridge orientation and pattern of ridges.
 The fingerprints are used in different sectors like:-
 Government sector: - For voter registration, border control, e-passport¸ national ID.
 Business sectors: - To maintaining a record of, payroll management, time and
attendance, human resource management.
 Finance and banking sector: - For customer identification, employee identification,
non- account holder identification, ATM machines.

 The advantages of fingerprint biometric systems are:-
 High in uniqueness and permanency
 Its universal form of the system used widely acceptable by every organisation.
 High in the factor of accuracy.
 The requirement of storage is low.
 The disadvantages of fingerprint biometric systems are:
 False readings may occur.
 Costly
 Time-consuming
 For a few people, interruption happens because of the criminal examination.
2) Hand geometry:
 Hand geometry biometric system is a compelling identification framework in which an
individual is recognized by the hand acknowledgement.
 It is based on the extraction of finger-widths and palm- print features of hands.
 The proposed hand geometry system follows two types:-
 Hand geometry identification using shape context feature
 Hand geometry identification using shape moment feature
 Hand geometry is used for higher accuracy services at airports, government offices and in
many international corporations, the point of sales applications and employee time recording.
