Iris Biometrics relies on the analysis of the characteristics of the region colored eye and located around the pupil, for the purpose of verifying the identity of one or more individuals. Currently, there are several devices that make an analysis of the iris as part of a for access control. Biometric systems, for analysis of the iris, are very effective, but must be improved in several aspects. On the one hand, readers must be improved to obtain better quality images. In addition, industry biometric solutions aims to create designs that are increasingly more independent and less invasive. This means that it seeks to create devices, which operate without continuous human surveillance and which are comfortable for the people who have them to use.
For iris scanning devices have faced many difficulties. In this way, factors such as the dilation of the pupil, the passage of the years in the eyes and contact lenses; they have been some of the problems mentioned. The first systems that were built were not into account the dilation of the pupil and their designers rejected completely the consequences of aging. Regarding contact lenses, this was a problem that designers resolved quickly. The problem with the dilation of the pupil is that the saved sample in memory of an access system, may be different to reference the of the sample, which is which is taken at the time of verifying the identity of a person. That is why the iris biometrics gives best results when the pupil is not in a State of expansion, but is difficult to control eye movements.
With aging eyes goes something like, which was also a problem to solve. To address these drawbacks, samples of databases were updated frequently, which helped to avoid mistakes, but something tedious was for users. With recent advances in biometric systems, very soon it will be possible to create devices that will make an analysis of iris in a manner accurate, unless its results are affected by the dilation of the pupil or old age. In addition, also devices that create high quality images, which operate independently and representing no discomfort for your users, will be created making it ideal in a modern access control.
