Privacy Enforced Access Control Model for Secured Data Handling in Cloud-Based Pervasive Health Care System

Abstract

Health care is a significant application of pervasive computing. In recent years, the pervasive health care applications are replaced by cloud-based health care applications thus solving the problem of scalability and computing cost. In a cloud-based pervasive health care data security and privacy becomes a greater concern. The key contribution of this paper is to provide high privacy, data confidentiality, availability against the health data and this is achieved using the proposed access control model which uses a PR based approach for providing access control to various users of the system. Privacy rating (PR) is calculated for both the user and the data to provide access to any data that is being requested by the user. The results achieved shows that the proposed model achieves high level of privacy and security for the data stored in the healthcare system.
