A Systematic Literature Review for Facilitating Authentication for the Disabled

In the modern world today, many online services require user authentication of some kind to log in to access its features, be it social media, banking, work or entertainment. For most people, the process of completing this task is straightforward, even if occasionally challenging or time consuming. However, disabled people can face additional challenges; whether through not being able to complete a verification due to lack of speed in responding, lack of necessary information provided to them or from security vulnerabilities that become exposed because of the nature of their disability. This paper aims to address these issues with a potential solution that provides a usable system for a disabled person to be able to access services easily without compromising on security. By way of a systematic literature review, this paper reinforces the need for such a system by highlighting fundamental shortfalls, and areas where advancements can occur and thereby advocating firm business incentives for doing so. Part of this review involved research for a proposed system architecture which illustrates how an authentication system can operate for disabled people while retaining both usability and security, along with a supporting business perspective to provide a sustainable lifecycle for the system.
