With the Gesundheitscloud.de, we are providing a patient-centric platform for health data which is run by a non-profit organisation. The Gesundheitscloud enables users to store and share their sensitive health data using a secure platform. By integrating different health data silos, we can provide patients with easy access to a holistic view of their health data. At all times, data privacy protection for each patient remains the highest priority. Once a patient permits specific access, a health provider benefits from an easy overview of the patient's medical history and relevant data. It empowers users to make informed and reflected decisions for their health care whilst keeping the data sovereignty at the core of this solution. With the help of this cloud architecture patients gain control of their health and ultimately receive a better health provision at lower cost. The Gesundheitscloud will serve as an ecosystem for selected health applications to deliver added value to the users. Further, users have the option to donate their health-data anonymously which will drive medical research to benefit society.
