Summary - Y.4812 (03/2025) - Interoperability of the identity of Internet of things devices across metaverse platforms

Recommendation ITU-T Y.4812 describes identity interoperability for IoT devices across metaverse platforms and provides relevant technical features and reference framework.
With regard to the Internet of things (IoT) (Recommendation ITU-T Y.4000), each IoT device may have a single or multiple unique identities in multiple IoT systems. Similarly, each IoT device also may have a single or multiple identities in multiple metaverses. The identity of an IoT device usually includes a unique identifier and a corresponding identity object (Recommendation ITU-T Y.4811).
Although it may take advantage of one IoT device having one unique identity in multiple metaverses, there are challenges; how those metaverses identify, authenticate, and authorize the IoT devices when they are roaming across metaverse platforms, and how the trustworthy shared storages interact with each other to support identity interoperability across storages.
