A conceptual distributed framework for improved and secured healthcare system

ABSTRACT In the twenty-first century, healthcare information technology has created the ability to electronically store, maintain, and move data across the world in a matter of seconds. It allows each healthcare provider to possess its own database of patient’s electronic medical record (EMR). The concept of ‘big data’ is now treated from different points of view covering its implications in many fields, including the healthcare sector. To achieve the wealth of health information, integrating, sharing, and availing data are the essential tasks that ultimately demand the concept of a distributed system. However, privacy and security of data are the matter of concerns, as data need to be accessed from various locations and users in the distributed system. The purposes of the present study are to provide an overview of big data and the effectiveness of big data in healthcare and to introduce a secured distributed e-healthcare system to provide better and secured health services across the nation.
