A Review on Smart Healthcare System using Blockchain Technology

Almost in every space of life, the IoT (Internet of Things) entered its source. The most significant domains are smart healthcare that widely utilizes IoT solutions and frameworks. When we use the cell phones and wearable devices, then healthcare domain will be massively enhanced by IoT-based smart healthcare systems. For accurate, improved, and timely diagnosis, the cell phones and wearable devices conduct a considerable utilization of health data sharing. For many security breaks and different harmful attacks, smart healthcare systems are profoundly vulnerable against these problems such as forgery, privacy leakage, tempering and so on. With the passage of time, the blockchain innovation arose as a hopeful arrangement against such breaks and difficulties. In this survey paper we discuss about a modern study on various difficulties and issues that were occur in small healthcare system because of the traditional methods of security measures and also we found solution of these problems in blockchain. We also discuss the benefits of these solutions and important security requirements of the smart healthcare system.
