What is it about?

This paper implements a distributed application for healthcare systems with IoT devices to improve security and privacy features using blockchain technology. The front-end part of the proposed distributed application provides the user interface. Here, the users or patients can use a unique ID to access their respective medical certificates. Therefore, they need not carry the medical certificate physically. As medical certificates are maintained using the blockchain structure, the users can access the certificate at any time and from any place. Furthermore, the proposed scheme prevents unauthorized access from hackers and malicious users

Why is it important?

The most common attacks that the healthcare sector experienced in the cloud are phishing, data theft, masquerade, and data breaches. As most healthcare data are communicated over the internet, the security and privacy issue of healthcare records is always a significant concern in the medical industry. In terms of those, the proposed scheme can provide the details of security analysis in terms of attacks prevented by the designed IoT and Blockchain architecture.

Perspectives

I hope this article can give good inspiration to people who want to make more efficient personal health care data protection. I hope that this paper will be a paper that can understand the concept of blockchain for those who are interested in personal data protection.
