What are Iris biometrics?
Biometry practice creates an identification system based on biological features for each person. The pattern of each person's iris is unique, allowing Iris detection one of the smartest biometric technologies available. Iris Biometrics is a method of identifying biometrics performed by taking pictures of the eye of a high -resolution person. The technology uses the camera to create an eye template, noticing the reflection of the cornea.
The process relies on the transformation of the Iris image to a mathematical algorithm. Every time the eye of the person is scanned, it is compared with mathematical data from the first scanning. Part of the eye is always covered with a lid. The mathematical equation takes into account the eyelids in adapting a person with his scanning by deducting areas covered with lids from the data. This technology can be used to identify one person in the crowd or adapt one person with their own identification data.
Iris scanning uses to protect sensitive information and allow access only for a particular individuale. In some places it is also used as a means of national security. Iris biometry is considered especially reliable. As with any identification method, there is still a chance for a human error, although it is less than other technologies, because the calculations for iris identification are performed by a computer.
Compared to fingerprints, another method of biometric authentication has several advantages. Iris is an internal organ, protected from damage to the environment. Makeup iris is determined during pregnancy. Although certain health conditions and surgical procedures can affect the color and shape of the iris, the texture that is measured by technology remains stable. Biometric devices using IRIS scanning have been identified by the same person for more than 30 years. Iris biometry is considered to be more reliable than the popular method of retinal scanning because the retina is subject tochanges with age.
On the other hand, Iris biometry is still considered a relatively new technology. For example, it has no length of time associated with fingerprints. It is difficult to do remotely and a person who does not hold his head or does not look into the camera can be incorrectly identified. Poor image quality and software failure are two factors that can adversely affect IRIS biometry technologies.
