TYPES OF BIOMETRICS (Based on Chapter 3&4) Chang Jia Sep 12th, 2005 Guide to Biometrics

In General ,[object Object],[object Object],Examples: face, fingerprint, hand geometry and iris recognition Examples: signature and voice Biometrics can be sorted into two classes :

Biometric Identifiers ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

1. Fingerprint Recognition ,[object Object]

[object Object],[object Object],[object Object],[object Object],[object Object],Acquisition Devices ,[object Object],[object Object]

Applications Identification, or 1-to-Many: identifies a person from the entire enrolled population. Authentication, or 1-to-1: matches a person's claimed identity to his/her biometric and one or more other security technologies (password, PIN, Token). (See http://www.biometrics.dod.mil/bio101/index.aspx )

Minutiae ,[object Object],[object Object],Minutiae Finger Image + Minutiae Finger Image

Fingerprint scanning ( Minutiae based approach )

Matching Approaches ,[object Object],[object Object],Two basic classes of matching techniques: Combining the above two techniques: ,[object Object],[object Object],Extracts features and develop representations from these features

2. Face Recognition ,[object Object],[object Object]

4. Iris recognition ,[object Object],[object Object],[object Object]

Applications ,[object Object],[object Object],Heathrow Airport (London) - Iris

5. Hand geometry ,[object Object],[object Object]

How does it work ,[object Object],( See Jain et al. A Prototype Hand Geometry-based Verification System )

Applications BenGurion Airport - Hand Geometry INSPASS - Hand Geometry see INS Passenger Accelerated Service System

6. Signature Verification ,[object Object],[object Object],[object Object],[object Object]

Biometrics in Early Stages Body odor Lip motion Skin reflection Ear recognition Keystroke Gait Thermograms Retina recognition DNA

I. DNA ,[object Object],[object Object],[object Object],[object Object],[object Object]

Comparison Chart Uses templates or feature extraction Does a comparison of actual samples Done in real-time; “lights-out” automated process Not done in real-time; not all stages of comparison are automated Uses an impression, image, or recording Requires an actual physical sample Conventional Biometrics DNA

II. Retina recognition ,[object Object],[object Object],[object Object]

III. Thermograms ,[object Object],[object Object],[object Object]

IV. Gait ,[object Object],[object Object],Examples for measurements (from Georgia Institute of Technology )

V. Keystroke ,[object Object],[object Object],[object Object]

VI. Ear recognition ,[object Object],[object Object],[object Object],[object Object]

VII. Skin reflection ,[object Object],[object Object]

VIII. Lip motion ,[object Object],[object Object],[object Object]

IX. Body odor ,[object Object],[object Object],Prometheus (Alpha Mos) , an example of electronic nose Schematic Diagram of Artificial nose ,[object Object]

The Future ,[object Object],[object Object],[object Object],Challenges: Are biometric technologies ready for what is being expected of them?
