Investigating Facial and Fingerprint Scanning

Technologies

prepared byGroup 202.10.02

What do we want to achieve?

• Introduce Biometrics

• Explain our focus

• Introduce the technologies

• Demonstrate the business value

• Give you an outlook where biometrics are headed

What are Biometrics?

“Biometrics are automated methods of recognizing a person based on a physiological or behavioral characteristic.  Among the features measured are face, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice. “

The Industry

• Facial-scan and Finger-scan make up the majority of the market

• Both are physiological biometrics

Our focus

• Finger Scan– Optical– Ultra Sound– Chip based

• Facial Scan– "Eigenface" – Feature Analysis– Neural Network Mapping technology– Automatic Face Processing (AFP)

Finger Scan

• A fingerprint is unique & immutable

• Acquisition and storage of the image of the fingerprint

AFIS: Automatic Fingerprint Identification Systems

• Uses optical scanners and performs one-to-many operations

• Two major types– forensic– civil

Fingerprint: The Business Value

• Physical attributes are much harder to fake than identity cards

• Cannot guess a fingerprint pattern like guessing a password

• Cannot misplace fingerprints, irises or voice like misplacing an access card

• Cannot forget fingerprints like forgetting a password

Fingerprint: The Business Value

• Benefits transfer in NY, LA, and Spain• Voter registration in Jamaica • Forensic AFIS used by the FBI, state and

local police to identify criminals

Fingerprint: Limitations

• Cold finger• Dry/oily finger• High or low humidity• Angle of placement• Location of finger on platen (poorly placed

core)• Cuts to fingerprint• Manual activity that would mar or affect

fingerprints (construction, gardening)

Facial Scan

• There are various facial-scan technologies used to recognize people

• We will focus on feature analysis • One thing that they all have in common is

that they focus on areas of the face that are not easily alterable.

– cheekbone area – the upper outlines of the eye sockets– the sides of one’s mouth– etc.

Feature Analysis

Nodal Points

Facial Scan: The technology

Business Value

• Easy Acceptance

• Identify People at a Distance

• Large Scale Automatic Scanning

• Existing Huge Facial Image Database

Facial Scan: Applications

• Verification– criminal suspects– access control

• Identification– general surveillance (CCTV)

• Examples– 2001 Super Bowl in Tampa– Virginia Beach CCTV network– Police Dept. in many US states and cities

Limitations

• Not very accurate

• Changes in Facial Features– surgeries, aging, etc.

• High ambient requirement

• Disguise

• Privacy issues

Conclusions and Outlook

Biometrics can add significant business value...

...but user perceptions of biometric technology are an essential element in their success.

More and more legislation that addresses biometrics is being passed:

– USA Patriot Act (signed in October 2001)– Aviation and Transportation Security Act (signed in

November 2001)– Enhanced Border Security and Visa Reform Act (signed

in May 2002)
