报告摘要：
Smartphones such as Android phones and iPhones are widely adopted worldwide and users’ privacy are challenged by various attacks. There is a great need for a robust user authentication mechanism. Up to now, textual passwords are the most widely adopted authentication method, but they are vulnerable to many known limitations. Graphical password is considered as one alternative to complement the existing authentication systems, based on the observation that humans can remember images better than textual information. In order to obtain a large password space, geographical passwords have received much attention, which enable users to select one or more places on a map for authentication. In particular, users can perform more types of gestures like touch movement on mobile devices as compared to a common computer. Based on this observation, this talk introduces TMGMap, a touch movement-based geographical password scheme on smartphones, which allows users to draw their secrets on a world map via touch movement events.
