  1. BIOMETRICS: FACIAL RECOGNITION TECHNOLOGY By Matthew Willert PUAD 620

  2. OUTLINE • WHAT IS BIOMETRICS? • WHAT IS FACIAL RECOGNITION TECHNOLOGY? • CONTROVERSY • MY OPINION OF THIS TECHNOLOGY • QUESTIONS????????

  3. WHAT IS BIOMETRICS? BIOMETRICS – any automatically measurable, robust and distinctive physical characteristic or personal trait that can be used to identify an individual or verify the claimed identity of an individual.

  4. TWO MAIN USES 1) IDENTFICATION -figure out “Who is X?” -accomplished by system performing a “one-to-many” search 2) VERIFICATION -answer the question “Is this X?” -accomplished by the system performing a “one-to-one” search

  5. TYPES OF BIOMETRICS Iris Scanning -measures the iris patter in the colored part of the eye Retinal Scan -measures the blood vessel patterns in the back of the eye

  6. TYPES OF BIOMETRICS Voice Recognition -measures the vocal characteristics of a person using a specific phrase Finger Printing -measures the unique pattern of lines on a persons finger

  7. FACIAL RECOGNITION Facial recognition is a form of computer vision that uses faces to attempt to identify a person or verify a person’s claimed identity. Regardless of specific method used, the facial recognition is accomplished in a five step process.

  8. FIVE STEP PROCESS (STEP 1) ACQUIRING THE IMAGE OF AN INDIVIDUALS FACE 2 WAYS TO AQUIRE IMAGE 1)Digitally scan an existing photograph 2)Acquire a live picture of a subject

  9. FIVE STEP PROCESS (STEP 2) LOCATE IMAGE OF FACE -software is used to locate the faces in the image that has been obtained

  10. FIVE STEP PROCESS (STEP 2)

  11. FIVE STEP PROCESS (STEP 3) ANALYSIS OF FACIAL IMAGE -software measures face according to is peaks and valleys (nodal points) -focuses on the inner region of the face known as the “golden triangle” -nodal points are used to make a face print

  12. FIVE STEP PROCESS (STEP 4) COMPARISON -the face print created by the software is compared to all face prints the system has stored in its database.

  13. FIVE STEP PROCESS (STEP 5) MATCH OR NO MATCH -software decides whether or not any comparisons from step 4 are close enough to declare a possible match

  14. FINAL STEP THE HUMAN OPERATOR

  15. CONTROVERSY FALSE POSITIVES -FACIAL RECOGNITION VENDOR TEST 2000 -PALM BEACH INTERNATIONAL AIRPORT -FACIAL RECOGNITION VENDOR TEST 2002

  16. CONTROVERSY VIOLATION OF CONTITUTION RIGHT AGAINST UNREASONABLE SEARCH? United States v. Dionisio, 410 U.S. 1, 14 (1973) -person does not have a reasonable expectation of privacy of those physical characteristics that are constantly exposed to the public such as one’s facial features, voice and handwriting

  17. CONTROVERSY THE BORDER EXCEPTION -the fourth amendment recognizes the longstanding right of the sovereign to protect itself by stopping and examining persons and property crossing into this country

  18. MY THOUGHTS ON FACIAL RECOGNITION TECHNOLGY

  19. REVIEW • WHAT IS BIOMETRIC? • WHAT IS FACIAL RECOGNTION TECHNOLOGY? • CONTROVERSY • MY OPINION

  20. QUESTIONS??????
