Chart


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


Characteristics


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


Relatively high accuracy rate.


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


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

Characteristics


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 it’s used in low security
buildings.


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


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


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 360
º circular scan, taking 400 readings.


Generally used for high
-
end security applications, primarily for physical
access control.

Characteristics


Voice recognition uses a neural net (relating to)

program to recognize your voice.


Works on the physical characteristics of one’s 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


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 hasn’t proved reliable.


Misidentification 1/100, low security facilities.

By the year 2004 biometrics will increase 100%.



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.
