Systems Biometric

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. 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. -Hand geometry: hands, despite seem equal, are different in each person, due to its curves, its thickness and the position of the joints if it seeks a totally reliable access control, it is best go to biometric systems. These systems could eliminate all the problems, that the conventional mechanisms of access could never overcome.

Prime Minister

U.S. chooses its Presidents with a model that is halfway which governs South and North of its borders. Latin America has been taking the French system in which the President should be elected with more than 50% of the votes, allowing that there are two turns and that a plurality of parties that express to bases and different social projects they can compete in the first. Canada has the same model of Great Britain in which no President but a head of State for life and legacy (Queen Elizabeth II), and where the head of Government is a Prime Minister elected by a single-member Parliament. As there is no proportional representation the winner tends to stay with everything (the British Labour holds 55% of the Parliament despite the fact that it took only 35% of the votes). U.S. shares with the first model being a presidential Republic but lacks two turns. USA is not a constitutional monarchy but his agent is not elected directly, and the candidate who wins a State gets all electors of this (which may be cases like the) Bush who came to the White House despite having lost on votes). With that system USA has managed to be the only major country that has managed to avoid m ACE of two parties.
