Secure Healthcare Data Sharing Ecosystems over Blockchain

Abstract

In the present day's digital world, when privacy, accuracy & quick access to patient information directly affect medical outcomes, the safe & effective sharing of healthcare information has become a major issue. Even while these centralized data management systems are very common, they frequently run into many problems including data silos, poor interoperability & being vulnerable to these breaches or unauthorized access. These restrictions make it harder for healthcare providers, patients & researchers to work together, and they also hurt the confidence and integrity of their information. Blockchain technology offers a decentralized and unchangeable system that ensures their transparency, security, and smooth data flow amongst all parties involved in order to solve these problems. This research introduces a blockchain-based structure for the exchange of healthcare data, using distributed ledger technology to provide secure access control, immutable audit trails & interoperability across electronic health record (EHR) systems via the use of smart contracts. The framework uses a permissioned blockchain architecture to balance privacy as well as scalability. This lets healthcare companies keep ownership of their information while allowing controlled data sharing. A case study shows that the proposed technique greatly enhances data security, makes it easier for administrators to conduct their jobs & makes it easier to handle patient consent compared to other methods. Also, the blockchain-based technology makes it easier to track their information and build trust amongst stakeholders, which leads to a more open & cooperative healthcare environment. The results show that implementing blockchain to healthcare systems decreases data-associated risks and supports the development of patient-oriented, interoperable, and ethically sound health data infrastructures that could influence how healthcare is administered throughout the entire globe.
