Enhanced Proof of Authentication(E-PoA) Consensus Blockchain-Based Secured Health Care Data Transmission in Internet of Things

Blockchain and the Internet of Things (IoT) are revolutionizing healthcare, presenting the potential for transformation. The IoT is achieving more and more confidence as the infrastructure for future applications. Therefore, based on the comprehensive integration of Blockchain (BC) technology with IoT, security requirements are provided through security frameworks built into BC. Healthcare IoT applications in BC technology are revolutionizing industries. It also analyzes the potential benefits of BC implementation in IoT and healthcare for securely transferring medical data. Blockchain's decentralized and immutable nature of medical data sharing offers secure ways to store and transmit data. However, it is necessary to protect the data's privacy stored and shared securely. This review paper evaluates the algorithm based on Rivest, Shamir, and Adelman (RSA), Advanced Encryption Standard (AES), Lionized Golden Eagle-based Homomorphic Elapid Security (LGE-HES), and BC-Assisted Secure Data Management Framework (BSDMF). This survey paper describes Blockchain technology-based medical data transfer based on IoT medical systems. The performance evaluation regarding Root Mean Square Error (RMAE), MSE, time complexity, and security performance compared to standard technologies can be analyzed.
