Scalable and Security Framework to Secure and Maintain Healthcare Data using Blockchain Technology

The technological advent of Blockchain, Bigdata, Cloud, and AI made it easier to be stored and retrieved Electronic Health Record (EHR) data and then used it by patients, doctors, and research groups for treatments and analytics. Blockchain security ensures the security of patients' records data with smart contracts due to the most reliable and secure platform for many industries such as finance, IoT, healthcare, and logistics management. The innovative use of smart contracts in the healthcare industry enables a secure system to provide privacy and complete protection with patients' record data and to be able to integrate with various entities in the healthcare sector. The criticality of acquiring, storing, and securing EHR is essential in the healthcare industry to provide faster services. Integrating EHR data with multiple healthcare providers accrues various benefits such as quick insurance approvals and dealing with emergencies and critical situations. It expedites medical records access to patients, doctors, insurance companies, primary healthcare providers, pharmaceuticals, and laboratories to reap healthcare benefits efficiently. The challenges with EHR data are security and storage, which can be addressed with Blockchain security, and integrating it with Bigdata provides huge benefits of data storage, scalability, and performance to store and maintain data efficiently. Often acquiring, storing, securing, and maintaining healthcare data involves excessive administrative and operative costs. Most of the research work is done on Blockchain technology frameworks and implementation but the most critical part of data storage and maintenance is yet to be focused area, as how to manage this data in the long term. This paper intends to research the best Blockchain based architectural framework to store EHR data in Bigdata storage systems at a lesser cost compared to other Infrastructure facilities by utilizing inexpensive hardware grouped into clusters and assigned resources to share across the network and easy to maintain even after procuring the data across the entities securely.
