ABSTRACT
One of the most difficult problem in humanidentification is fingerprint .
Fingerprint Matching is significantlyinfluenced by fingertip surfacecondition,which may very depending onenviromental or personal causes.

Cont..
Minutae based matching has difficulty inquickly matching of two fingerprint images.
I proposed filter based algorithm andEucledian distance algorithm using toshow an accuracy of fingerprint matching..
Finally I showed that the ReliableFingerprint Matching is achieved by thisproject.

Fingerprint Classification
Fingerprint is an impression of ridges on theskin.it can be classified in to 5 categories.
arch tented arch right loop Left loop
whorl

EXISTING SYSTEM
The Existing system uniaueness of theridges flow pattern is the basis of forensicapplication on fingerprints,they taken small
images of fingerprint and gave solution tothe valid minutae points.

PROPOSED SYSTEM
Fingerprint verification using EnhancedModified Direction feature and Neuralbased classification with fingerprintimages.
I proposedHow we extract the minutiae points, &How we establish whether two
` impression belong to the same finger.

contd..
By using gabor filters size of the imagehas calculated.
By using Eucledian distance algorithm Isearch the position of ridges and to whichidentify the nearest number of ridges hastaken to calcuate distance between theridges.
Knowing the distance after that Icalculated Ridges and pore configuration.

Features of Fingerprint Matching
Shape - Lot of variations in the shape of
minutiae. Ridges - Orientation is defined in the
ridge area.
Configuration-Measurement accuracycan be seen by comparing.

cont The uniqueness of a configuration or ridges
depends on several factors such as whorl ,loop,arch involved in the respective of shape andsizes.
These factors matched with databse and giveauthentication to user,But sometimes notmatched in live scan process,
In my project any type of fingerprint condition isthere,it is sequentially matched and giveauthentication to user.

EXTRACTOR MODULE
Fingerprint enhancement is essential toensure the robustness of fingerprintidentification with respect to the imagequality.
Gabor filter is introduced in this paper Gabor filtering is the most popular method
in fingerprint enhancement

ALGORITHM
Pattern or Image based algo:Step 1: Pattern based algorithms compare
the basicfingerprint patterns (arch,whorl, and loop) between apreviously stored template and acandidate fingerprint.
Step 2: This requires that the images be
aligned in the same orientation .

Cont Step3: The algorithm finds a central point
in the fingerprint image . Step4: In a pattern-based algorithm, the
template contains the type, size,and orientation of patterns within thealigned fingerprint image.
Step 5: The candidate fingerprint image is
graphically compared with the templateto determine the degree to which theymatch

MATCHING MODULE
MINUTAE CONFIGURATION: When Matching is based on minutae,the
template consist of vital information aboutthese ffeatures.
{Rp,R o, R t.. R p (ME),R o (ME ), R t (ME)}R p- Ridge position
Ro-Ridge orientationRt -Type of ridgeME Minutae enrolled

PORE CONFIGURATION
Neighboring pores are separated byconstant distance d.
D-distance between neighboring pores. Value of distance d is calculate by using
this formula
d-(area of the ridge/No .of .pores)confgtn- distance* N p* 0.48

ACCURACY MODULE
A Matching score provides the the degreeof matching between two segments with arange of complete match.
Matching score = (Minutae config value + pore config value ) * 100

CONCLUSION
This project demonstrates an efficient fingerprintrecognition using minutiae matching, the proposedtechnique is particularly effective for verifying qualityfingerprint images, Every feature was required to matchfor the entire set to match
Proposed enhancement of algorithm for detection ofminutiae give good results in reducing the false minutiaeimprovements, due to low quality level can also refer tothe unification of image filtering and segmentationalgorithm and minutiae detection, In order to make theentire process faster
