Abstract or Summary:
Click-based graphical passwords, like other user-selected passwords, suffer from predictability problems. With click-based graphical passwords, user click-points form hotspots, areas of the image that are more likely to be selected, which e-criminals can predict and use to launch dictionary attacks. Our system, Persuasive Cued Click-Points, helps users select more random click-points and reduces the appearance of hotspots while still maintaining usability.
