With the advances in Information Technology, many healthcare organizations have converted conventional paper-based health records into Electronic Health Records (EHRs). It consists of digitized information of patients' personal data, health data and health records. The digitized health data includes disease details, treatment history, prescriptions, drug summary, microbiological test reports and other imaging reports. The large amount of EHRs and extensive use of healthcare technologies in the big data era increase the role of the Internet and cloud network to store a large amount of health data and facilitate its access across the Network. The insecure nature of Internetwork, third-party maintenance with poor access to data and financial burdens besides privacy breaches lead to several attacks. Considering the vulnerable nature of Internetworking, there is a requirement for an immediate and effective mechanism that facilitates storage, security, sharing and accessing of health data across various stakeholders. Indeed a secured Patient Centric EHR management system is essential for managing the exponential growth in health records.
