BHAS: A Blockchain-Based Healthcare Analytic System to Manage Privacy and Scalability Concerns

Keeping patient records with diagnostics details is the main aim of digitalized healthcare but health data in traditional storage systems will always attract a risk to data security. There is a high risk of data leak if adequate measurement is not obtained, intruders can modify or delete any of the records. Blockchain is a stable technology that will be helpful in the development of a secure yet tamper-resistant system for the management of data. However, setting up an all-new system based on blockchain that will replace the existing system is quite expensive and sometimes time-consuming. But to get an ultimate and temper- proof system in the proposed architecture, introduce a smart contract with a layered approached integration mechanism, named the blockchain PHR (Patient Health Recorder), Migrating the existing cloud-basis system of health records to a public yet secure blockchain infrastructure to develop a tamper-resistant managing system of the health record
