A Proposal of One-Time Biometric Authentication

- In biometric authentication, feature information of each enrolled person's biometric information is enrolled as templates. Secure databases or anti-tampered devices store the templates in general. The biometric information, however, is irreplaceable information, when it is compromised. Thereby, one must give a special attention to protection of such information. On the other hands, increasing internet economical services causes a motivation of implementing online biometric authentication. We propose a novel protection technique for the biometric information, especially the feature information and the templates. The point of our proposal is that the extracted features and the enrolled templates are transformed by one-time transformation that is generated in each authentication. The transformed features and templates travel through insecure communication line like the internet, and they are used in matching process. This technique causes security against eavesdropping and replay a...
