Safe and robust calibrated measurement systems for digital transformation

In the GEMIMEG-II project, a secure, continuous, legally compliant end-to-end availability of information for the implementation of reliable, networked measurement systems is being developed. The focus of the overall project is on metrology (calibration, referencing, calibration), i.e. trust and quality information about measuring devices, sensor networks, digital twins and data analysis methods(transformation). In this context, the quality of the data obtained and the robustness of the statements and conclusions derived from it are of central importance, especially for industry and electronic legal transactions. The reliable and verified determination and assurance of data quality is a prerequisite for the successful use of data as an economic asset.

The project group for constitutionally compatible technology design(provet) at the Scientific Center for Information Technology Design(ITeG) at the University of Kassel, headed by Prof. Dr. Alexander Roßnagel, ensures that the technologies and techniques to be developed in GEMIMEG-II are designed in a legally compliant and legally compatible manner by providing continuous and integrative legal support.

In the sub-project "Legally Compatible Design and Application", provet is working on the technological questions from a jurisprudential point of view. The goal is legal certainty and protection of fundamental rights for companies, authorities, employees and customers. In GEMIMEG-II, provet provides integrative research and consulting on legal issues of electronic commerce, electronic administration, data protection, product liability, evidence, trust services and IT security.

In order to meet the legal requirements of these legal areas, provet makes design proposals already in the development phase, by which the requirements of the law can be implemented as well as possible(legal compatibility)

Provet is developing a catalog with suggestions for the legally compatible design and application of digital transformation concepts in digital metrology and measurement technology (KORA). In addition, the design proposals will already be incorporated into the realbeds developed in the overall project and legally evaluated there (legal simulation studies). This will promote the competitiveness of the developments by creating confidence in the technologies that are otherwise still untested in electronic legal transactions and electronic administration.
