AaYusH: A Smart Contract-Based Telesurgery System for Healthcare 4.0

Telesurgery (TS) with 5G-enabled Tactile Internet (TI) has enormous potential to deliver real-time ultra-responsive surgical services remotely with high quality and accuracy. It is quite beneficial for society in the prospect of highly precise surgical diagnosis. However, the existing TS systems have security, privacy, latency, and blockchain (BC) storage cost issues, which restricts its applicability in surgical procedures across the world in the near future. To mitigate the above-mentioned issues, in this paper, we propose an approach named AaYusH (Ethereum smart contract (ESC) and IPFS-based TS system). The security and privacy issues in AaYusH can be resolved through ESC, whereas storage cost issues with the InterPlanetary File System (IPFS) protocol. Moreover, we present a real-time SC written in Solidity and deployed in Truffle suite. We test the security bugs of AaYusH in MyThril open-source tool and detect no issues. Finally, we evaluate the performance of AaYusH in context to latency and data storage cost, and it outperforms as compared to the traditional telesurgery system.
