2. WHat Is Biometrics?
biometrics -- technology that identifies you based on your
physical or behavioral traits -- for added security.

3. How It Works
Enrollment- 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 information
3. Software- analyzes the physical characteristic, translates it
to code and performs the comparison

5. Handwriting
1.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 different
2. 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 eye
2. 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 picture
3. 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 disabilities
3. Interoperability- in emergency situations, retrieving data
is more difficult
