History of biometric systems for Access Control

Security systems have been important for many years. In times not far distant, access controls were simple gates, which were then reinforced by security guards. These security systems were effective for a while, but began to be victims of unscrupulous people who did their best to enter places, which were not authorized for criminal purposes.

Thanks to advances in technology, offering designs could achieve higher levels of security and represented a complete challenge to intruders. Thus he spent the use of conventional door locks, electronic door locks. With the adoption of this technology were able to establish access control, which was not only more effective than previous ones, but also more convenient and faster. Users of an electronic gate system had cards, which slid into a reader and had access to their workplace or important information. Furthermore, the work security guard, with these systems, it was complementary, so there were a system backup plan.

As with traditional locks, electronic gates began to present several problems. Criminals have found ways to clone or steal the cards, so it was necessary to find a new strategy, which was proof of fraud. They needed a system to ensure that only authorized people from entering a particular site, and it was impossible, that an unauthorized person would.

For a long time had been used biometrics in order to verify the identity of individuals. Thus, fingerprint analysis and reliability and respect enjoyed in the field of forensic medicine and forensic identification.

Seeing the unique, non-transferable fingerprints, experts in security solutions, decided they could use in access control. Thus, early designs were developed fingerprint biometric systems to be used as security mechanisms. These systems completely eliminated the use of keys or entry cards and based on something that could not be stolen, cloned or lost.
