Blockchain Implementation for Privacy preserving and securing the Healthcare data

The contemporary medical system has a significant inconsistency between privacy issues and health requirements. A Blockchain-based technique to hide medical information and keep it safe is proposed in this study. This will ensure the data is accessible and reliable to study reviews and patients. There is no permission given to uncover patients' private information without providing any explanations to the patients. This proposal would execute distributed consensus between patients and research institutions while they function using the PBFT algorithm. The paper will discuss the security and privacy concerns of the proposed scheme. The proposed work is less expensive than other current ideas in terms of time involved in its implementation, with 150 blocks in almost 60 minutes.
