Summary

The metaverse is an emerging virtual world where users interact, create, and engage in various activities. As it evolves, privacy concerns grow due to the vast collection of personal data. The metaverse relies on AI, XR, MR, and 5G/6G to enhance experiences but raises security risks. Protecting user data, securing interactions, and preventing unauthorized access are critical. This paper explores key privacy challenges and examines technical solutions like differential privacy, homomorphic encryption, and federated learning, along with broader sociotechnical issues.
