Finger print recognition procedure means automatic method of
verification of human finger prints. Finger print is one of the forms of
biometrics which is used for identification of an individual. It is the finger
print sensor which is used to capture a virtual image of an individual finger
print pattern. The image which is stored is referred as live scan. This scan is
then digitally processed with the help of some software to create a biometric
template of this scan which is further used for matching purpose. In order to
capture a finger print three fundamental or common patterns are followed one is
the arch pattern where ridges enter from one side of the finger, rises in the
center forming of an arc and then it exit via other side of the finger. Then is
the loop pattern where ridges enter from particular side of a finger, forms a
curve, and then exit from the same side. Last but not the least is the whorl
pattern where ridges enter circularly around a central point of the
finger. Next is the payroll management
system which is part of human resource software. This system basically collects
all the data of an individual employee then access the working hour of an
employee within a company, make assessment of the overall performance of an
employee, and it also manages the salary of an employee which it generate as a
paycheque.
Apart from this there is the presence of Access Control Systems
which restricts access of an individual without biometric check. This is
basically a type of security check. The reader basically study the biometric
finger print of an individual which it checks in the database for authorization
if it matches with the previous finger print then it permit entrance or else it
denies any legalized authorization. If a match is found with the access control
list then only the door of a company unlocks or else it sends an alarm by
flashing red light.
