Exploring Usability Effects of Increasing Security in Click-Based Graphical Password
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
Graphical passwords have been proposed to address known problems with traditional text passwords. For example, memorable user-chosen text passwords are predictable, but random system assigned passwords are difficult to remember. We explore the usability effects of modifying system parameters to increase the security of a click-based graphical password system. Generally, usability tests for graphical passwords have used configurations resulting in password spaces smaller than that of common text passwords. In this paper focuses on the integrated evaluation of the Persuasive Cued Click Points graphical password authentication system, including usability and security. An important usability goal for authentication systems is to support users in selecting better passwords, thus increasing security by expanding the effective password space. We chose to study Persuasive Cued Click-Points (PCCP),a click-based graphical password system in which users select click-points on more than one image. PCCP has been shown to have good usability, while avoiding hotspots that have been shown to affect the security of other click-based graphical password systems .
