Transcript

  • 1. BioMetrics By Sam Stothoff
  • 2. WHat Is Biometrics?biometrics -- technology that identifies you based on your physical or behavioral traits -- for added security.
  • 3. How It WorksEnrollment- Records information, takes your physical shape Storage- Physical trait is transferred into code and stored Comparison- The next time the system is used, the new trait is compared to the old one
  • 4. Components of Biometrics 1. Sensor- detects the physical characteristic 2. Computer- reads and stores the information3. Software- analyzes the physical characteristic, translates it to code and performs the comparison
  • 5. Handwriting1.Looks at the speed, pressure applied and sequence of what you write 2. Hard to duplicate
  • 6. Hand And finger geometry 1.Authenticates users, doesn’t identify them 2. Uses a digital camera and a light 3. Usually in lower end places, cheaper
  • 7. Voiceprints 1. Each voice is different2. Uses spectrograms(above) to analyze voice with frequency vertically and time horizontally
  • 8. Iris Scanning 1. Uses a camera to take a picture of your eye2. Software locates the center of the pupil, edge of the pupil, edge of the iris, and the eyebrows and eyelashes 3.Very secure, every eye is unique
  • 9. Vein geometry 1. Veins are unique for everyone 2. Uses an infrared light to take a picture3. Veins absorb the light and look black in the picture
  • 10. Problems 1. Over reliance- the perception that Biometrics is foolproof 2. Accessibility- the systems cannot adapt to disabilities3. Interoperability- in emergency situations, retrieving data is more difficult
