Biometric technologies |
 |
In what follows there is a brief description of the principal biometric technologies, whose respective proponents - producers, research laboratories, think tanks - mostly tend to claim superiority over the others. A frequently used definition of "biometric" is that of a "unique, measurable characteristic or trait of a human being for automatically recognizing or verifying identity" ( http://www.icsa.net/services/consortia/cbdc/bg/introduction.shtml); biometrics is the study and application of such measurable characteristics. In IT environments, biometrics are categorised as "security" technologies meant to limit access to information, places and other resources to a specific group of people.
All biometric technologies are made up of the same basic processes:
1. A sample of a biometric is first collected, then transformed into digital information and stored as the "biometric template" of the person in question.
2. At every new identification, a second sample is collected and its identity with the first one is examined.
3. If the two samples are identical, the persons identity is confirmed, i.e. the system knows who the person is.
This means that access to the facility or resource can be granted or denied. It also means that information about the persons behaviour and movements has been collected. The system now knows who passed a certain identification point at which time, at what distance from the previous time, and it can combine these data with others, thereby appropriating an individual's data body.

Edward Heath
Conservative prime minister of Great Britain from 1970 to 1974. Of modest origins, Heath was educated at Oxford, where he was elected president of the University Conservative Association in 1937. In 1938, as chairman of the Federation of University Conservative Associations and president of the Oxford Union, he actively opposed the policy of appeasement toward Nazi Germany pursued by the Conservative prime minister Neville Chamberlain. He served in the army during World War II, worked in the Ministry of Civil Aviation in 1946-47, was editor of the Church Times from January 1948 to October 1949, and then became a member of a merchant banking firm.
