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.
- 13. Biometrics Processnew biometric sample is requested.NoQuality Sufficient?Signal Processing, Feature Extraction, RepresentationBiometricData CollectionTransmissionYesGenerate TemplateDatabaseTemplate MatchDecisionConfidence?YesNo
- 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.
- 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
- 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
- 30. Movies to Real World
- 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 .
