Abstract

The metaverse is emerging as a persistent, immersive digital environment that enables continuous social interaction, economic activity, collaboration, and identity development through constant data exchange. Unlike traditional digital platforms, it relies on sustained synchronisation and presence, generating extensive sensitive data such as identity attributes, behavioural patterns, biometric signals, spatial information, and transaction records across decentralised networks. This chapter examines the expanded cybersecurity risks arising from continuous data flows, highlighting how breaches can have long-term consequences due to persistent digital identities and ownership histories. As metaverse applications expand into healthcare, education, workplaces, and finance, security failures may lead to privacy loss, identity harm, and erosion of trust. The chapter outlines how cryptography supports secure communication, authentication, and data integrity through encryption, hashing, digital signatures, and key management, while addressing long-term risks from future computational advances.
