Biometrics

  1. 1. BIOMETRICS
  2. 2. BIOMETRICS
  3. 3. DEFINITIONBiometrics is the identification or verification of human identity through the measurement of repeatable physiological and behavioral characteristics.
  4. 4. AUTHENTICATIONAuthentication is validating or figuring out the identity of a person. There are two types of authentication methods :
  5. 5. LEVELS OF AUTHENTICATION
  6. 6. CATEGORIES OF BIOMETRICS
  7. 7. BASIC FEATURES1. UNIVERSALITY : Every person should have that characteristic, people who are mute or without a finger print should be accommodated in some way.2. UNIQUENESS : Generally, no two people have identical characteristics but two identical twins are hard to distinguish.3. PERMANENCE : The characteristic should not vary with time. A person’s face, for example may change with time.4. COLLECTIBILITY : The characteristic must be easily collectible and measurable.5. PERFORMANCE : The method must deliver accurate results.6. ACCEPTIBILITY : The general public must accept the sample collection routines.7. CIRCUMVENTION : The technology should be difficult to deceive.
  8. 8. COMPONENTS
  9. 9. WORKING OF BIOMETRICS
  10. 10. BIOMETRICS IMPLEMENTATION FACTORS-> LOCATION-> SECURITY RISKS-> TASK ( IDENTIFICATION OR VERIFICATION )-> EXPECTED NUMBER OF USERS-> USER CIRCUMSTANCES-> EXISTING DATA
  11. 11. BIOMETRIC MODALITIESCOMMON BIOMETRIC MODALITIES: OTHER MODALITIES: FINGERPRINT  GAIT OR BODY FACE  VASCULAR IRIS  RETINA VOICE  FACIAL THERMOGRAPHY SIGNATURE HAND GEOMETRY
  12. 12. FINGERPRINT RECOGNITIONFOR FINGERPRINT RECOGNITION,THE FOLLOWING THINGS ARE LOOKED AT ( AS SHOWN IN FIGURE 1) : CROSSOVER CORE BIFURCATION RIDGE ENDING ISLAND DELTA
  13. 13. DISADVANTAGES: Racial issues. Dirt , grime and wounds. Placement of finger. Too big a database to process. Can be spoofed – livens important!
  14. 14. FACE RECOGNITION
  15. 15. ISSUE WITH FACE RECOGNITION:
  16. 16. IRIS RECOGNITION
  17. 17. CONTACT LENSES IS AN ISSUE WITH IRIS RECOGNITION.
  18. 18. VOICE RECOGNITION
  19. 19. ISSUES WITH VOICE RECOGNITION: Local acoustics. Background noise. Device quality. Illness/emotional behavior. Time consuming enrollment. Large processing template.
  20. 20. SIGNATURE RECOGNITION-> Signature measures(dynamic) Speed Velocity Pressure-> Captures images(static)-> High user acceptance
  21. 21. DISADVANTAGES: Signature variable with:- Age- Illness- emotions Requires high quality hardware. High false rejection rates as signatures are very dynamic.
  22. 22. HAND GEOMETRY RECOGNITION
  23. 23. The requirement of large scanners is the issue in hand geometry recognition.
  24. 24. WHY BIOMETRICS ? Most definitive, real-time tool available today. It can be combined with other tools to form more secure, easier to use verification solutions. Recognizes individuals definitively. Based on physiological and behavioral characteristics.
