WEEK 2
Introduction
Fingerprint directional
field is defined as the local orientation ridge valley structure,
explain the gross structure or form the basis of fingerprints [1]. It is widely
used in fingerprint registration or reference point location, classification,
and is suitable. Locations are presented in different reference point for the
sine component orientation among the adjacent field.
Automatic fingerprint recognition system is often confronted
with problems of translation during fingerprint acquisition [2]. Therefore, the
first step necessary for fingerprint alignment is to find the core point of the
directional field of fingerprints based on system index. However, the system
index is able to find the singular points [3], thus the problem arises for
fingerprints of the gate.
As for the fingerprint
analysis, principle component analysis seems to be the method of choice. A method
is proposed based on the estimated high-resolution field direction for the
computation of fingerprints with the instructions in each pixel location [4].
Gradient corresponding with the axis of fingerprints with the function with a
probability of belong with the largest value.

Fingerprint recognition or fingerprint authentication refers to
the automated method of
verifying a match between two human fingerprints [5].
Fingerprints are one of many forms of biometrics used to identify individuals
and verify their identity. The three basic patterns of
fingerprint ridges are the arch, loop, and whorl. An arch is
a pattern where the ridges enter from one side of the finger, rise in the
centre forming an arc, and then exit the other side of the finger.
The loop is a pattern where the ridges enter from
one side of a finger, form a curve, and to exit from the same side they enter.
In the whorl pattern, ridges form circularly around a central point on the
finger [6]. Scientists have found that family members often share the same
general fingerprint patterns, leading to the belief that these patterns are inherited [7].
The problems with
conventional system are the owner lost the keys and the vehicles are not
protected from stolen. With thumbprint system, it starts the engine as well as
the vehicles are fully protected by his owner.
This system requires
key only to save the data. After the data are stored at ROM, owner can start
the engine by using his thumbprint. The thumbprint system is easily
programmable and can store up to four different thumbprints [8]. Programmed
thumbprint can be added deleted and the system can be easily disabled by the
principle owner.
The objective of a thumbprint system is to provide
user a new security system that can prevent the vehicle from be stolen. The
system is a great solution for individuals or companies looking to add
additional security to their vehicle.
