The document presents a joint initiative that addresses how to federate identity trust across different data spaces at an international level.

As a use case, it explores data exchange between the EU and Japan for a ‘battery passport’, using the Japanese gBizID system on a pilot basis, so that a data consumer in Europe can use information from a Japanese provider to comply with the EU Battery Regulation.

The approach focuses specifically on ‘Identity Trust’, that is, trust in the existence and authenticity of the participating entities.
