BIOMETRICS

• BIOMETRICS

2

• Biometrics are automated methods of recognizing a
  person based on a physiological or behavioral
  characteristic. 

• Biometrics refers to the automatic identification
  of a person based on his/her physiological or
  behavioral characteristics

• FINGERPRINTS

• The most widely used and least expensive
  biometric technology is fingerprint scanning

• A fingerprint is made of a series of ridges and
  furrows on the surface of the finger.

• Everyone is known to have unique, immutable
  (unchangeable) fingerprints.

• This has 1/1000 misidentification rate and is
  used in medium security facilities.

• Relatively high accuracy rate.

Characteristics
5

• HAND GEOMETRY

• Every hand is unique due to its length, width,
  and thickness.

• A scanner takes 90 measurements of the hand that
  are three-dimensional - all in just one second.

• The scanner then stores all this data

• The misidentification rate is 1/700 its used in
  low security buildings.

Characteristics
6

• HANDWRITING

• A user writes a name or word on the screen of the
  PDA. Functions are provided to capture that
  handwriting, extract the relevant features, and
  compare two different samples.
• Misidentification 1/100 low security facilities.

Characteristics
7

• IRIS RECOGNITION

• Iris recognition is technology based on
  individual iris patterns.
• The iris, a thin interior eyeball membrane, is
  comprised of extremely complex patterns.
• The patterns are unique and virtually impossible
  to imitate.
• Iris patterns are stable within a year of birth,
  and remain the same for life.
• The iris has a misidentification rate of
  1/1,200,000.
• Iris recognition is used in high-security
  facilities

Characteristics
8

• RETINAL

• Based on blood vessel patterns at the back of the
  eye.
• Captured by an individual looking through a
  reticule where a low-intensity light source is
  shone through the pupil to illuminate the retina.
• Involves 360º circular scan, taking 400 readings.
• Generally used for high-end security
  applications, primarily for physical access
  control.

Characteristics
9

• Voice Recognition

• Voice recognition uses a neural net (relating to)
• program to recognize your voice.
• Works on the physical characteristics of ones
  voice.
• The user would dictate text fluently into the
  computer.
• Banks are starting to use this technology,
  instead of dialing in a pin you would speak and
  the computer would recognize your voice.
• Misidentification1/30 low security

Characteristics
10

• FACIAL RECOGNITION

• Analyzes images of the human face for the purpose
  of identifying them.
• This program takes a facial image, measures the
  characteristics such as the distance between the
  eyes, length of the nose, and the angle of the
  jaw, and create a unique file called a template.
• The technology hasnt proved reliable.
• Misidentification 1/100, low security facilities.

• Why Biometrics?

• Biometric technologies are becoming the
  foundation of an extensive array of highly secure
  identification and personal verification
  solutions.

• Biometrics is expected to be incorporated in
  solutions to provide for homeland security. This
  would include airport security, strengthening our
  borders, travel documents and preventing ID
  theft.
• Utilizing biometrics for personal
  authentification is becoming convenient and
  considerably more accurate than current methods
  (remembering pins and passwords). This is because
  biometrics links the event to a particular person
  and is convenient because there is nothing to
  carry around and remember.
