Unfortunately, some problems impeding the general acceptance of mhealth such as privacy protection, limitation of wireless networks and handheld devices are still common. Challenges such as unreliable data repositories and limited connection speeds in resource-limited environments are also evident. The inadequate capabilities of hand-held devices and wireless systems make these Public Key Cryptography based frameworks unsuitable for mobile networks. Moreover, these protocols were designed to preserve the customary flow of health data, which is vulnerable to attack and increase the user’s risk. This research drew its foundations from literature and theoretical review and used qualitative approaches. In this paper, the researchers build on existing concepts of Medical Information Systems and use of Symmetric Key Infrastructure to design a framework for secure access to personal electronic health records. The framework provides identity protection for a patient from all forms of unauthorised data access. The framework not only reduces the computational operations between the engaging parties, but also achieves privacy protection for the user. Validation results from ICT experts demonstrate that the designed framework is applicable to secure access to personal medical health records in resource-limited settings.
- ItemOn the challenge of adopting standard EHR systems in developing countries(Association for Computing Machinery (ACM), 2013) Ssembatya, Richard; Kayem, Anne V.D.M.; Mardsen, GaryElectronic health record (EHR) systems are a popular mechanism for accessing health records in the developed world and have contributed towards improved and cost-effective health care management. However, the development of appropriate and scalable EHR systems in developing countries has been difficult to achieve because of certain limitations inherent in the technological infrastructure. In this paper, we present a comparative study of 19 EHR systems in terms of the security and usability of these systems within the context of the developing world. Our aim was to investigate whether online health services designed for developed countries can be adopted for EHR systems in developing countries. The investigation was based on a number of dimensions such as development environment, system platform, type and access control standards found in the National Institute for Standard and Technology (NIST) and Certification Commission for Health Information Technology (CCHIT). Our research indicates that all the systems evaluated require online access control decisions. Solely relying on an online access control system is limiting, particularly in developing countries where access to the server can be disrupted by a number of disastrous events.
