Brief Description of biometric systems

Biometric systems use parts of the human body for identification and verification process. In order to have reliable results making use of body parts that are unique to each person, which are called biometrics.

Currently, there are several types of biometric systems, but devices that are used most frequently are those fingerprints. Other devices such as scanners or eye patterns of the face shape, not used as often because of its high price. However, these are devices that provide unparalleled results.

This technology has many uses, new security systems, because traditional methods have many limitations. It's no secret that the doors with conventional keys, could be overcome in many ways, after all anyone could clone or steal a key. Something similar happened with systems using electronic cards or passwords, since they could reach the wrong people in many ways.

Biometrics overcomes all the problems that previous systems could never defeat. Unfortunately, biometric systems have not had much press, so many people still are unaware of their existence. In addition, some people think that with these systems, civil liberties are affected and that these systems can damage health.

The first thing to understand is the difference between biometric systems that use commercial and state organizations. In the former case, they do not store biometric information of any kind. These systems analyze a property and create a sequence of numbers on that basis, to identify a person. That is, do not store images in its memory traces or eye patterns, only identify some points of these qualities, to create a sequence of personal identification. With this configuration the biometric information, people will never be at risk of being stolen or misused.

On the other hand, biometric systems are not harmful to health. The belief that the devices for analyzing eye patterns, they use laser light is unfounded. In fact, these devices use cameras not in any way affect the health of the vision. Biometric systems not only provide excellent results, but also respectful of the privacy and health of its users. That is why their use has many benefits and any negative consequences as possible.
