A Proposed System of Trust Based ECG Monitoring for Ubiquitous Healthcare Applications

Ubiquitous computing technologies can be used to provide better solutions for healthcare of patients at home or hospital. Moreover, ubiquitous computing is also characterized by partial views over the state of the global environment, implying that we cannot guarantee that an environment can always verify the properties of the mobile entity that it has just received. Secure in this context encompasses both the need for cryptographic security and the need for trust, on the part of both parties, that the interaction is functioning as expected. In this paper, we propose a trust-based system of ECG Monitoring for ubiquitous healthcare applications. A ubiquitous trust domain is introduced to collaborate entities making of autonomous trust-based decision for ECG monitoring using wireless sensors. Wireless controller that can send monitored information to the service centre and provide a feedback, if necessary, to the patient from medic. If an emergency is detected the monitoring services gives alarm condition to doctor’s personal digital assistant.
