A lightweight blockchain-based framework for medical cyber-physical system

Abstract

A medical cyber physical system(MCPS) combines intelligent medical devices with a network. Nowadays, MCPS is extensively used in the healthcare system. While sharing the patient data into MCPS, the data privacy of the MCPS is a significant challenge in healthcare as most of the devices are suffered from data leaking and data manipulation attack. In this current work, blockchain implementation ensures patient data security and privacy with no delay. The blockchain module controls unauthorized data access from illegitimate users. The result and performance analysis of the proposed framework shows the low latency in the data sharing, high transaction rate, and high throughput with an increasing number of users in the network.

Blockchain-Enabled Hyperledger Fabric to Secure Data Transfer Mechanism for Medical Cyber-Physical System: Overview, Issues, and Challenges

“…Cyber-physical systems (CPS) are an architectural paradigm that provides several benefits to the economy and society by combining pervasive sensing and communication technologies. The term "cyber-physical system" (or "cyber-sys") refers to a system that has been specifically built to include cyber components, such as computers and networks, within a traditional physical system or process [1]. These parts are remarkably intertwined, suggesting that the proper operation of one part is crucial to that of the other.…”
