Nowaday, Many equipments like TabletPC, Digital kiosk, ATM using touch-panel service instead of keyboard or button, to support intuitively input for user. Furthermore these days touch-panels recognize up to 5 contact points using recent technology. On this study, I Introduce password input/store methodology on multi-touch environment. On past, User must input password 1 character by 1 character, like [1, 2, 3, 4]. but, on multi-touch environment user can input more than one character at the same time, like [(1,3), 2, (3,4), (1,2,3)]. In result, users can use password more intensely. This study is utilized post security technology study on multi-touch environment.
