Development of A Robust Privacy Enhancing Data-Sharing Framework for Healthcare System Based on Decentralized Control

Abstract

Blockchain technology enables decentralized, immutable, verifiable digital asset transaction records. Any interested party can access these documents. Affected industries include healthcare. The use of Electronic health records raises security concerns. Blockchain technology could secure this sensitive data. Transaction relatability, crypto-key control, and on-chain data privacy are security and scalability challenges for blockchains. Blockchains confront scalability and security issues (e.g., adhering to privacy legislation). Many researchers have developed different frameworks to preserve their privacy and control their ledger data. Moreover, existing work based on blockchain addresses the crypto-privacy issues. In this article, the proposed design and a thorough discussion are provided on the current state of blockchain-based healthcare systems.
