Over 3 years, members of the BloG³ project design, develop, implement, and evaluate a blockchain-based system for the management of health data. The system enables oncology patients leaving the Charité hospital in Berlin to manage access rights to their data via a smartphone app. This allows patients to grant data access to other doctors, hospitals, and nursing services in the context of follow-up care. The blockchain-based platform integrates different health information systems and builds a bridge between different electronic data sources. The main objective of this project is to investigate to what extent the benefits of this technology can be transferred to real applications in the German health care system from a technical, economic and legal point of view.

Within this project, KIT particularly works on the design of the system architecture, the perception of the system by different user groups, and the development of incentive mechanisms for the continuous use of the platform. The project consortium comprises partners from health care (Charité Berlin, Pflegewerk Berlin), computer science research (Research Center for Information Technology, Free University of Berlin, KIT), and industry (C&S Computer und Software GmbH, nubedian GmbH, easierLife GmbH, CircularTree GmbH, ITK Engineering AG).

BloG3 is funded by the German Federal Ministry of Education and Research. As part of the Federal Government's new high-tech strategy, it contributes to strengthening research on human-technology interaction in the presence of digital platforms. A key objective is the strong participation of start-ups and small and medium-sized enterprises (SMEs) in order to use and expand the existing innovation potential of German SMEs.
