Applying Digital Twins in Metaverse: User Interface, Security and Privacy Challenges

Abstract

Digital Twins (DTs) are a conventional and well known concept, proposed in 70s, that are popular in a broad spectrum of sciences, industry innovations, and consortium alliances. However, in the last few years, the growth of digital assets and online communications has attracted attention to DTs as highly accurate twins of physical objects. Metaverse, as a digital world, is a concept proposed in 1992 and has also become a popular paradigm and hot topic in public where DTs can play critical roles. This study first presents definitions, applications, and general challenges of DT and Metaverse. It then offers a three-layer architecture linking the physical world to the Metaverse through a user interface. Further, it investigates the security and privacy challenges of using DTs in Metaverse. Finally, a conclusion, including possible solutions for mentioned challenges and future works, will be provided.
