• A biometric identification system provides an automated method
of recognizing an individual based on their unique physiological
characteristics
 Metrics related to human characteristics
 These metrics are Distinctive and Measurable (label
and describe individuals)
What is Biometric?

4
Why Biometric?
• Traditional, security is by what we:
–Know (PIN, Password)
–Have (Key, smart card)
• Both of these security measures can be hacked, stolen, forgotten,
duplicated and have too many.
• Modern, security is by we:
–Are (Body)
• It is not easy to create a copy because its unique and high
accuracy.

5
Type of Biometric?
1. Finger print
2. Palm veins
3. DNA
4. Iris recognition
5. Facial recognition
6. Voice recognition
7. Signature recognition
8. Palm print

Uniqueness Finger Skin Pattern

• Human finger skin consists of friction ridges with pores.
• These ridges are formed in the ninth week of a fetal
development life, and remains the same all life long.
• A severely injured skin may be reconstructed to the same
as before.
• Identical twins have different fingerprints and no two
people have the same fingerprint.
• Every individual’s fingerprint is highly unique and suitable
for use as a form of authentication.

8
Fingerprint Security
• Deny Intruders
– Higher Accuracy computation
• 97% will return correct results
• Prevent Re-construction of fingerprint data
– Image protection
• Minutiae is retrieved and template created
– Encrypted data
– Image destruction
• Cannot reconstruct the fingerprint from data
• Fake Fingerprints Detection
– Ignore Latent Print Residue
• Cannot steal from previous user
– Detect fake/amputated finger
• Sensors detect presences of

Optical Fingerprint Sensors
Problem:
1. Scratched or dirty touch
surface can cause bad image
2. Easily fooled by fake finger
3. Bulky design, only suitable for
larger static installation
Function:
1. Reflected image of fingerprint captured by
camera from the underside of a prism.
2. Image is stored for comparison with
database.

3 Levels of Fingerprint classification
1. Loops ,Arches , or Whorls
2. Individual characteristic (Minutiae)

18
Basic Idea
• After these classification, a key is generated by the software algorithm.
• After finger print reader read your fingerprint, software will compare
with database.

Scan and Classify Generate a unique
user Key
Unlock access

19
Cryptography
• There is two keys:
Public key
Private key (Fingerprint key)
• The basic idea is:
 Sender encrypts data with his receiver’s public key and send out.
 Receiver will use his/her private key to decrypt the data. No one
can decrypt without receiver’s private key!

• Software Classification

• http://www.bioelectronix.com/what_is_biometrics.html

Fingerprint Matching Software
• The most commonly used are:
1. Minutiae matching (commonly used)
2. Pattern matching
http://www.biometric-solutions.com/solutions/index.php?story=fingerprint_recognition
http://biometrics.mainguet.org/types/fingerprint/fingerprint_algo.htm

Advance Minutiae Based Algorithm (AMBA)
• Two processes
1. Feature Extractor
2. Matcher
http://www.supremasolution.com/

AMBA – Feature Extractor
• Feature Extractor
– Capture Image
– Enhance Ridge (Normalization, Local orientation estimation,
Local frequency estimation, Region mask estimation and
filtering)
– Extract Minutiae (Classification)
http://http://www.supremasolution.com/
http://www.cse.iitk.ac.in/users/biometrics/pages/finger.htm

AMBA - Matcher
• Matcher
– Used to match fingerprint
– Trade-off between speed and performance
– Group minutiae and categorize by 12 types
• Large number of certain type can result in faster searches
http://www.supremasolution.com/

Example: Apple ID touch
• Secure Enclave - using its microprocessor (A7)
to create protection to user’s data
• When device is locked:
– Data protection keys are wrapped (encapsulated)
– Data are not accessible
• When device is unlocked by the fingerprint
sensor:
– Data protection key are unwrapped (decapsulated)
– Iphone is unlocked and data is accessible

How Fingerprint Biometric is used
• Enrollment
– Storing of fingerprint in
database
• Verification
– Known Identification of
person
– Compare the person’s
fingerprint in database
– One to one comparison
• Identification
–Unknown Identification of
person
– Search through database
for a match
– One to many comparison

Optical Resolution vs Accuracy
http://biolab.korea.ac.kr/pubs/JainFpMatching_IEEEComp10.pdf
Jain, Feng, Nandakumar, Anil K. Kain, Jianjiang Fengm Karthik Nandakumar, 2010. Fingerprint Matching. Computer, 0018-9162, 36-44.
[a] http://itlaw.wikia.com/wiki/False_non-match_rate
[b] http://itlaw.wikia.com/wiki/False_match_rate
False Non-Match Rate (FNMR) is the failure of a biometric system to identify a biometric
subject or to verify the legitimate claimed identity of a biometric subject.
False Match Rate (FMR) is the proportion of the completed biometric non-match
comparison trials that result in a false match. [b]
False Positive Identification Rate (FPIR) occurs when the system finds a hit for a query
fingerprint that is not enrolled in the system.
False Negative Identification Rate (FNIR) occurs when it finds no hit or a wrong hit for
a query fingerprint enrolled in the system.

Summary of Fingerprint Applications
-- Changing Lifestyle
• People are willing to use fingerprint technology instead of traditional way in
daily life, this is because fingerprint technology is reliable and convenient.
• Lifestyle is changing with fingerprint technology widespread used and hand
phone is a major base of this technology.

Without fingerprint With fingerprint
Mobile Phone based Applications
-- Unlock hand phone
• Since security concern, Apple and some other companies change hand phone
password from 4 number to 6 number which means users need longer time to unlock
their hand phone.
• Unlock your phone with fingerprint to save time. Hand Phone can be unlock while you
press home bottom
• Hand phone integrate reliable technology -- fingerprint function is a key to open the door
of new lifestyle.

-- Fingerprint technology in Banking
Bank Branch Bank Mobile APP
• People save time and easily to manage their bank account
by hand phone
• Banks can reduce No. of branches which means lower cost
for banks.

• Compared with other Biometrics
technologies, fingerprint
technology widely used in
banking
• Asian and US are largest market
in fingerprint banking.

48
-- Mobile Bill Payment
AXS machine AXS online
• Without fingerprint, people don’t want to pay bill by mobile
phone, although some App have function of bill payment,
people are not willing to save credit card info in those App.
They have big concern on safety!
• With Fingerprint, people can pay bill by Mobile phone without
safety concern.

49
-- Mobile Manage Stock
Buy/Sell at Stock market Buy/Sell on Handphone
• More easier to manage your Stock
account by hand phone. Fingerprint
replace password, Safer than password
