Simulation of the Lightweight Blockchain Technique Based on Privacy and Security for Healthcare Data for the Cloud System

1. Introduction

With an increasing amount of technological advancements being introduced around the world, health care and biomedicine have always been a major concern to be improved in every possible manner. In order to enhance health care services, trust, procedures, and efficiency, and provide qualified nutrition and care to patients are of primary importance. Currently, the world is seeing more people putting off taking care of their personal health until a major hardship occurs. This is often linked to a person's over engagement to their lifestyle and accustomed busy schedule. Almost everything that is connected to the internet today performs data and access transfer through the Internet of Things (IoT). In the healthcare sector, IoT has also performed well by simplifying diagnostic procedures and ensuring more efficient monitoring of patients. As a result, IoT has revolutionized and disrupted nearly every industry that exists today, from education to supply chain management.

The challenges of adopting Blockchain in IoT

Blockchain technology coupled with IoT devices that have limited power and storage capacity creates complexity, including high computing costs and delays. The experiments adopted of blockchain model in IOT application are mentioned in figure 1. The healthcare Data types and their different type of healthcare data types are classified in figure 2, as well as the organizations that store, manage, and utilize them. It is clear that healthcare data extends beyond medical diagnosis reports and personal health information and the data pertains to health.
