Designing Trustworthy Immersive Systems at the Convergence of Metaverse, AI, and CybersecurityThe metaverse is rapidly evolving into a persistent, interoperable constellation of immersive worlds underpinned by XR, real time 3D engines, digital twins, edge 5G 6G, Web3 economies, and cross platform identity systems. AI is central to this shift while simultaneously expanding the attack surface through identity spoofing, deepfakes, smart contract exploits, biometric leakage, and adversarial threats. As these environments scale, ensuring trust,
