BIOMETRICS: FACIAL RECOGNITION TECHNOLOGY By Matthew Willert PUAD 620

OUTLINE:

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

WHAT IS BIOMETRICS? :

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.

TWO MAIN USES:

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

TYPES OF BIOMETRICS:

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

TYPES OF BIOMETRICS:

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

FACIAL RECOGNITION:

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.

FIVE STEP PROCESS (STEP 1):

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

FIVE STEP PROCESS (STEP 2):

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

FIVE STEP PROCESS (STEP 2):

FIVE STEP PROCESS (STEP 2)

FIVE STEP PROCESS (STEP 3):

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

FIVE STEP PROCESS (STEP 4):

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.

FIVE STEP PROCESS (STEP 5):

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

FINAL STEP:

FINAL STEP THE HUMAN OPERATOR

CONTROVERSY:

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

CONTROVERSY:

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

CONTROVERSY:

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
