Abstract

As the development of computer science and smart health-care technology, there is a trend for patients to enjoy medical care at home. Taking enormous users in the Smart Health-care System into consideration, access control is an important issue. Traditional access control models, discretionary access control, mandatory access control, and role-based access control, do not properly reflect the characteristics of Smart Health-care System. This paper proposes an advanced access control model for the medical health-care environment, task-role-based access control model, which overcomes the disadvantages of traditional access control models. The task-role-based access control (T-RBAC) model introduces a task concept, dividing tasks into four categories. It also supports supervision role hierarchy. T-RBAC is a proper access control model for Smart Health-care System, and it improves the management of access rights. This paper also proposes an implementation of T-RBAC, a binary two-key-lock pair access control scheme using prime factorization.

Summary

INTRODUCTION

A small family Smart Health-care System is needed for patients who need medical care. According to this system, patients, doctors, nurses and guardians of the patients can share the health-care information. Once the users in the health-care system leave, it needs the supervisor to reset every detail of the user When it happens to massive subjects, the changes of organizations are complex. The purpose of this paper is to propose a suitable access control model, T-RBAC [6,7], for the health-care environment. Task and role are main aspects of the proposed model, and they have various characteristics related to access control.
