Block Chain based Secured Wireless Patient Health Monitoring System

The patient health monitoring approach based on the Internet of Things (IoT) consists of smart electronic devices and protocol that communicate to the data via the internet. The medical field now has countless new avenues to explore because of this discovery. Health information and additional symptom information can be gathered by associated smart sensors. This allows the patient to reach the right healthcare specialist, thus facilitating distant care. However, there are concerns about hacking and confidentiality of medical data in IoT platforms. As a result, it is crucial to develop specific safety protocols for IoT-based patient health monitoring system. Researchers periodically propose a new strategy for protecting data collected by IoT-based healthcare devices. The data can be vulnerable to numerous forms of attacks. Thus, the researchers proposed the notion of enhancing the security of the IoT-based patient health monitoring system by incorporating blockchain technology. This research study suggests a Blockchain-based XOR Elliptic Curve Cryptography (XORECC) method for securing an IoT healthcare monitoring system against a wide range of possible attacks. The proposed method is evaluated against the traditional approaches like Advanced Encryption Standard (AES) and Rivest-Shamir-Adleman (RSA). The experimental findings confirm that the suggested approach provides a very high level of security for data transmission over the IoT.
