Journal ArticleDOI
On-line trust: concepts, evolving themes, a model
TL;DR: The definitions of trust are analyzed, the relevant dimensions of trust for an on-line context are identified, and a definition of trust between people and informational or transactional websites is presented.
Journal ArticleDOI
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.

TL;DR: This article summarizes and classifies research on end-user software engineering activities, defining the area of End-User Software Engineering (EUSE) and related terminology, and addresses several crosscutting issues in the design of EUSE tools.
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.
