IRIS
- Iris recognition technology uses an infrared illumination to allow a camera to create images of the intricate structure of the iris, which is then stored as a digital map that can be compared to an iris presented at the identification port to provide positive identification.
- It is form of biometric identification, like fingerprinting.
- Like the fingerprint, the pattern in the iris is randomly formed during gestation, so no two individuals have identical iris patterns.
RETINAL
- The measuring of blood vessel patterns from the back of an eye is considered to be retinal scanning.
- However, retinal scanning is not yet readily available because some find this biometric system to be disturbing, since it involves the person to stand very still while a light source is shined in their eye.
- Replicating the retina is impossible because the blood vessels that are present at the back of the eye form a unique pattern. The retina scan takes about 15 sec to complete and requires careful concentration.
