| Outline of Final Research Achievements |
Individual recognition system using the biological information has been recently increasing everywhere, for example, in PC's, smartphones, and so on. In general, enrolled biological information should be stored as templates in the database or the IC card referred in the recognition process. The information of the templates should also be hidden to keep individual biological information secret.
In this study, I focused on fingerprints, and the two dimensional fractional Fourier transforms with different orders were performed for the divided areas of the fingerprint image in order to realize the highly secure fingerprint templates by use of the optical system. The condition to realize the templates with the highest recognition accuracy was also shown. Finally, the optical system to generate the fingerprint templates was proposed.
