A BLOCK CHAIN BASED SOLUTION FOR DIGITAL TWIN FOR MEDICAL USE

Abstract

The health problems of this world's population are universal. Nowadays, protecting one's personal 
medical information is a priority for everyone. No one likes to let people in on their vulnerabilities. Electronic 
health records (EHR) were developed as a solution to this issue. However, a number of experts have pointed 
out that there are drawbacks to EHR that patients should be aware of.In this study, we will explore how 
blockchain technology may replace EHR and other healthcare record keeping methods. A blockchain is a 
distributed ledger in which each transaction is represented by a hash value and each block contains a reference 
to the block before it. As use of blockchain technology in the healthcare industry grows. Blockchain ensures 
the confidentiality, availability, auditability, and manageability of health records. People's health data in 
particular lacks trustworthiness, centralization, and transparency, which raises questions about the distinction 
between "external" health data and "internal" health data. This is a significant stumbling block in the expansion 
of healthcare in many countries. However, they all suffer from what we term a lack of data care and 
refurbishment. Health care data should be as open and decentralised as feasible. Moreover, the same data must 
be used as the ready-to-use source of information for governments to take immediate action if there is a 
possibility of an outbreak, lack of medication and equipment, vaccination and clinic drives, and many other 
probable problems faced by certain locality encompassing the health institutes. A solid middle ground linking 
individuals, communities, and national healthcare systems was what was really lacking. To do this, we 
implement this system.
