Towards Scalable, Secure and Privacy-Preserving Metaverse

Prof. DAI Hong-Ning
Associate Professor
Department of Computing Science, Hong Kong Baptist University (HKBU)


The metaverse is essentially constructed by multiple technologies, including virtual reality (VR), augmented reality (AR), mixed reality (MR), artificial intelligence (AI), digital twin (DT), blockchain, and 5G communications. The advent of the metaverse has proliferated a number of VR/AR apps on top of diverse VR/AR devices, such as Meta Quest 2, MS Hololens, Sony PlayStation VR, ByteDance Pico, and Apple Vision Pro. Meanwhile, diverse metaverse applications have emerged, such as gaming, healthcare, industry, creator economy, and digital arts. However, the current development of the metaverse is still in its early stage because of the complexity and heterogeneity of the entire system, which cannot be scalable to fulfill the increasing number of participants as well as the stringent demands of metaverse applications. Moreover, emerging security vulnerabilities and privacy-leakage concerns have also prevented the metaverse from wide adoption. In this talk, I will first briefly review the Metaverse as well as relevant technologies. I will then elaborate on its challenges as well as potential solutions. Finally, I will discuss several future directions in this promising area.
