A Secure Design of Healthcare System with Blockchain and Internet of Things (IoT)

Health is one of the most important aspects of human life. For a healthy society, the healthcare sector must be reliable and efficient as much as possible. Blockchain networks can be used to provide innovative solutions to store and share patient data among hospitals, pharmaceutical companies, diagnostic labs, and physicians. Blockchain applications are capable of building trust and detecting fatal errors in the sharing of data. So blockchain can help in the security, effectiveness, and transparency of sharing medical data in the healthcare industry. Using this technology, medical institutions can get quality and trustworthy knowledge which they can use to improve the analysis of patient data and help in the good diagnosis of health issues. A thorough study and analysis have been done to explore the opportunities that blockchain technology can provide to improve the healthcare industry. The various characteristics, methods, and smooth workflow processes of blockchain technology are discussed in diagrams as a potential means of improving global healthcare. The article concludes by listing and analyzing various significant blockchain applications for the healthcare industry. It can help in implementing the smart contract, nonce concepts, and P2P distributed ledgers which ensure the immutability of the shared data. The methods discussed in this paper improve the security of Electronic Health Records (EHRs). The data of patients are taken directly via IoT devices which are used as medical instruments for patients which increases the reliability of data as there is no human interference in between hence human error is eliminated. The proposed technique implementation results show that the security of data has increased and it is more efficient.
