Abstract:
This chapter introduces data privacy and its significance in the metaverse to the readers. It introduces several data privacy policies, privacy enhancing techniques (PET), and discusses some existing literatures on data privacy issues in the metaverse. This chapter seeks to educate readers on the various methods and technologies available to protect personal and sensitive data throughout the entire data lifecycle (collection, storage, use, and transmission). In addition, it discusses how these privacy-preserving techniques can be used to secure metaverse data and describes the most recent findings from studies conducted on the PET methods to improve these practices. The chapter also includes suggestions for additional research and development that will help readers take the first step toward enhancing data privacy techniques in the metaverse or incorporating existing technologies into privacy-enhancing metaverse applications.
