Healthcare Domain in IoT with Blockchain Based Security- A Researcher's Perspectives

The impact of Internet of Things (IoT) is most predominant and leading over the world. IoT is used to gather information/data from various sensors and other smart devices. The beneficiary of using technology of IoT can exchange information and enable to communicate with smart devices among themselves. In healthcare environment, IoT brings more convenient to doctors, nurses and patients. It can be more efficient for monitoring the illness patients and diagnosing very effective with reducing the cost. There are various security breaches and malignant attacks in healthcare system which are extremely vulnerable such as forgery, privacy leakage etc. Therefore these challenges and issues in security based on authentication and interoperability which bring to deteriorate. Recently, one of the key development in security is created by Blockchain (BC) technology which can exchange the data in secure manner. In many existing studies can be improved by enabling BC technology in the healthcare system. The main scope of BC technology has to convey effectively exchanging information between patient and other medical service parties based on some of the advantages such as authentication, immutability, decentralized storage, interoperability, distributed ledger, trustworthy and provides opportunity in a reliable manner and increase in productive. This paper presents challenges and problems for BC based IoT healthcare and provide with the security requirements of such domains due to traditional security measures. The aim of this paper is simply investigate how Blockchain will improve the healthcare environment within the IoT context. It also amalgamates the potential of blockchain technology as a promising security measure, highlights potential challenges in the healthcare domain, and provides an analysis of different blockchain based security solutions.
