| Popis: | E-health services handle a massive amount of sensitive data, requiring reliability and privacy. The advent of new technologies drives e-health services into their continuous provision outside traditional care institutions. This creates uncertain and unreliable conditions, resulting in the challenge of controlling sensitive user data dissemination. Then, there is a gap in sensitive data dissemination under situations requiring fast response (e.g., cardiac arrest). This obligates networks to provide reliable sensitive data dissemination under user mobility, dynamic network topology, and occasional interactions between the devices. In this article, we propose STEALTH, a system that employs social trust and communities of interest to address these challenges. STEALTH follows two steps: clustering and dissemination. In the first, STEALTH groups devices based on the interests of their users, forming communities of interest. A healthcare urgency launches the second, in which STEALTH disseminates user sensitive data to devices belonging to specific communities, subjected to the level of trust between devices. Simulation results demonstrate that STEALTH ensures data dissemination to people who can contribute toward an efficient service. STEALTH has achieved up to 97.14% of reliability in accessing sensitive data with a maximum latency of 170 ms, and up to 100% of availability during emergencies.
