Abstract
A computer system and method is provided for authenticating the identity of an authorised person. The basic concept is that a permitted user of an identification article such as a credit card will be given a personal identification number with the card and will be instructed not to use the personal identification number in the form in which it has been given but only to use deliberately corrupted versions thereof. The computer system is then set up to detect whether the personal identification number offered for use is a properly corrupted version of the original personal identification number.
