C-1-3 自己組織化マップを用いたマルチタッチによるキーストローク認証手法 : 入力パターンの違いによる認証精度の比較(自己組織化マップ(1))

抄録

In this study, we have proposed, implemented and evaluated a keystroke authentication method using multi-touch-mode on smartphone and tablet PC as a usual operation for using mobile devices. In this article, we verified effectiveness of the keystroke authentication method using smartphone. Keystroke authentication is one of biometric authentications. We analyzed keystroke patterns using Self-Organizing Maps (SOM), and calculated authentication accuracy. Holding landscape-mode on a smartphone, we experimented assuming a game operation. As a future work, we will develop and extend our keystroke authentication method, which is able to identify as correct and authorized user whenever anyone use mobile devices. The precision of the authentication that we obtained is 84.0%〜86.4%.
