2. Biometrics combination of two Greek words:
Bio means “Life” and
Metrics means “To Measure”.
Biometrics are automated methods of identifying a
person or verifying the identity of a person based on
a physiological or behavioural characteristic.

3.  Authentication is the act of confirming
something what it claims to be.
 It is the process of giving someone identity so
that he or she can access that particular
application or data.
 For e.g.: giving identity-card to a student of an
institute.

4. Biometric systems uses three steps:
 Enrollment: It records basic information about you,
like your name or an identification number.
 Storage: Some systems also record this data onto a
smart card that you carry with you.
 Comparison: It either accepts or rejects that you are
who you claim to be.

6. Systems uses three components:
 A sensor that detects the characteristic being used
for identification.
 A computer that reads and stores the information.
 Software that analyzes the characteristic, translates
it into a graph or code and performs the actual
comparisons.

7. Each biometric has its strengths and weaknesses,
and the choice depends on the application.
 DNA Fingerprinting
 Face Recognition
 Fingerprint
 Iris Recognition
 Signature Verification
 Voice Recognition

8.  Deoxyribonucleic Acid (DNA) is the one-
dimensional ultimate unique code.
 DNA is very much accurate.

9. It is based on the location & shape of Facial
Attributes like eyes, eye brows, nose, lips, etc.

10.  A fingerprint is the pattern of ridges and
valleys on the surface of a fingertip.
 It is very easy to use.
 The device is very cheap and portable.
 The device used to recognize Fingerprints
consumes less power.

12.  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.
 It is very easier and cheaper.

13.  National ID card.
 Driver’s license.
 Social security.
 Computer network login.(Fingerprint verification system)
 Electronic data security.
 Internet access.
 ATM .(face recognition)
 Credit card.
 Internet banking.

14. Directly authenticates the person.
Difficult to steal; thereby making biometrics
authentication very strong.
Portable, and is unlikely to be lost.
user cannot share or forget his retina or fingerprint, while
a password and username are easily forgotten.
Comfort.
Accuracy.

15.  Costly
 Facial imaging can also hinder accurate
identifications.
 Missing body part problem
 False acceptances and rejections.
 The scanning of eye is fearful.

16. Biometric Authentication are:
Successful applications.
Decreasing costs and increasing convenience.
Increasing both privacy and identity security.
Benefit from this technology .
“Your body as password”? Now latest work based upon
ECG.
