Abstract: Metaverse is the digital technology medium of the next generation Internet. In the metaverse, individuals can realize deeply mediated virtual digital existence. However, there are also challenges to data security, and personal information protection is faced with an unprecedented crisis: the extension of personal information continues to expand, personal biological information is collected, the traditional “informed consent” principle is impacted, and the traditional information supervision model is broken. In the digital media space of metaverse, the protection of personal information needs to be tackled urgently by constructing technology-facilitated rules, clarifying the legal positioning of personal biological information, layer-dynamic consent principle, and balancing rules between platforms and individuals. Strengthening the exploration of the rules of the metaverse is of great significance to personal data security and even national strategic security.

Key words: metaverse, data governance, media space, personal information, data security
