Biometrics, systems biometric and Access Control biometrics is the science that is responsible for the identification of persons. so, biometrics examines the physiological and behavioral, qualities that make each person unique from the others. Thanks to biometrics, it is possible to establish clear differences between two people. Biometrics had its first major applications at the end of the 19th century, when it was established that fingerprints were different in every human being. At that time failed to find a method that would be used by police institutions and which is in force today. With the passage of time could find other qualities that are also unique to each individual, these are termed them biometric indicators. The best-known biometric indicators are: fingerprints, iris and retina.
However, there are other indicators such as the features of the face, the voice, how to walk, talk or write. All of these indicators have gone from being used by agencies investigative, to be employed by companies of technologies for the creation of such notorious biometric systems. Biometric systems are devices that have many utilities. In the field of security, these systems have come to be the favorite of many customers. This is because that these systems allow you to restrict access to sites or information conclusively. Thus, biometric systems are the new paradigm for access controls. Access control is a mechanism that prevents unwanted people from entering a protected location or access to private information.
First access controls were the traditional doors, then they were replaced by electronic gates which were opened by using smart cards. While these cards were a breakthrough, their effectiveness was affected by unscrupulous people, who found the way to falsify them, steal them or simply individuals who lend them to others. When you deploy an access control, supported in biometric systems, it is not possible that the access key be used by another person other than its owner. In fact, it is virtually impossible that a person uses another biometric indicators, it is not even possible to mislead a system with parts mutilated, since modern biometric devices can determine if they are considering living tissue or decaying. In addition, biometric systems, despite their achievements, are frequently monitored by security cameras, so that any anomaly will be detected by support staff. Access control can be reinforced with the help of biometric systems.
