A review on FOG supported architecture in healthcare using blockchain

Abstract

Medical expenses are on the rise due to population growth and the prevalence of chronic diseases, which has led to the widespread adoption of technical solutions. A blockchain-based framework offers a decentralized network for tracking these records, enabling rapid adoption while maintaining transparency and security. The implementation of this distributed framework includes a ledger for securely storing records and supporting applications through interoperability. Blockchain technology eliminates the need for a centralized authority to verify information integrity and ownership, as well as mediate transactions and the exchange of digital assets. It also enables secure and confidential transactions and agreements among interacting nodes.Our study investigates both blockchain technology and the fog computing framework for distributed data processing, with cloud-based approaches used to store and process data generated by these solutions. The result is the fog computing model, which brings computational power and storage closer to data sources as a solution to this challenge. Managing medical data within the fog remains a complex task, requiring careful consideration of factors such as accessibility, performance, interoperability, and data protection. This article discusses a Fog Computing-based software architecture designed to simplify the management of medical records, addressing these issues effectively.
