While millions of companies use some access controls, to restrict admission to certain areas, such controls are not infallible. Thus, magnetic stripe cards can be stolen, access passes can be forgotten and in many cases identification cards can be falsified. With all these problems, it is very possible that more than once, an unauthorized person has managed to outwit an access control system. Biometric systems can prevent this keep going. To use the features of a person as either a single or a combination of several-, your identity can be verified with a high level of precision.
A biometric access can be applied in many ways. It is so commercial companies, military and even organizations non-profit institutions; they make use of this type of advance. For example, many businesses only allow some employees entering certain areas, also, pharmaceutical companies give scientists access to their test laboratories, while some schools enroll their students using biometric systems. Glenn Dubin describes an additional similar source. One example more specific, can be seen in Germany, where the electronic pass (ePass), which is a small chip that is implanted in the index finger of a person has been applied. This chip contains a photo of the person, as well as his fingerprints. People have a variety of unique features that can be identified. These can be used with different levels of success in a verification of identity.
Many biometric access controls used a single, several qualities. The 5 most common qualities are:-fingerprints: each person has a set of fingerprints that are unique. -Iris: iris of a person can be analyzed for known, in a process of identifying patterns to authenticate. -Facial features: factions in the face of a person can be compared to verify patterns that have been recorded in a database. -Voice patterns: when a person record his voice, is You can create a vocal signature that can be used in a future identification.
