A1-2 Experiment of extended picture password method using behavioral profile for a biometrics authentication

Abstract

Smartphones are equipped with various personal authentication functions. Accordingly, in the previous experiment, we have tried to develop a security enhancement method for pattern authentication of smartphone. To discriminate individual users, we applied self-organizing maps (SOM) for the authentication, which is based on locus of figure drawing and angle of device holding. The result suggested the possibility to enhance the accuracy of pattern authentication. In this article, we propose an extended picture password method using behavioral profile and SOM for a biometrics authentication using previous results.
