1. BIOMETRICS Presented by: Anoop Sathyan S7 EC

5. In late 19th century, distinctiveness of Fingerprint discovered

6. Much developed in 20th Century

8. Universality

9. Distinctiveness

10. Permanence

11. Collectability

12. Practically

13. Performance

14. Acceptability

16. Physiological or Behavioral based person recognition

17. Physiological - Fingerprints, Retinal & Iris Pattern, Hand & Finger Geometry, Facial Recognition

18. Behavioral – Voice Patterns, Signature

19. Details entered into a Database

20. Compared with entered Details

22. Modes:

23. Verification Mode

27. False Match: Biometric Measurement from two different persons to be from same person

29. Vein Thermogram

30. Face Recognition

31. Fingerprint

32. Hand & Finger Geometry

33. Iris Scan

34. Retina Scan

35. Signature Verification

37. Identical Twins have same DNA

38. Benefits:

39. Accurate

40. Weakness:

41. Not in Real-Time

42. Physical sample should be taken

44. When exposed to IR rays, veins appear black

45. Merits:

46. Can be done only if person is alive

47. Difficult to forge

49. Thermogram can also be used

50. Merits: Can be taken from distance

51. Demerits: Can’t be used for identification but can be used for verification

53. Fingerprint of Identical Twins are different, even it differs from finger to finger

54. Benefits: Easy to Use, Cheap, Small Size, Low Power, etc

55. Weakness: Distorts due to Ageing, Cuts, Burns, etc

57. Merits: Very Simple, Easy to Use, Cheap, etc

58. Weakness: Lack of Accuracy, Large size of scanner, etc

60. Merits:

63. Even our two eyes have different Pattern

64. Scanner reads the Blood Vessel Pattern

65. Merits: Error rate is very less

66. Weakness: Slow, Can reveal some Medical Conditions e.g.: Hypertension

68. Most insecure form of Biometric Device

69. Professional Forgers can fool the system

70. People may not sign in identical manner

72. Two types of system:

73. Text-dependent Systems

74. Text-independent Systems

75. Demerits: Sensitive to noise, Not appropriate for large scale application

77. Intra-class Variations

78. Distinctiveness

79. Non-universality

81. Multiple Biometrics

82. Multiple Units of Same Biometric

83. Multiple Snapshots of the Same Biometric

84. Multiple Matchers

86. There are many biometric products around, based on different biometric technologies

87. Shortcomings of biometric systems due to manufacturers ignorance of security concerns lack of quality control

88. THANK YOU Any Questions???
