Electronic health records (EHRs) are both important and sensitive since they store crucial data that is routinely shared across various parties, such as clinics, pharmacies, and medical practices. These health files require increased safety and confidentiality to prevent leakage or misuse by a third party. There have been instances where a security breach in a patient’s electronic medical records has occurred. Blockchain technology may be useful in providing privacy for these documents. The fundamental goal of the work mentioned in this article is to improve the security, privacy, management, and efficient sharing of medical records. In this study, we will present a complete assessment of several strategies for safeguarding EMR privacy using blockchain technology.
