B-2-1 Biometrics Authentication using Flick Operation on Smartphone : Verification of Practical Use on System Environment

Abstract

Large amounts of important personal identifiable information have been handled on smartphones and tablet PCs nowadays. Therefore information security measures are developed and the importance of identification for uses is increasing more and more. We think a general identification by a passphrase is inadequate and it is necessary to authenticate user validation even at the time of smartphone operation. In this study, as the authentication method that considers operability, practicality and simplicity for smartphone, we propose a biometric authentication method using a flick operation. We analyzed flick operation patterns using Self-Organizing Maps (SOM), and calculated authentication accuracy. We experimented with several conditions. The precision of the authentication that we obtained is 73.98%〜81.46%. As a future work, we will develop and extend our flick authentication method, which is able to identify as correct and authorized user whenever anyone use mobile devices.
