Security Model for an Economy-Enabling Metaverse

This paper proposes a comprehensive security model developed by Moving Picture, Audio and Data Coding by Artificial Intelligence (MPAI) for the Metaverse Model -Technologies (MPAI-MMM-TEC). The model enables trustworthy participation in an interoperable, economy-supporting metaverse. Motivated by the limits of perimeter-based cybersecurity in immersive, multi-stakeholder environments, the model addresses metaverse-specific risks such as cross-world identity abuse, virtual asset and economic manipulation, fraud, and IP management. The design defines functional requirements and maps them to security capabilities. These include interoperable authentication and authorization, trust establishment, verifiable provenance and integrity (for media and assets), privacy-preserving data handling, and accountability mechanisms suitable for distributed interactions. The paper describes how MMM architectural components support secure participation and trustworthy trades between stakeholders. An initial implementation and preliminary assessment are presented to demonstrate feasibility and provide a baseline for future development.
