3D biometrics Passwords for safety .pptx

Its all about The passwords that are used to secure our phone or laptop etc.... many biometrics we set in our phone it is all about it.

1. 3D passwords Biometrics

2. What is biometrics? Biometrics is the science of verifying and establishing the identity of an individual through physiological features or behavioral traits. Characteristics: Physiological: - Fingerprint - Face - Iris - Hand Geometry Behavioral: - Voice - Keyboard strokes - Signature

3. General biometrics System Database Biometric Sensor Feature Extraction Biometric Sensor Feature Extraction Matching ID : 8809 Authentication Enrollment Result

4. Different types of biometrics FINGERPRINT RECOGNITION FACE RECOGNITION IRIS RECOGNITION HAND GEOMETRY VOICE SCAN KEYSTROKE SCAN SIGNATURE SCAN

5. Fingerprint recognition Measures unique characteristics in a fingerprint (minutiae) Crossover Core Bifurcations Ridge ending Island Delta Pore Advantages: multiple fingers, large database, proven technology Disadvantages: skin worn out due to age

6. Face recognition Uses off-the-shelf camera to measure the following facial features: Distance between the eyes Distance between the eyes and nose Angle of a cheek Slope of the nose Facial Temperatures Advantages: No contact required, cameras are common Disadvantages: Face can be obstructed, sensitive to changes in age, depends upon lighting and camera angle

7. Hotel Check-in using Biometrics Example

8. Iris recognition Measures unique characteristics of the Iris like ridges, furrows, striations Advantages: Iris is stable over lifetime, no contact is needed Disadvantages: Difficult for people having eye disorders, some people may find this technique somewhat obtrusive.

9. Hand geometry Measures the top and sides of the hand, not the palm, contrary to the popular belief Measures the finger lengths, widths, curves Advantages: Easy to capture, widely used for physical access, stable over lifetime Disadvantages: Not sufficiently distinctive over a large population, so not very accurate

10. Voice scan Measures the sound wave Factors: pitch, intensity, quality and durations of human speech. user talks to a microphone a passphrase. voice print is compared to a previous one Advantages: Easy to implement wherever there is a telephone in use Disadvantages: High variability in an individual’s voice, background noise

11. Keystroke scan Keystroke scan: Measures the time between strokes and duration of key pressed. Most commonly used in systems where keyboard is already being used.

12. Signature scan Signature scan: Measures speed, pressure, stroke order an image of signature. Non-repudiation Mainly used for verification However forgers could forge it with some training

13. Uses and applications of biometrics Government and law enforcement Forensic applications Commercial applications Passport control Border Control Access control to government systems Criminal investigations Corpse identification Missing person identification

14. Commercial applications Computer login to different systems Secure banking Employee verification Electronic payment ATM Record protection
