• something you know, like a password, PIN, or code.
• something you have, like a swipe card, smart card etc.
• something you are, which is biometrics.
three main types of authentication available today are:
What is a biometric?
Biometrics • Is the term given to the use of
biological traits
OR
behavioral characteristics
to identify an individual.
The Biometric importance
The security is needed in every place.
Eliminate the existing problems, Like those which can be taken, stolen, borrowed or even forgotten.
The Biometric importance (Cont.)
Improves convenience, security, and privacy.
The first and most critical link in the security chain.
Biometrics History
The term "biometrics" is derived from the Greek words
(life) and metric means (to measure).
bio which means
Biometrics History (Cont.)
the first known example of biometrics in practice was a form of finger printing being used in China in the 14th century.
Biometrics History (Cont.) In the 1890s, 'Bertillonage', created a method of bodily
measurement with the criminals who repeated the crimes with different names and looks.
Biometrics History (Cont.)
After this, finger printing, which was developed by Richard Edward Henry of Scotland Yard.
Physical Characteristics
Fingerprint Recognition:
Fingerprint Recognition is the identification by using patterns of friction ridges and valleys on an individual's fingertips which are unique to that individual.
Database
Fingerprint Recognition steps:
Face Recognition: Face recognition is scanning a persons face
and matching it with a library of known faces.
Face recognition process:
Database
Input face image Extraction of
face image
Extraction of face features
Positive
negative
Signature Identification:
Signature identification: is the analyses of the way a user signs his or her name.
• the angle at which the pen is held,
• the number of times the pen is lifted,
• the time it takes to write the entire signature,
the pressure exerted by the person while signing,
Signature Verification Process (Cont.)
Biometric trait

Profile
Iris Identification: The iris is the colored ring of textured tissue
that surrounds the pupil of the eye.
Iris Identification Steps:
Database
Input of face image
Detection of eye regions
Put iris in focusRecognition of
iris pattern
accept
reject
Veins Recognition:
Venial Recognition: A system for Identification using a person’s unique vein patterns.
Veins as a biometrics tool involve the measurement of the blood vessels on the back of your hand.
Vein Recognition System:
Database
Input of palm picture
The output picture
Generate veins structure

Not match
Behavioral Characteristics
Voice Recognition:
Voice Recognition: is the Identification using the acoustic features of speech that have been found to differ between individuals.
Voice Identification System
Database
Construct voice reference template
Applications of Biometric
Applications of Biometric
Access control :• Disney World (fingerprint scanner).
Applications of Biometric (Cont.)
Time and attendance management
• Hospitals
Other Applications
Airports:• Airport (iris recognition)
ATMs:• (face recognition)
Other Applications (Cont.)
• Fujitsu has developed a mouse that can verify a person's identity by recognizing his pattern of blood veins.
Advantages of biometrics
1. Uniqueness
2. Time security
3. Reduce Fraud
4. No Forgotten Password
5. Accuracy
6. Accountability
Disadvantages of Biometrics
1. costly.
2. Facial imaging can also hinder accurate identifications.
3. Missing body part problem.
Disadvantages of Biometrics (Cont.)
4. False acceptances and rejections.
5. The amount of comfort.6. The scanning of eye is fearful.
7. The nervousness that people feel about the scanners identification.
Future Aspect
Conclusion
1) How are biometrics collected?2) What if identical twins use a
biometric device?3) Using biometric technology can help
save the environment?
What is an advantage of using Biometrics?
a) Biological signatures are uniqueb) Criminals are afraid of
biometricsc) It is very inexpensive and easy
to use
