Blockchain Enabled Electronics Medical System Proposed Framework with Research Directions

The upcoming industry is continuously changing, and the current systems and technologies are not suitable in their present form. They need to upgrade to solve the complex problems that are faced by the different applications. The healthcare industry is one of them. In the current healthcare industries, the patient's information is stored in the central cloud servers, and the third party (TP) is required to share these details among the service providers. As a result, sharing information without adopting TP in a distributed manner is a challenging task. The distributed ledger technology blockchain has the potential to resolve the problems mentioned above. The blockchain provides the immutability, transparency, and traceability of records where the records are distributed among the many nodes. This article first presents the various problems of the current electronic medical record (EMR) system, discusses the importance of blockchain in EMR systems, and finally summarizes the existing approaches with their future scopes. Based on it, this paper proposed a novel architecture for a blockchain-enabled secure sharing of health records. In addition to it, possible research directions with the relevant security attacks for blockchain systems are also highlighted in the paper.
