Pick and Sort for Graphical Authentication
This work addresses the need for usable and flexible graphical authentication for specific user groups like children, but the results are preliminary and the approach is incremental.
The paper proposes a graphical authentication scheme called 'Pick and Sort' where users select and arrange visual elements in a grid. A preliminary study shows it is easy to learn and flexible, but login times are longer than conventional methods, making it suitable for non-time-critical scenarios.
We propose a graphical authentication scheme that follows a simple ``Pick and Sort'' design in which users choose visual elements and arrange them within a grid. Both the number of selected elements and the grid size are configurable, and the visual elements can be customized for specific user groups, such as children. A preliminary study with a prototype implementation indicated that the scheme is easy to learn and flexible to deploy. Although login times are longer than those of conventional authentication methods, the additional interaction may be acceptable in scenarios that are not time-critical, such as infrequent-access use cases or as a secondary authentication mechanism.
