Individual Authentication

There are relatively few ways of identifying an individual. When you are born, your birth is registered at a government records office, and the office issues a birth certificate to your parents. A few years later, your parents enroll you in school, presenting the birth certificate so that the school can issue you a school identity card. Still later, you submit the birth certificate and a photo to get a passport or a national identity card. In a similar fashion, each of us receives many other authentication numbers and cards throughout life.
