Computer Aided Identification

• The Future of Security

2
Introduction

• Why do you need New Computer Security?
• Computers are integral part of society
• E-Mail
• E-Commerce
• Online Banking / Bill Pay
• Your Personal Information is at Risk!

Computer Aided Identification is the Cure!

• Biometric Authentication
• Study of Human Identification
• Physical Traits
• Behavioral Traits

3
Biometric Authentication

• Iris Scan
• Camera Scans Eye
• Both irises are scanned
• Recognizes small details of each eye
• Compares to Saved Images
• Matches up details of each iris
• Recognizes as a Success or Failure

4
Why Iris Technology

• Easy to deal with everyone
• Very few people have one or less eyes
• Irises are the same from one year old and remain
  constant
• Not considered Intrusive
• No contact with the skin is made
• Can be operated without people to access the
  program
• Can be combined with motion sensors

5
Uses of Iris Technology

• Today
• Used in transportation, hospitals, and government
• Used in Big Business as a means of security
• Future
• To be used with wireless technology to prevent
  fraud during any economical transactions
• To be used as a key

6
Iris Technology

• Pros
• More accurate than fingerprinting
• Stable over many years
• Very difficult to fake
• Cons
• Requires full cooperation of the subject
• Once someone makes a fake your security is
  compromised

7
Biometric Authentication

• Finger Print Scan
• Optical Scanner
• Obtains image of finger print
• Uses light to compare to pre-scanned images
• Capacitance Scanner
• Scans using electricity to determine the ridges
  and valleys of fingerprint
• Compares to pre-scanned input from fingerprint

8
Optical Scan

• Uses CCD (Charge Coupled Device)
• Same CCD used in Digital Cameras
• Generates a signal from light
• Signal is reversed and an inverted image appears
• Light areas represent valleys and dark areas
  represent ridges
• Error checks for darkness of scan and image
  definition

9
Capacitance Scan

• Uses semiconductors to check for the ridges and
  valleys in fingerprints
• The capacitance is varied by the distance the
  finger is away from the semiconductor plates
• Finger ridges will result in different voltages
  than finger valleys
• The processor puts together a picture from the
  readout
• Requires real fingerprint type to match voltage

10
Finger Print Scan

• Pros
• Cannot Forget Finger Print
• Much Harder to Fake
• Cannot Misplace Finger Print
• Cons
• Optical Scanner cannot tell between a finger and
  a picture of a finger
• Capacitance Scanner can be fooled with a mold of
  the desired finger

11
Facial Recognition Scan

• Uses Digital Photos
• Compares live image to the facial database
  picture
• An algorithm is used to determine lines on the
  face and different facial features
• If the algorithm passes then the person is
  identified

12
Uses of Facial Recognition

• Casinos
• Use facial recognition to catch known card
  counters and thieves
• Police Departments
• Use facial recognition on pictures of employees
  at different locations to catch criminals
• Border Patrol
• Use on passports and ID cards to ensure security

13
Issues and Concerns

• With Biometrics becoming available, individuals
  could
• Plant DNA at the scene of a crime
• Fool a fingerprint detector with a piece of tape
• Fool an iris detector with a picture of an eye
• Break into the system and make a fail code a
  pass code

14
Uses and Initiatives

• Canada
• Uses digital images in passports that are stored
  on a chip that is built into the passport and
  scanned at borders
• United States
• Government is using all the types listed in this
  presentation as well as others not available on
  the market

15
Conclusion

• Different Computer Aided Identifications
• Iris Scan
• Face Scan
• Finger Print Scan
• Issues and Concerns
• Criminal Acts
• Identity Theft
• Uses
• Present and Future
