An Overview of Distributed Computing in the Cloud and BlockChain for Safeguarding the Healthcare Sector

Abstract

The need for patient-centered electronic records that can store and retrieve the myriad details of a patient's medical history as documented during treatment has increased dramatically.These records are vital for future care, billing, or treatment.The distributed ledger technology known as Blockchain enables us to store this data and start and enable use at lightning speed while keeping the system transparent and secure.Using a distributed system with ledger capability allows for the safe and interoperable storage of records.With the elimination of mediators in financial and data transactions and in verifying data authenticity and ownership records, blockchain technology promises to alter the current state of digital asset transactions radically.Its extensive files and easy access to patients' medical histories are two of the most critical issues in healthcare, and its immutability, decentralization, and openness make it an ideal solution.Interoperability, the ability of various health organizations and software product makers to connect and exchange data securely and smoothly, is crucial to healthcare systems' practical and successful operation.Lack of interoperability is the root cause of many difficulties in contemporary healthcare, including data silos and disparate workflow tools.To solve this problem, a system that allows safe, recognized medical records to be kept in separate databases should be implemented.Using fog computing, which can decentralize data processing and handle massive amounts of data, we reviewed the literature and performed a system overview of blockchain technology in this study.Our ongoing experimental study highlights areas where current systems are lacking and suggests potential avenues for further research.
