Enhancing Healthcare with Blockchain: Innovations in Data Privacy, Security, and Interoperability

The rise of digital technologies has transformed the healthcare industry, enabling smarter and more efficient services. But high data volumes and reliance on centralized systems pose significant challenges, including real-time data sharing functionality and vulnerability to breaches. Blockchain technology offers flexible solutions for distributing data management and ensuring secure, transparent and immutable transactions. This paper explores the use of blockchain in healthcare, emphasizing its potential to improve data privacy, improve communication, and simplify the management of electronic health records (EHRs). Key features of the blockchain such as decentralization, immutability and cryptographic security have been analyzed in the context of healthcare. The review looks at notable developments, including blockchain-based frameworks for secure data shares, smart contracts for automated processes, and parallel healthcare systems combining it with artificial intelligence, as well as enabling efficiencies within the supply chain. This work provides a comprehensive analysis of blockchain's transformative potential and identifies areas for further research to ensure that it has been widely accepted.
