1. An identification data recording method for a certification identifying medium, comprising the steps of:
- encoding predetermined basic data into N encoded data using N algorithms, wherein N is a positive integer;
detecting N encoded data from an information identification code strip, said information identification code strip being printed or laminated on said certification identifying medium with magnetic materials;
decoding said detected N encoded data using said N algorithms;
comprising said decoded detected N encoded data with said basic data;
encoding said decoded detected N encoded data using said N algorithms when said compared data is identical; and
,recording said encoded data on a magnetic recording strip, said magnetic recording strip being provided on said certification identifying medium.

Abstract
An identification recording data method for an identification medium includes the steps of printing or laminating an information identification bar code strip and then affixing a magnetic recording strip to the identification medium. A data set is encoded into N encoded data using N algorithms. The bar code strip has the N encoded data recorded thereon. The magnetic recording strip has the data set recorded thereon. The N encoded data is decoded and compared with the data set recorded on the magnetic strip. Comparision of the data yields a determination as to the integrity of the identification medium.
