Abstract:
The healthcare market demands advanced, flexible, and secure solutions for personal health data sharing. In our paper, we present preliminary work that proposes a distributed infrastructure of negotiating agents for the healthcare domain. This infrastructure will support healthcare stakeholders to share and access patient health data in a secure way, thus providing benefits for patients and their treatment. Distributed ledger technologies and smart contracts can be considered as a basis for negotiations between distributed agents that carry health-related data. We present an overview of related work and outline the research methodology.
