Trial Application of Risk Assessment Method for Metaverse

In recent years, the use of the metaverse has been increasing for activities such as gaming, shopping, and sightseeing. While the metaverse has various advantages, there are also concerns about risks such as security problems. Unless appropriate risk assessments are carried out in advance and countermeasures are taken, serious damage may occur during metaverse use. However, there has been no proposal or application of a risk assessment method for the metaverse. Therefore, we considered an improved method by applying the method previously developed by the authors for IoT risk assessment to the metaverse gaming environment and developed the Multiple Risk Communicator for Metaverse (MRC-MV) as a risk assessment method. Furthermore, in this research, by trial application of MRC-MV to metaverse shopping, we obtained results that show that this method is effective for this activity. This method not only clarifies threats with high risks, but also makes it possible to clarify high-priority countermeasure groups by semi-quantitatively considering countermeasure effectiveness, cost, and usability.
