International ClassH04L 009/32AbstractA method and apparatus for identifying authorized users of a secure system. A user of the secure system is prompted to enter a personal identification code which is then received into the secure system. The personal identification code entered by the user is then compared against a list of authorized personal identification codes. The user is identified to be an authorized user of the secure system only if the personal identification code entered by the user is present in the list of authorized personal identification codes. Each personal identification code on the list of authorized personal identification codes is arranged in a personal identification code format that includes a plurality of core digits and a plurality of check digits. A first of the check digits has a value that is dependent upon a first group of two or more core digits, and a second of the check digits has a value that is dependent upon a second group of two or more core digits, the first group of two or more core digits being different from the second group of two or more core digits. | |
