Abstract
Whenever an individual uses a service, registers for email, completes a financial transaction or goes to a doctor, Some level of personal information has to be provided. The fact remains that whether or not you are aware specific data and information about you is captured and stored by both government and non-governmental agencies. Citizens have to develop a level of trust in both government and other sectors that the data they provide is secure and will be kept confidential. Hence, it is the role of these agencies to adopt data protection practices that will limit or completely eliminate data exploitation, manipulation and theft. The health sector in Nigeria continues to be a victim of data theft or mismanagement of patient medical data and this is credited to the poor and terrible way personal data are managed including poor medical record management system. Over the years there have been reoccurring cases of missing medical records or mismanaged record keeping in healthcare organizations which often leads to legal actions against such healthcare organizations or use of patient data for malicious intent. In order to overcome this, the patient record system must be protected to thwart off multiple duplicitous behaviours and ensure confidentiality and reliability. Cryptography presents various methods and cryptographic algorithms to ensure security in file transfer and secure record management. Thus, the aim of this study is to propose a cryptographic enabled Electronic Medical Record system that utilizes the concept of random key generation. The study investigated 50 hospital and primary health care centres in Alimosho Local Government Area of Lagos State to assess the level of digitalization of medical records which directly impacts on data privacy and security. The proposed system is evaluated using the ISO 25010 usability model which analyses eight (8) various constructs which are functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability and portability. Based on these constructs, a questionnaire will be designed and distributed for hospital review on the proposed system and the results will be analysed with the help of SPSS software. It was discovered that large number of hospitals and primary healthcare centres are not digitize raising great concerns on the implementation of data security in treatment centres. The overall results should show that the proposed system has a good usability rating which ultimately implies that it can be utilized in a healthcare organization for safe record management and secure file transfer and future recommendation for EMR as Cloud-native application.
