Abstract: Blockchain technology is known for its decentralized and immutable nature, which makes it highly resistant to hacking and unauthorized access. This would ensure that patients' private health information remains secure and protected from potential breaches. Moreover, the use of blockchain can also enhance data integrity by creating a transparent and tamper-proof record of all health updates, further increasing trust in the systems. The COVID-19 epidemic has made human health one of the most crucial things we should focus on more in our day-to-day lives. Social separation could help contain the COVID-19 pandemic. Humans are therefore urged to avoid physical contact with one another if the condition is permitted. It is suggested that medical professionals use the Internet of Things (IoT)-based Health Monitoring Application to keep an eye on their patients via their mobile devices. With the help of the suggested system, patients can update the system with their daily health status, and medical professionals can use their mobile devices to monitor their patients for future health policy. Because the suggested system is an application that users can access from their mobile devices rather than just using a laptop or computer to browse the website, it is more practical than most of the current system. Patients do not need to visit the hospital for a check-up because they can update the system with their health information. If physicians discover unusual symptoms in a patient's medical record, are they obligated to seek medical attention? Furthermore, private health information is regarded as confidential. Consequently, this would examine the risks associated with the backend system of the suggested solution as well as security threats. Additionally, by utilizing blockchain technology, improvements in security and privacy can be achieved.
