biometric Recognition Technologies and
Applications

• AUTOMATED PROCESS OF IDENTIFYING

2
What is Biometrics ? 

• Biometrics
• Biometrics" is derived from the Greek words
  'bios' and 'metric which means life measurement"
  in other way , Biometry Bio(life) Metry (to
  measure).
• Is the term given to the use of
• biological traits
• OR
• behavioral characteristics
• to identify an individual.
• Biometrics biomeans life and metrics to
  measure.

Characteristics of Biometrics

• Biometric technology measuring and analyzing
  biological data of human body, its capture
  identify automatically through integrated
  biometric device which based on two major
  characteristics .
• Physical characteristics
• Behavioral characteristics

Mode of Biometric System

• Identification
• One-to-many comparison
• It search for a sample against a database of
  templates
• It identifies an unknown individual.
• For e.g. who is x?
• Verification
• One-to-one comparison
• It compares a sample against a single stored
  template
• It verifies that the individual is who he claims
  to be
• For e.g. is this x?

Why Use Biometrics?

• Biometrics is a method of direct human
  identification.
• Biometric access control systems, providing
  strong security at entrances. 
• Biometrics help to no need to remember passwords,
  or PINs. Biometrics cannot be lost, stolen or
  forgotten
• Automated identification can be done very rapidly
  and uniformly, with a minimum of training.
• Discourages fraud
• Enhances security

Applications of Biometrics Technology
8
Fingerprint Identification

• Fingerprint recognition is a method of biometric
  authentication that uses pattern-recognition
  techniques based on images of human finger vein
  patterns beneath the skin's surface. Finger vein
  recognition is one of many forms of biometrics
  used to identify individuals and verify their
  identity.

Fingerprint Technology Uses

• Door Locks
• Access Control
• Computer work stations
• Time Clocks
• In room safes
• Payment Systems

11
Hand Geometry

• Person identification using hand geometry
  utilizes hand images to extract a number of
  features such as finger length, width, thickness,
  finger area etc. Scan hand surface area-to verify
  that the person using the device is really who he
  or she claims to be.

12
Work Of Hand Geometry System

• The user places the palm of his hand on a metal
  surface which has guidance pegs on it.
• the device can reads the hand attributes.
• The device then checks its database for
  verification of the user.
• The process usually takes less than 5 seconds.

13
Facial Recognition

• Facial recognition systems
• Face Recognition is physiological characteristics
  of human that identify by predefine computer
  programs and analyze human faces for the purpose
  of identifying them. These include the
  position/size/shape of the eyes, nose, cheekbones
  and jaw line.

14
Facial Recognition Process

• Facial recognition systems

15
Voice Recognition

• Voice recognition system It uses the pitch,
  pattern, tone, frequency, rhythm of speech for
  identification purposes.
• A telephone or microphone can act as a sensor.
• Speaker recognition is often used where voice is
  the only available biometric identifier, such as
  telephone.

16
Biometrics Iris Recognition

• There are two different types of eye scans
  retinal and iris, It measures the iris pattern of
  the eye i.e. the colored part of the eye that
  surrounds the pupil.
• The iris scanner analyzes features like rings,
  furrows, and freckles existing in the colored
  tissue surrounding the pupil.

17
Signature verification

• Signature recognition is a behavioral biometric.
• Signature to identify note the angle at which the
  pen is held, and count number of times the pen is
  lifted and how much time it takes to write the
  entire signature
• Actual signature recognition is carried out by
  writing on a pressure sensitive pad with a pen or
  stylus.

18
Advantage of Biometrics

• Biometric identification can provide extremely
  accurate, secured access to information
  fingerprints, retinal and iris scans produce
  absolutely unique data sets when done properly
• Current methods like password verification have
  many problems (people write them down, they
  forget them, they make up easy-to- hack
  passwords)
• Automated biometric identification can be done
  very rapidly and uniformly, with a minimum of
  training.

19
Disadvantage of Biometrics

• The finger print of those people working in
  Chemical industries is often affected. Therefore
  these companies should not use the finger print
  mode of authentication.
• Biometrics is an expensive security solution.
• For people affected with diabetes, the eyes get
  affected resulting in differences.
• It is found that with age, the voice of a person
  differs. Also when the person has flu or throat
  infection the voice changes or if there are too
  much noise in the environment this method may not
  authenticate correctly. Therefore this method of
  verification is not workable all the time

20
Conclusion

• Biometric Solution read Biological factor and
  digitally identify human nature.
• Biometric Technology is very inexpensive and easy
  to use for many application area.
• Criminal identification
• Prison security
• ATM
• Aviation security
• Border crossing controls
• Database access
• Home/Office
