Argianto Rahartomo, AmirHossein Jamshidipoor, Mohammad Ghafari

TL;DR
This paper introduces a customizable graphical authentication scheme called 'Pick and Sort' that is easy to learn and flexible, suitable for scenarios where security outweighs speed.
Contribution
The paper presents a novel 'Pick and Sort' graphical authentication method with configurable elements and demonstrates its usability through a preliminary study.
Findings
Scheme is easy to learn and flexible to deploy.
Login times are longer than conventional methods but acceptable in certain scenarios.
Customizable visual elements can be tailored for specific user groups.
Abstract
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.
