Biometric Systems for Access Control Biometrics Iris

Iris biometrics is based on the analysis of the characteristics of the colored part of eye and located around the pupil, in order to verify the identity of one or more individuals. Currently, there are several devices that make an analysis as part of an iris as access control.

Biometric systems for the analysis of the iris, are very effective, but should be improved in several respects. On the one hand, readers should be improved to obtain better quality images. Moreover, the industry of biometric solutions is designed to create designs that are becoming more independent and less invasive. This means that it seeks to create devices, which operate without continuous human supervision and that are comfortable for people who have to use.

Devices for the analysis of iris have faced many difficulties. Thus, factors such as pupil dilation, and contact lenses over the years in the eyes have been some of the problems mentioned. The first systems that were built did not account for the dilation of the pupil and their designers completely disregarded the consequences of aging. As for contact lenses, this was a problem that designers quickly resolved.

The problem with dilated pupils is that the sample stored in the memory access system may be different from the counter sample, which is the time it takes to verify the identity of a person. That is why iris biometrics works best when the pupil is not in a state of expansion, but it is difficult to control eye movements. With the aging of the eye passes something, which was also a problem to solve. To solve these problems, samples of the databases are updated frequently, which helped to avoid errors, but it was tedious for users.

With recent advances in biometric systems will soon be possible to create devices that make iris analysis accurately, but their results are affected by the dilation of the pupil or the elderly. In addition, devices that they believe will create high quality images, which operate independently and do not represent any inconvenience to its users, making it ideal in a modern access control.
