Among the different biometric modalities like fingerprint, finger vein, palm vein, facial, etc. retinal scan is one of the most reliable ones. Retinal security scan has proven its capability in implementing reliable biometric security protocols in various high-risk sectors like border patrol and aviation. Retinal scan authentication is a complex mathematical pattern. It is a technique that identifies the unique eye patterns of an individual.
Retinal scanning is based on the fine capillary network that provides oxygen and nutrients to the retina. These blood vessels absorb light and can easily be visualized with appropriate lighting. It requires a close distance between the eyes and a scanner. The appropriate position of eyes toward the scanner is also necessary. And, there must be no eye movement such as blink or glance.
The characteristics of the retinal scan are significantly unique for each and can be recognized from placing an eye close to the scanner. That’s why it is much more challenging to fool as compared to other biometric techniques, false acceptance rate and the false rejection rate is remarkably low. In such a way, it has become the most secure authentication technology which has been successfully used in various fields.
This technology inspects the complex mathematical patterns of an individual’s eye which are significantly unique for each. A comprehensive study on biometric authentication found that the false rejection rate of retinal security scanning is only 1.8% which is the lowest among all other biometric security methods.
Even with this low rate of rejection, there are some things that can effect this technology. Although the pattern of capillary blood vessels of the retina stay the same, some conditions like diabetes, glaucoma, and cataracts can change this pattern. This makes retinal scan technology less suitable for use in offices or any other place.
Retinal security scanning is a smart security system as compared to others and it is pretty accurate to use in your organization.
