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

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

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

9
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

10
FIVE STEP PROCESS (STEP 2)

• LOCATE IMAGE OF FACE
• -software is used to locate the faces in the
  image that has been obtained

11
FIVE STEP PROCESS (STEP 2)
12
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

13
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.

14
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

15
FINAL STEP

• THE HUMAN OPERATOR

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
  ones facial features, voice and handwriting

19
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
