In this chapter, the authors describe the software architecture of a commercially run home assistance system that allows patients or elderly people to stay longer at home. Since such systems often have to handle sensitive medical information, the protection of the privacy is a major concern. In addition, legislation often restricts access to health information to qualified persons (i.e. medical personnel), who are not always available in a commercial setting. The home assistance system can offer several services, ranging from scheduling necessary tasks and following up their execution, to monitoring the patient's health status and responding promptly to requests for help or in case of emergency situations, and all this without the need to maintain personal medical data or identifying information about patients and caregivers in the home assistance centre. |
