PassPoints: design and longitudinal evaluation of a graphical password system
TL;DR: PassPoints is described, a new and more secure graphical password system, and an empirical study comparing the use of PassPoints to alphanumeric passwords is reported, which shows that the graphical password users created a valid password with fewer difficulties than the alphan numeric users.
Proceedings ArticleDOI
Design and evaluation of a shoulder-surfing resistant graphical password scheme
TL;DR: The design and evaluation of a game-like graphical method of authentication that is resistant to shoulder-surfing is reported on, which shows that novice users were able to enter their graphical password accurately and to remember it over time.
Proceedings ArticleDOI
Authentication using graphical passwords: effects of tolerance and image choice
TL;DR: Results show that accurate memory for the password is strongly reduced when using a small tolerance around the user's password points, which suggests that many images may support memorability in graphical password systems.
Authentication Using Graphical Passwords: Basic Results
Susan Wiedenbeck,Jim Waters +1 more
TL;DR: The results show that the graphical group took longer and made more errors in learning the password, but that the difference was largely a consequence of just a few graphical participants who had difficulty learning to use graphical passwords.
Journal ArticleDOI
Using a grounded theory approach to study online collaboration behaviors
Susan Gasson,Jim Waters +1 more
TL;DR: The substantive theory of action that was generated by this process provides an original contribution to theories of collaborative online learning by accounting for both visible and invisible learning strategies that explain the role of thought-leaders in a community of inquiry and account for vicarious learning.
