Comprehensive eHealth System Design for Privacy Protection

In this report, we describe the design of a comprehensive eHealth system that offers a range of services allowing patients or elderly people to receive necessary care in the home setting. The system architecture allows home assistance to be offered by commercial entities, thus propelling its deployment. Since home assistance systems often have to handle sensitive medical information, protection of privacy is of utmost importance. The services offered by the home assistance system range from monitoring patient’s health status and responding to requests for help or emergency situations in a timely manner to scheduling requested tasks to the caregivers of the patient and following up their execution. The design of the system is flexible and allows seamless integration of new services and service providers. Most importantly, the deployment of these services does not require maintaining personal medical data or identifying information about patients and caregivers in the home assistance centre.
