As we all know, new technologies are created with to goal to render our lives easier and better. With all new technologies, perfection is something that is far obtainable because we will eventually find some flaws in it. As for the Iris recognition technology, an emerging biometric device, we have already found a few problems associated with it. These include its difficulty in performing the test at a distance larger than a few meters (1). Although no physical contact is needed for the recognition of the individual, the distance between the camera and the person’s iris cannot go beyond a certain limit.
Also, in situations where the person to be identified does not cooperate by holding his head still and looking toward the camera at the proper distance and position, recognition of the iris may be erroneous and as such, identification of the person will as well be affected (2). Matching of the person’s iris to the database may be rendered difficult or inaccurate. Similar to other photographic biometric technologies, Iris recognition is still susceptible to poor image quality.
Because this technology is still fairly new, the costs of installation and recognition devices may be very expensive and as such, not all industrial fields will have the means to upgrade to these new technologies (2). Another problem related to Iris recognition involves people who are blind but have eyes and are unable to position themselves properly in front of the device for identity authentication (3). As for people who lacks eyes, this technology may not be employed and thus, these people must rely on other technologies such as finger print recognition when using ATM or traveling (3).
