Personal health data are essential for developing new therapeutic methods, testing innovative drugs, optimizing health care or in pathology. By collecting, collating and processing health data, processes for users can be optimized, disease management carried out and medical treatment linked with research to generate new insights.

Against this backdrop, the concept of digital self-determination becomes increasingly important - the informed consent of those affected by the collection and use of health data is an essential element in the utilization of personal data. In particular, the protection of self-determination requires that those concerned should be in a position to determine for themselves the purposes for which their data is used. They should be enabled to decide independently which data they want to make available for which purposes. In view of the growing volume of data collected and the ever more complex ways in which it can be used, the parties concerned are faced with an ever-growing challenge of having to weigh up appropriately what it means to give away personal data and what consequences follow from this decision, and, ultimately, to make a self-determined decision about releasing this data.
