Efficient Shoulder Surfing Resistant PIN Authentication Scheme Based on Localized Tactile Feedback
Wei‐Chi Ku, Hao-Jun Xu · 2019
Conventional PIN authentication schemes cannot resist shoulder-surfing attacks. Therefore, various shoulder-surfing attacks resistant PIN authentication schemes using audio or tactile feedback have been designed for mobile devices. However, the efficiency of most existing shoulder-surfing attacks resistant PIN authentication schemes with sufficient security is unsatisfactory. Recently, devices with touchscreens supporting localized tactile feedback (LTF) have been developed, designed, patented, and/or implemented. It is promising that devices with touchscreens supporting LTF will be widely available in the future. In this paper, we present an efficient shoulder-surfing attacks resistant PIN authentication scheme, VpointsPES, based on LTF. VpointsPES can provide sufficient security and improved usability.
