Biometric systems are those that analyze an individual characteristic such as fingerprints, facial features or eye patterns. With this in mind, many organizations have decided to adopt these systems such as access control. Just as with older methods, based on biometrics methods have also been treated deceive one way or another. That is why many scientists and companies to work in order to anticipate the criminals. In this way, spent much time and resources to find fraudulent ways, that you can use, to defeat a biometric system. This is done in order to strengthen a system in these areas and that a system of this nature is as reliable and impassable as possible. One of the attempts to pass a biometric system, fraudulently, is wearing contact lenses, that simulate the features of a registered person.

A quality system should be able to detect such fraud and that the person in question through another complementary analysis. The people who work in the development of access, fraud-proof biometric systems, analyze current systems are as effective and devise strategies that may be useful in detecting potential fraud. Consequently, significant advances have been made in eye pattern recognition systems and those who recognize the signature. Also, improvements in systems that scan fingerprints have already been made and those that scan facial features. In a fact that there is much to be done, since a biometric access system is studied with stealth by criminals, which increasingly have more advanced tools to try to make your own.

That is why that specialists must try to anticipate these bandits, to make all their attempts to overcome a biometric system in an illegal way, fruitless. Thanks to recent advances in biometric systems, it is possible to have a fraud-proof, and secure access control as attempts to use contact lenses, fake fingers or masks; they are harmless. This is due to that present systems are able to recognize the living tissue and discern whether someone is trying to circumvent them. Also scientists have been able to design systems that are friendly with the user, since each time achieved designs less invasive than in the past.
