DBA: Direction-Based Authentication in Virtual Reality

To protect the privacy and security in the emerging metaverse, vari-ous authentication methods have been designed for virtual reality. In this paper, we propose a novel selection-based authentication method called the Direction-Based Authentication (DBA). To enter a password, the user visits a sequence of four different environments and selects a direction in each of them as a symbol via either physical turning or panel-controlled snap-turning. The goal is to provide an authentication technique that is both memorable and efficient to use without compromising its security. Preliminary testing shows that the entry time of DBA can be as short as 6–12 seconds.
