Data Sharing and Privacy Preserving of Medical Records Using Block chain

Abstract

Because of privacy concerns and the fear that others may gain an advantage from the exchange of
information, transferring medical records from one facility to another has traditionally been a difficult
operation for the healthcare industry. This is changing, however.
Health care organisations are unable to get long-term patient information because of inconsistent
policies and permissions granted. When it comes to detecting medical conditions, the ability to share
electronic health records will aid in improving diagnostic accuracy. Blockchain technology is
recommended in this system in order to improve patient data security and prevent medical records
from being lost or manipulated. Block chain for healthcare is a method of securely sharing and
preserving medical records with other organisations without the risk of them being tampered with, and
the purpose of this survey is to learn more about how the technology works and how it may be used in
this context (smart contracts and concept of mining).
