Blockchain-Powered Smart Contracts for Secure and Transparent Healthcare Systems

Abstract

As the healthcare systems become more digital, a problem of data security, patient information safety, and the methods of guaranteeing that the information is available to everyone has come to the fore. Role-Based Access Control (RBAC) and other crude mechanisms of determining who is allowed to access what data are limited in preventing breaches and unlawful manipulation of data. To address these issues, this paper will propose the use of blockchain-based technology to develop a smart contract architecture that would enhance the process of managing healthcare data in a more transparent and secure way. The solution offered is based on the programmable smart contracts and the blockchain technology that cannot be altered and is decentralized to ensure that audits can be performed, data integrity is ensured, and access control is configured. According to simulated deployment studies, the proposed plan is much better than the current designs in the deterrence of unauthorized access, reduction of data modification and reducing the cost of operation.
