THE T2ROL ACCESS CONTROL MODEL FOR MOBILE HEALTH SYSTEMS IN DEVELOPING COUNTRIES.

In resource constrained settings faced with scarcity of health practitioners and poor infrastructure, coupled with the high penetration of mobile technology, use of mobile technology seems to be a feasible way of improving health care service delivery especially in developing countries. However, mHealth systems are faced with security and privacy challenges such as third party attacks and eavesdropping among others. Much as the available security models such as RBAC, TMAC and TBAC have been successfully used in mHealth systems, security and privacy issues still persist. In addition, these models may not be applied in some contexts in developing countries such as in situations where mobile devices are shared and where some users are illiterate among others. This paper presents a hybrid model based on role-based, team-based and task-based models specifically tailored to the context of mobile health in developing countries. In this paper we discuss the formal description of the model and give an application example. [ABSTRACT FROM AUTHOR]
