Slide-to-unlock revisited: two new user authentication techniques for touchscreen-based smartphones
暂无分享,去创建一个
We present two new user authentication techniques that look and feel like slide-to-unlock. The intention is to encourage users, who do not use a user authentication technique on their devices, to start using one. Results of a user study showed that the new techniques perform relatively well compared to slide-to-unlock and digit-lock, and users find at least one of the techniques easy to use.
