A Review on Integrating Cloud Blockchain Technology to Secure Electronic Health Records

Abstract

The increasing adoption of electronic health records (EHRs) has necessitated secure and efficient sharing mechanisms among healthcare institutions. However, challenges related to data integrity and privacy persist. This review study explores the potential of blockchain technology to address these challenges and enhance EHR sharing security. Blockchain offers several advantages, including immutability, transparency, and decentralization, which can significantly improve data integrity and prevent unauthorized access. Consensus algorithms like Proof-of-Work (PoW) or Proof-of-Stake (PoS) ensure data accuracy and reliability. Moreover, blockchain facilitates secure and efficient data sharing by eliminating intermediaries. Smart contracts automate processes, reducing human error and improving efficiency. Additionally, blockchain provides a transparent audit trail for tracking data access and usage. While implementing blockchain in EHR sharing systems presents challenges like scalability, performance, and regulatory compliance, careful consideration of consensus algorithms, data privacy measures, and integration with existing systems is crucial. Blockchain's potential to enhance EHR sharing security and contribute to a more efficient healthcare ecosystem makes it a promising solution.
