3. The study of methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits
In computing terms biometrics relates to the ability of a computer to uniquely identity humans based on physical or behavioral traits
They are generally thought to be the most secure method of authenticating a person
What is Biometrics?

4. How Biometric Devices Work
1. Initial scanning of individual’s identity
2. Information is saved as electronic copy in a database
3. When login occurs, the individual’s identity is scanned again
4. The data is compared to the saved copy in the database
5. The user is authenticated
How Biometric Devices Work

5. Goals Of Biometric Devices
All of the following criteria should be met in order create a proper biometric device
Universality – Does Each Person Have It?
Uniqueness – Is It Unique Per individual?
Permanence – Does It Have Lasting Power?
Collectability – Is It Measured Easily?
Performance – Is The Device Accurate, Fast?
Goals Of Biometric Devices

6. Measuring Performance
When measuring biometric performance the following are the primary attributes used :
Accuracy
Reliability(Causes of Errors)
False Positives
False Negatives
Ease Of Use
Cost
Measuring Performance

7. Measuring Performance
Accuracy – How well the device can tell different users apart
Reliability – How often a device give an accurate reading of a user.
Many factors contribute to a false reading
False Positives – How easy a fake user can impersonate a real user
False Negatives – How often a real user is denied access
Measuring Performance

8. Measuring Performance
Ease Of Use – The ability for non-technical user’s to use the system.
Cost – The cost, initial and reoccurring associated with maintaining a biometric device or system of devices
Measuring Performance

9. Biometrics can identity a unique person using the following methods:
Physiological Trait Identification
Behavioral Trait Identification
Types Of Biometrics

10. Physiological Feature Based Biometric Devices
These type of devices use traits of the body to identify a person, and include:
Fingerprints
Face Recognition
Iris Recognition
Retinal Recognition
Hand Geometry
Physiological Feature Based Biometric Devices

11. Examples Of Physiological Based Devices
Fingerprint Scanner
Hand Geometry Scanner
Examples Of Physiological Based Devices

12. Behavioral Feature Based Biometric Devices
These type of devices use unique behavioral characteristics to identify a person, and include:
Keystrokes
Voice (could also be classified as a physiological characteristic, however recently it is more focused on how one speaks to uniquely identify, thus making it behavioral based)
Behavioral Feature Based Biometric Devices

13. Performance Comparisons

14. Uses Of Biometrics Protect data and other sensitive material
Use in law enforcement and surveillance
Employee monitoring and record keeping
Protect automobile and other personal objects.
In The Future:
Identifying people without physical ID
Medical Purposes
Passports
