Contrastive Analysis of Healthcare Management System Using Different Use Cases Based on Blockchain Technology

The distributed, decentralized and secure network based Blockchain technology is used to store information about the patients in the medical field with patient centric control option. This information is spread out among many nodes and can’t be easily altered. There are different levels of how complicated patient information can be, like in the case of Covid19. Only authorized doctors or staff can safely access this information for treatment reasons with the patient’s permission. People outside of the patient’s care team can decrypt the information for treatment or advise, but only they can see it. Along with the use of blockchain technology in medicine, new technologies like IPFS and IoT have been introduced to make things safer, more efficient, and easier to remember. Security, authentication, data collection, and the sharing of encrypted medical information all need to be improved, though. As part of a suggested review, papers would be compared based on platform, programming language, system application, consensus algorithm, key findings and tools used, which would included from different studies based on the use cases and challenges in blockchain based Electronic health record(EHR) management system along with the issues raised.
