Data-centered value creation platform for interactive, assisting service systems

Data are considered the raw material of the century. The World Economic Forum designated personal data as a new asset class back in 2012. A shift to digital business models on the basis of data is in demand and already discernible today. The project "DaWID" aims to research and test a data-centered value creation platform for the transparent and sovereign administration of their own data by users.

The challenge

Technical solutions in the area of human/technology interaction are intended to assist people of any age in all circumstances. Many assistance systems are data-driven. A digital twin of people and their environment can be created with the help of data. When collected data and combined services are orchestrated and brought into an overall context, this results in data-driven value chains. Thus data will not only be collected and evaluated, but also enriched and refined along the entire value chain and upgraded into services by companies. There is however the risk of losing sovereignty over one’s own personal data.

Our contribution

DaWID aims to research and establish a data and service-driven ecosystem for interactive assistance systems. Factors of special importance within this ecosystem are the data economy and data sovereignty. For one thing, users are to be given sovereignty over their data with relevant controlling functions. Data flows need to be transparent and the use of data must be traceable. For another, novel cooperation and business models are to be enabled from the data economy perspective in order to pursue the objective of the digital value creation process – data refinement. People will also gain a feel for the value of their data through the assignment of a monetary amount to the release of data.



DaWID is a meta-platform that serves as a broker between service providers. Due to the inclusion of International Data Spaces, the focus is on industry, leading to the emergence of new business models. Results include the definition of user requirements and offers, the convergence of individual services into holistic service systems, semiautomatic data pricing, data processing chains for contractual relationships and user consent, and ethical/legal analyses regarding data owners.

Position Ppapier

"Data Sovereignty and Data Economy-Two Repulsive Forces?"

How do data sovereignty and data economy interact? The position paper explores this question using a holistic approach that includes data sovereignty, data economy, data law, and data ethics. Ten areas of tension were identified for which data-driven value chains are being tested in the DaWID project, taking data sovereignty into account. The authors provide initial recommendations for action for operators of data ecosystems to enable data sovereignty for their data market participants, taking into account the European and German data strategy.
