  Privacy is a key challenge for continued digitalization of health. The
forthcoming European General Data Protection Regulation (GDPR) is transforming
this challenge into regulatory directives. User consent provisioning and
coordinating across data services will be the keys in addressing this
challenge. We suggest a privacy-driven architecture that provides tools for
providing user consent as a service. This enables managing and reusing private
health information between a large amount of data sources, individuals and
services, even when they are not known beforehand. The proposed architecture
integrates data security and semantic descriptions into a trust query framework
to provide the required interoperability and co-operation support for future
health services. This approach provides benefits for all stakeholders through
safer data management, cost and process savings, multi-provider services, and
services based on emerging new business models.
