Blockchain-Based Secure Data Sharing Framework For Healthcare Information Systems

David Williams, Jessica Taylor, William Thompson,

Abstract

Health information systems face major challenges in terms of data security and integrity. This article proposes a blockchain-based framework that enables secure data sharing among various entities in a health information system. The framework ensures the confidentiality, integrity, and transparency of patient data through the use of smart contract technology and hash-based encryption. Case studies on several hospitals demonstrate improved data security without sacrificing system efficiency.
