The common pin-entry schemes are vulnerable to observation attacks. In order to enhance the resistance to observation attacks, the pin-entry schemes for mobile devices based on audios and haptics are planned. However, none of existing observation attacks resistant cannot provide good security and usability compared to the new observation attacks. The pin-entry schemes can achieve both security and high usability. Herein, we have a tendency to propose a new observation attacks resistant pin-entry scheme, Loc-happin for touchscreen devices providing localized haptic feedback. By victimization the technology of localized haptic feedback, the usability and the resistance to observation attacks are improved. Furthermore, the user can choose the efficiency-security setting suitable for him.
