Blockchain technology is increasingly recognised for its potential to enhance the security, reliability, and resilience of distributed systems. By ensuring data integrity and protecting against unauthorised access, blockchain creates immutable and transparent records, making it an appealing option for various applications. In the current healthcare landscape, secure data sharing is essential for improving patient outcomes, streamlining healthcare operations, and ensuring compliance with legal standards. This paper conducts a systematic literature review to explore how blockchain can be utilised as a security solution for health data sharing. We assess the strengths and weaknesses of blockchain-based solutions in areas such as secure data management, data sharing, access control, trust and transparency, and authentication and authorisation. Our findings indicate that blockchain has significant potential to secure health data sharing, although we identify certain limitations in blockchain-based access control systems and propose potential solutions. Additionally, this paper provides detailed insights into future research directions in this domain.
