Personally Controlled Electronic Health Record (EHR)

eHealth, the future of health care system, is gaining popularity in quick succession in the context of Australia. The core of eHealth is the Electronic Health Record (eHR) system which functions to record patient health information. In the era of the current communication networks, healthcare systems should utilise the advantages of storing, fetching and distributing the information between different healthcare stakeholders efficiently. To make the system secure in respect to the access to eHRs, the Personally Controlled Electronic Health Record (PCEHR) has recently been proposed. Despite the claim of PCEHR being controlled by the patients, vulnerabilities of disclosing credentials by the healthcare professionals and system operators are still present in the system. Other threats include, but not limited to, sensitive data in wrong hands, vulnerable authentication, and confidentiality. Moreover, an uninterrupted application of the security principle of electronic data files necessitates encrypted databases. So far, many research works have been progressed to confirm the patient's privacy. In most of them, the healthcare authority can get the consent to retrieve the patient's eHRs. These vulnerabilities may impact the patients and warrant the necessity of emerging of robust and effective authentication and access control schemes for eHRs.

Various methods of authentication are available using passwords, secret keys, tokens, and bio-metric features are the ones. An authentication system is required be elementary, fast and protected against unlawful use. In this dissertation, we propose multi-factor, multi-channel based authentication system which overcomes most of the drawbacks of existing the authentication system. Moreover, due to the simplicity of the proposed method, it is user friendly while ensures the strong security of
