Biometric Systems Analysis

Biometric systems: Analysis of Retina in a study of retina Access Control is one of the oldest biometric analysis. Already more than 70 years ago failed to establish that the arrangement of blood vessels in the eyes, was different in every human being. With the passing of the years, this idea took force, making it possible that patented the first reader of retina, which then went on the market at the beginning of the 1980s. A record of the retina, analyzes not only this part of the eye, but it also analyzes the layer of blood vessels in the back of the same. This is done using a low-intensity light source and an optical reader, which detects way accurate eye patterns. To ensure that a person subject to this type of analysis, it is necessary to remove his glasses, if the usa, put your eyes near the appliance and look towards a particular point. This point is usually a green flicker, which should see with attention for a few seconds, so that the mechanism can do their work.

By the general the process of capturing and matching of patterns takes about 10 seconds, so the system is not only effective, but also quick. A retinal scanner is a good option as access control system, because copying a retina, with all its elements, is an impossible task. On the other hand, not is you can trick the system with a retina of a dead person, because their deterioration is very fast and because there are systems that know are when dealing with living tissue or not. Such is the effectiveness of these devices, as many areas of restricted access such as military bases, nuclear power plants, embassies, laboratories, security agencies and other large organizations; make use of them. These places have been found on retina readers a system of access control inviolable and above all fast. The reason why these organizations have access to these readers is because they are the only ones that can afford to purchase this technology, since the prices of these devices are somewhat high. Biometric locks may be a good strategy, to improve the security in places like businesses, homes, schools, etc. These locks are based on biometric systems and only open when supplied an imprint, previously registered.
