A Literature Review on Virtual Reality Authentication

As virtual reality (VR) sees an increase in use in several domains such as retail, education, military; a secure authentication scheme for VR devices is necessary to keep users’ personal information safe. A smaller section of research focuses on the authentication schemes of VR devices. To further the understanding of this topic, we conducted a detailed literature review of VR authentication by exploring papers published till October 2020. A total of N = 29 papers were found. While many papers evaluate the accuracy of authentication methods, few conduct detailed user studies. In the user studies done, we found a lack of focus on diverse populations such as the elderly, with the mean age of the participants being 25.11. Our findings from the literature review give a detailed overview of VR-based authentication schemes and highlight trends as well as current research gaps. These findings drive future research direction to create robust and usable authentication strategies.
