its a identification system used to identify individuals....its the most reliable technology

2.  The retina is the light-sensitive tissue lining the back of our eye.
 The iris is a thin, circular structure in the eye, responsible for
controlling the diameter and size of the pupil and thus the amount of
light reaching the retina. The color of the iris gives the eye its color.
 The pupil is a hole located in the center of the iris of the eye that
allows light to enter the retina

3.  Identifies individuals by retinal blood vessel pattern
 Unique for each individual (including twins)
 Patterns do not change over an individual’s lifetime with the
exception of some degenerative eye diseases or cases of severe
head trauma.
 Due to its unique and unchanging nature,retina is the most precise
and reliable biometric.
 Identifying the iris and converting it to mathematical code.

4. Two types of methods that are used by iris identification systems :
ACTIVE
PASSIVE

5.  Retinal scan is used to map the unique patterns of a person’s retina.
 Blood vessels within retina absorb light readily than the surrounding
tissue and are easily identified with appropriate lightning.
 Retinal scan is performed by casting low intensity infrared light into
persons eye as they look through the scanner’s eyepiece.

6.  Used in prisons and for ATM identity verification.
 Some states require compulsory retinal scans for truck and bus
drivers.The results obtained are used to stop unskilled drivers from
obtaining licenses in various states inorder to hide their driving
records.

7.  Accuracy
 Stability
 Reliability
 Fraud Resistant
 Speedy Results
 Relatively small template size

8.  Vulnerable to degenerative diseases which may alter the retinal
patterns.
 High equipment cost.
 Poor lightning can affect results.
 Not user friendly.
 Scanning procedure is highly invasive and relies on user
cooperation.
 Not enough funding from government and private sectors.

9.  Iris identification technology is used in Japan to identify racehorses.
 Iris scanners used in the Winter Olympics to identify biathlon
participants before granting them access to rifles.

10.  Experts predict that the “killer application” for iris identification
technology will be ecommerce.
 Legal tender in ecommerce age will be digital signatures combined
with coded image of person’s iris.
