Create an anonymous ID based on a personal ID number and a combination of the Initials and the year of birth (Initials+YoB). An exhaustive search can find the original values matching the anonymous ID unless a strong Key is added for security. Therefore, make sure the personal ID number cannot easily be used to identify a person (more information).
