This document discusses palm vein recognition technology for biometric authentication. It begins by explaining biometrics and some common biometric techniques like fingerprints, iris scans, and voice recognition. It then introduces palm vein recognition which uses infrared light to scan the unique vein patterns in one's palm. The document details how the palm vein pattern is extracted, encrypted, stored and used for matching during authentication. It notes the advantages of palm vein recognition over other techniques in terms of accuracy, security and inability to forge. Finally, it discusses some applications and challenges of the technology.

2. Do u know Biometrics?
• Automated measurement of Physiological and/or
behavioral characteristics to determine or
authenticate identity is known as Biometrics.
• The behavioral characteristics measure the
movement of a user, when users walk, speak, type
on a keyboard or sign their name.

3. The physiological characteristics would be
the physical human traits like fingerprints,
hand shape, eyes and face, veins, etc

4. ❖ Biometric authentication technology focusing
on four methods:
❖Fingerprints
❖Face recognition
❖Voice recognition
❖Iris Recognition

5. Disadvantages of other techniques

6. Need for Palm-Vein Technology
• All of the above discussed techniques have
some problems which have to be overcomed.
• Apart from other techniques like IRIS scan in
which Cataract replacement, Finger scan
during Injuries etc can be an disadvantage ,
palm vein technique has no problems.

7. Technology Advantages Disadvantages
Fingerprint •Popular
•Cheapest
•Less Accurate
Voice •Non invasive •Least Accurate
Iris & Retinal
•Very accurate •Invasive
•Expensive
•Sensitive
Palm Vein
•Non-invasive
•Relatively Cheap
•Accurate
•Unfamiliar

8. What is Palm-Vein technology?
• In this technology ONE’S PALM is used as the
“PASSWORD” for verification.
• The veins present in the palm of the individual are
scanned & verified thus providing the access.
• Palm vein authentication has a high level of
authentication accuracy due to the uniqueness
and complexity of vein patterns of the palm.

9. ➢The palm vein authentication uses the vascular
patterns of the palm as personal identification
data
➢If there is a match then access is allowed, if not
access is denied.
➢This system is not at all dangerous. A near
infrared ray is a component of sunlight, whose
effect is much less than walking in sunlight.

10. Principle
• Unlike the skin, through which near-infrared light
passes, deoxygenated hemoglobin in the blood
flowing through the veins absorbs near-infrared
rays, causing it to be visible as black regions to
the scanner.
• Arteries and capillaries, whose blood contains
oxygenated hemoglobin, which does not absorb
near-infrared light, are invisible to the sensor,
hence we chosen “VEINS”.

11. Image of vein pattern

12. Basis of the Palm-Vein Technology
• An individual's palm vein image is converted by
algorithms into data points, which is then
compressed, encrypted, and stored by the
software and registered along with the other
details in his profile as a reference for future
comparison.
• Numbers and positions of veins and their crossing
points are all compared and, depending on
verification, the person is either granted or
denied access.

13. Working
• One should place his/her palm near to scanner.

14. • The scanner makes use of a special characteristic
of the reduced hemoglobin coursing through the
palm veins — it absorbs near-infrared light.

15. • The integrated optical system in the palm vein
sensor uses this phenomenon to generate an
image of the palm vein pattern and the
generated image is digitized, encrypted and
finally stored as a registered template in the
database.

17. • Normally, the captured palm vein pattern is
grayscale and subject to noise.
• Noise Reduction and Contrast Enhancement are
crucial to ensure the quality of the subsequent
steps of feature extraction.
• Also, the vein pattern extracted from infrared-ray
images is represented as dark lines.

Feature Extraction
Matching

19. • Feature extraction plays an important role in
palm vein recognition because the performance
of feature matching is greatly influenced by its
output
• Feature matching is achieved by check whether
the input image exist in the database to give the
permission to that person being authenticated.

20. Accuracy
Technology Advantages Disadvantages
PalmSecure .00008% .01%
Fingerprint 1-2% 3%
Iris .0001% - .94% .99% - .2%
Voice 2% 10%

21. Imaging Methods
• Imaging is the main part of this technique as
basically image of a vein pattern is obtained in
the first step.
• There are two imaging methods used for veins
1.Reflection
2.Transmission.

22. How secure is this technology?
• On the basis of testing the technology on more than
70,000 individuals, Fujitsu declared that the new
system had a false rejection rate of 0.01% and a false
acceptance rate of less than 0.00008%
• No two people in the world share a palm vein
pattern
• And if you registered your profile as a child, it'll still
be recognized as you grow

23. • It is difficult to forge for intruders.
• It is not affected by dryness or roughness of skin
or by physical injury on surface of the hand.

24. Applications

25. Disadvantages
• There are numerous factors that can affect the
quality of the captured image such as body
temperature, humidity, heat radiation, nearness
of vein to surface, camera calibration and focus.
• It is still relatively expensive and not available for
mass production yet.

26. Conclusion
• If this technology is introduced in our country we
can solve many problems such as password
protection in ATM.
• security in various fields and if we implement this
technology in government offices we can make
the employees to work according the government
timings.
• surely this technology will bring a revolution in the
field of science and technology in the near future.
