CAPM: Context-Aware Privacy Model for IoT-Based Smart Hospitals

The emergence of IoT technology can integrate connected digital wearable devices in the health field. In this context, the smart hospital is created to facilitate and improve the quality of patient's medical life. However, uncontrolled access to personal and health information of patients can disrupt the smooth functioning of smart hospital services. Consequently, the protection of patient privacy remains a big issue that must be addressed. In this paper, we propose a Context-Aware Privacy Model (CAPM). It aims to secure the exchanged and shared patient's information during his hospital stay. To evaluate effectiveness of our proposal, a series of simulations are carried out using NS3. The obtained results demonstrate the efficiency of our protocol in terms of communication delay, Authentication delay, and pseudonym generation time.
