The HRR project will improve data security by facilitating use of safe servers for storage and analysis of research data from the health registries. Safety experts will evaluate the safety and user-friendliness of existing solutions such as TSD at the University of Oslo and SAFE at the University of Bergen, in order to make it easier for researchers and research institutions to make use of these solutions. The project will develop methods for sending encrypted data, and for ensuring that research data from health registries can be used optimally.
