“ A human being is a single beingunique and unrepeatable” -ELEEN CADDY



Automated system and computers simplifiedour life

Need to provide security to the systems

Use of passwords are the preferred methodSharing and theft are common

Later introduction to the biometrics



Measurement of biological characteristicsIdentity verification

Veins , fingerprints , iris pattern , face pattern

voice patternFundamental properties of ideal biometrics:

Security:-resistance to forgery ,

accuracy practicality:- speed , cost , size ,enrolment , convenience



FINGERVEIN

RECOGNITION

A new biometric methodUtilizes finger vein patternUnique for each finger and for eachperson

Falsification extremely difficult



Meets anti-forgery by internal biometric Accuracy requirement is met

Offers great convenience-insensitive to

extraneous factors like dirt or greaseEffective as finger vein pattern remains samethrough adult years

Very fast

No enrolment problems

Cost effectiveness is excellent



Works by shininginvisible infrared light via finger

Hemoglobin in blood

absorbs infrared lightResult is image of unique pattern veins

It is captured by sensor



Capture of finger vein pattern:

# sensor captures finger vein image andpasses it to CPU memory

Normalization of image:

# normalized to accommodate geometricchanges or angle of finger

Feature pattern extraction from image:

# distinctive features of finger vein patternare extracted



# for eliminating variations in captured data.# result is standard finger vein template.

Pattern matching and outcome decision.

# captured finger vein template is matchedagainst previously stored template.

# if close match found ,user is authenticated.



FINGERVEIN :

Uses transmitted infrared rays

High contrast images

Capture of deeper veinpatterns

High tolerance to noise

Easier to matching algorithm

Median recognition attempt

duration is 1.23sMedian enrolment duration is33.3s

Finger vein devices are of

small size

PALMVEIN :

Uses reflected infrared rays

Reduced image contrast

Penetrates only shallow way under the skin

Susceptible to noise (dirt,roughness of skin)

Challenge to matching

algorithmMedian recognition attemptduration is 2.13s

Median enrolment duration is61.7

Palm vein devices are bulkier



PC login security Mobile phone login security

Door entry control

Bank security



High accuracy rateFast authentication speed

Unique and constant

No enrolment problemsEase of feature extraction

Resistant to criminal tapering

Falsification is difficult



Only be used if the person is living.



Finger printing : exterior to body-falsificationeasy-sweaty finger prints cannot beregistered.

Iris scanning: direct application of light intothe eyes, cause irritation.

Face and voice recognition: impersonation iseasy – accuracy rate limited-low security.



Finger vein has inherent properties toperform in areas that matters both security and practicality.

Proven with extensive applications in Japan.Quantitatively and qualitatively finger veinrecognition superiors all other methods.

Its potential of versatile reliable means of identification has positive implication inindustry ,commerce ,government and lawenforcement agencies.
