A Healthcare Data Management System on Blockchain Framework

Abstract

Blockchain is a distributed ledger technology that is commonly employed in the development of new digital currencies. Many new successes in industry and academia have resulted from the rapid development of blockchain technology. This architecture is currently widely employed in e-finance as a generally acknowledged electronic money. It has crucial qualities like immutability, decentralization, and transparency that could help with critical healthcare challenges also. These issues may include incomplete records at the point of care, restricted access to patients’ own health information, etc. Multiple copies of a single data are stored in various locations and on several devices of a blockchain architecture. In spite of lose or damage of one copy of data, multiple copies remain safe and secure. The connection between the blocks prevents any of the information from being modified or a block from being put between two existing blocks. In this paper, a healthcare data management system based on blockchain technology has been proposed. The proposed model is a multilayer architecture where different entities related to healthcare system will be different components. The entities are patients, doctors, clinic or hospitals, medical records etc. Effective medical data sharing is one of the important aspect of this research work.
