Blockchain for Secure and Transparent Healthcare Data Sharing Across Platforms

Platform healthcare data interoperability is plagued by privacy, security, and transparency issues. With the advent of digital transformation, blockchain technology could solve such problems by using a decentralised and irreversible healthcare data ledger. This study discusses securely and transparently sharing healthcare data using blockchain. It examines how the blockchain might improve healthcare system interoperability, data integrity, patient privacy, and autonomy. It tests the blockchain system using publicly available healthcare data such health records, patient demographics, and clinical data in simulated care environments. Pandas and Matplotlib are Python-based tools for data processing and visualisation. The article critically reviews blockchain technology in healthcare literature, identifies its pros and cons, and proposes a blockchain-based architecture for safe information transmission among systems. A case study verifies the architecture's viability and benefits. Blockchain technology could improve healthcare data security, patient trust, and operational efficiency, according to the study. We also solve scalability, regulatory, and integration issues. The study suggests that healthcare practitioners, technology developers, and regulatory agencies must constantly innovate and collaborate to maximise blockchain's healthcare data sharing potential.
