Retina Scanner

Retinal scanning is a process where a low level light source and a sensor can scan the pattern of blood vessels at the back of the retina.

Retina scans are so accurate in discovering identity that the identity error rate is estimated to be only one in every million. although finger print scanners are the most popular form of human recognition (Biometrics) it has a high rate of failure, with a chance of it happening every 1 in 500 times, the other popular form of biometrics is the iris scanner which has an error rate of approximately 1 in 131,000.

Traditionally used to block physical gateways, such as those guarding the cores of power plants or military installations, the retinal scan has been employed in recent times to safeguard critical computers and their data. The retinal scan retails for as low as $220, making it affordable to anyone wanting to maintain high levels of security.

The only problem with the retinal scanner at the present, is that people with diseases such as chicken pox, leukemia and sickle cell anemia effect the eyes and increase/decrease retinal blood vessal size, resulting in the retinal scanner being unable to identify the effected.

Advantages:


 * The most accurate form of human recognition.
 * Impossible for someone to fake anyone else's retina.
 * Quick results, only takes a few seconds to scan someone's retina.

Disadvantages:


 * User has to put their face next to the machine and focus on a retina scanner for 3 seconds
 * Slightly more expensive then basic fingerprint reader
 * The scan is effected by some diseases.
 * High equipment costs.

The Retina Scanner is not the same as the Iris scanner. The Retina is the inside of the eye and is unique to every person. It is the wall at the back of the eye. The Iris is the coloured part of the eye that is around the pupil and this is also unique to the individual and the iris scanner is different to the retina scanner because the iris scanner scans the iris. Therefore the retina scanner scans the retina.
