ABSTRACT
With the emergence of the Covid-19 disease, hospitals and health care professionals (HP) had to deal with a huge number of patients presenting with the virus that kept increasing every day, resulting in the increase of the pandemic transmission. To deal with this issue, minimize patients' and healthcare professionals' exposure, and be able to treat all patients, HP turned to home hospitalization. In-home hospitalization, doctors need to monitor their patient's health status remotely, and patients need to share this data with them. But in this scenario, patient privacy is exposed to several external threats and intrusions, sometimes resulting in the loss of patient life. To deal with the above issues, our focus in this article is on access control (AC). Thus, we propose a Blockchain (BC) smart contract-based model, where each object owner creates one ACC (Access control contract) for each subject in the system and defines his access policies in it. © 2022 IEEE.
