TRAC: A Therapeutic Regimen-Oriented Access Control Model in Healthcare

Access control is a significant strategy to protect security and privacy. Due to electronization of health information, medical access control attracts lots of attention in the research community. The existing medical access control approaches mainly focus on doctors' roles and behaviors, such as role-based access control (RBAC) and risk-based access control. However, various therapeutic regimens can also lead to unauthorized access. The current researches do not consider access control authorization in terms of therapeutic regimens. In this work, we present an access control model based on therapeutic regimen. Our model, TRAC, proposes an access strategy by analyzing feasibility of therapeutic regimens. Our experiments show the effectiveness of TRAC in terms of precision. Moreover, our model also contributes to choosing better therapeutic regimens for patients.
