Significance and Challenges in Blockchain-Based Secure Sharing of Healthcare Data

Both service providers and patients require healthcare information. Electronic Healthcare Records (EHR) must be shared and maintained in a more secure manner. Blockchain technology has the potential to address many of the issues confronting the healthcare industry, including electronic health record security and privacy (EHRs). Blockchain technology, with its decentralised and transparent ledger, can provide a secure and efficient platform for healthcare data sharing and management. This can help to improve the privacy and security of patient data, the efficiency of healthcare processes, and the ability of healthcare providers to collaborate more effectively. However, issues such as interoperability, scalability, regulation, governance, and security must still be addressed. This article offers a summary of the potential benefits and challenges of blockchain technology in healthcare, with a particular emphasis on EHR security and privacy. It investigates the various blockchain-based models that can be used to secure EHRs, such as public, private, hybrid, and federated models, and discusses the key challenges that must be overcome to ensure the successful implementation of blockchain-based EHRs. While challenges remain, the sustained development and adoption of blockchain-based solutions in healthcare has enormous potential for getting better patient outcomes and transforming healthcare delivery.
