A Constraint-Based Access Control Model for Information Distribution in Nigeria’s Healthcare Systems
Journal Title: American journal of Engineering Research - Year 2016, Vol 5, Issue 6
Abstract
Sharing clinical data within the domain of Nigeria’s healthcare system through an Information Technology central platform appears to be a major challenge, perhaps due to low technological development of the country. This deficiency constantly exposes the supposedly private data of patients to the wrong hands through the current hand-to-hand transfer of such data within the healthcare domain. The manual transfer, as observed is appalling; and has subjected the healthcare information distribution system to breaches of security, delivery, confidentiality and ethical risk issues. This research addresses these deficiency with a unique contribution to already existing electronic NHMS record keeping systems by designing and developing a framework with a proof of concept for centralization of patient clinical data for Nigeria healthcare delivery. It provides an electronic hand-shake using an access control model that can store clinical data of all patients and share the same data among the concerned healthcare professionals in the healthcare domain. The specific objectives of this research are to develop a constraint based framework for access control in an information distribution system that will generate a pattern of misuse and also provide a central information platform for the control of access related activities. The distributed system is a cloud server where information of the patients’ are stored and can be easily accessible by the NHMS personnel or doctors remotely. Achieving this objective compels the study to adopt authentication and authorization method at inter / intra organizational level for the security and delivery of patients’ clinical data. The use of role based access control tools were used to regulate individual access rights to the network resources based on security policies and rules defined in the program. The developing platform is Windows OS and the web server is Apache. The system was designed to securely manage and coordinate patient’s clinical profiles, dynamically identify levels of data to be accessed, grant authorized access to clinicians/doctors, and privileges to online information transfer / delivery. In order to access a resource, users must meet the regulatory conditions of the policy class which is in conformity with organizational standards as stipulated by the Federal Ministry of Health in Nigeria that regularize healthcare policies. The system was designed to be flexible and adaptive in order to allow users pass on their rights of access to other users, permission given for right of access can be withdrawn based on the stipulated restrictions that have been defined in the program. The research is a novel model that is in compliance with healthcare standards in relation to data and service user-friendliness. The designed framework facilitates flexibility to any deployed environment.
