Towards Integrated Data Control for Digital Twins in Industry 4.0.

The Digital Twin is currently a widely discussed topic for presenting and exchanging information on physical assets through virtual networks. Especially the digitisation of the manufacturing industry, Industry 4.0, drives the implementation of Digital Twins as part of integrated production processes. Hence, the protection of sensitive data becomes an evident challenge. We contribute by determining the require- ments of current scenarios, the descriptive expressiveness of necessary vocabularies, and by formalising the involved operations. The Asset Administration Shell is used as a concrete metamodel for Digital Twins and is combined with the data sovereignty and enforcement concepts of the International Data Spaces to illustrate how these concepts can be implemented into a comprehensive Industry 4.0 scenario.
