There are three main types of authentication: something you know, something you have, and something you are. Biometrics uses biological and behavioral characteristics to identify individuals, such as fingerprints, iris patterns, voice, gait, and signatures. Some common biometric technologies are fingerprint, face, iris, vein, voice, and signature recognition. Biometrics can be used for applications like access control, time/attendance tracking, airports, ATMs, and more. While biometrics provide security benefits, they also have disadvantages like cost, accuracy issues, and privacy concerns. The field continues to evolve as costs decrease and convenience increases.

1. Biometrics Technology

2. three main types of authentication available today are:something you know, like a password, PIN, or code.

3. something you have, like a swipe card, smart card, token, or key.

4. something you are, which is biometrics. What is a biometric?BiometricsIs the term given to the use of biological traits OR behavioral characteristics to identify an individual.

5. CharacteristicsThe common Physical characteristics are:Fingerprint FaceRetina Iris Vein pattern, and Hand and finger geometry

6. CharacteristicsBehavioral characteristics are:Keystroke dynamics Voice Gait, and Signature dynamics

7. The Biometric importanceThe security is needed in every place. Alleviate the existing problems, Like those which can be taken, stolen, borrowed or even forgotten.

8. The Biometric importance (Cont.)Improves convenience, security, and privacy.The first and most critical link in the security chain. presented to counteract security threats.

9. Biometrics HistoryThe term "biometrics" is derived from the Greek words (life)and metric means(to measure).bio which means

10. 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.

11. 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.

12. Biometrics History (Cont.)After this, finger printing, which was developed by Richard Edward Henry of Scotland Yard.

14. Physical Characteristics

15. 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.

16. Fingerprint Recognition steps:Database

17. Face Recognition:Face recognition uses the visible physical structure of the face and analyses the spatial geometry of distinguishing features in it to identify an individual.

18. Face recognition process:Extraction of face featuresInput face imageExtraction of face imagePositiveDatabasenegative

19. Iris Identification:The iris is the colored ring of textured tissue that surrounds the pupil of the eye.

20. Iris Identification Steps:Input of face imageRecognition of iris patternDetection of eye regionsPut iris in focusacceptDatabasereject

21. 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:The output pictureGenerate veins structureInput of palm pictureDatabasematchNot match

22. Behavioral Characteristics

23. Voice Recognition:Voice Recognition: is the Identification using the acoustic features of speech that have been found to differ between individuals.

24. Voice Identification SystemConstruct voice reference templateDatabase

25. Signature Identification:Signature identification: is the analyses of the way a user signs his or her name.The process used by a biometric system to verify a signature is called dynamic signature verification (DSV).

26. Signature Verification Process (Cont.)the angle at which the pen is held,

27. the number of times the pen is lifted,

28. the time it takes to write the entire signature,Biometric traitthe pressure exerted by the person while signing,

29. the variations in the speed with which different parts of the signature are written. Signature Verification ProcessProfileDatabase

32. Applications of Biometric Access control :Disney World (fingerprint scanner).

33. Child day care centers ( hand geometry systems )Applications of Biometric (Cont.)Time and attendance management: Hospitals (hand geometry systems) Other Applications Airports:

34. Heathrow airport (iris recognition)ATMs:(face recognition)Other Applications (Cont.)Pc access:GM and Hertz (voice identification technology) to protect their computer facilities.

35. Fujitsu has developed a mouse that can verify a person's identity by recognizing his pattern of blood veins. Other Applications (Cont.)Prisons: Fujitsu has developed a mouse that can verify a person's identity by recognizing his pattern of blood veins.

36. Advantages of biometricsUniquenessUniversalityPermanenceMeasurabilityUser friendlinessAccuracyComfort

37. Disadvantages of Biometricscostly.Facial imaging can also hinder accurate identifications.Missing body part problem.

38. Disadvantages of Biometrics (Cont.)False acceptances and rejections.The amount of comfort.The scanning of eye is fearful.The nervousness that people feel about the scanners identification.

39. Future ProspectsBiometry is one of the most promising and life-altering technologies in existence today. It is all set to change the way we live in the future.Some of the emerging biometrics technologies in the near future are:Ear shape identification.Body odor identification.Body salinity identification.EEG FingerprintDNA matching

40. ConclusionNot perfect yet.Successful applications.Decreasing costs and increasing convenience. Increasing both privacy and identity security. The field of biometrics is evolving. Benefit from this technology .
