This dissertation deals with the definition of privacy-aware dynamic coalitions by means of a formal framework, based on the Abstract State Machine (ASM) formalism. To this end, basic dynamic coalitions were defined and then extended with various access control mechanisms in order to integrate privacy-enforcing operations into the coalition's information sharing processes. The resulting framework consists of a number of ASM models, which define basic dynamic coalitions as well as dynamic

The thesis of this work states, that the proposed framework supports the understanding and the development of software for these coalitions throughout the typical software engineering life cycle: requirement capture, detailed design, validation and documentation. The thesis is validated in two case studies, which investigate the correctness of the thesis through the application of the framework in two dynamic coalition scenarios taken from the medical sector. The results show that the thesis holds for the presented case studies and gives insight also into how the model may be used to bridge the gap of understanding between software engineers and domain experts such as the medical doctors who contributed in the creation of the case study models presented in this work.
