A Conceptual Framework for Blockchain-based Intelligent Healthcare Data Management

Blockchain is a distributed ledger technology, frequently used in the creation of new digital currencies. The rapid development of blockchain technology has resulted in numerous new successes in industry and academia. This architecture is now widely used in e-finance as a widely accepted electronic money. It possesses critical characteristics such as immutability, decentralisation, and transparency, which may aid in the resolution of major healthcare challenges. Highlighted issues are like, incomplete treatment records, restricted access to patients’ own health records and so on. A blockchain architecture stores multiple copies of a single piece of data in various locations and on various devices. Hence, even if one copy of data is damaged or tampered, other copies remain immutable. The link between the blocks prevents any of the information from being changed or a new block from being placed between two existing blocks. A healthcare record management system based on blockchain technology is proposed in this paper. The proposed model is a multilayer architecture with different components representing various entities related to the healthcare system. Patients, doctors, clinics or hospitals, medical records, and so on are examples of entities. Effective sharing of medical data, ensuring Authentication and Authorization, is one of the most important aspects of this research.
