Security Enhancements in M-Health Using Distributed Ledger Technology based Digital Locker System

Abstract Electronic Medical Records (E.M.Rs) comprise sensitive and private information of the patients in m-healthcare, and the passing of data across different medical institutions poses severe challenges. Leakage of information could destroy the privacy of the data, and the availability of the data at runtime may be disrupted by the DDoS (Distributed Denial of Service) attack. Distributed Ledger Technology (DLT) helps overcome the challenges of the trusted decentralized database. It is possible to validate all the stakeholders by a single-step authentication process using distributed ledger technology. In this research paper, the authors have proposed a distributed ledger technology architecture (DLTA) using an m-health digital locker (DL) system and presented the interaction of the different m-healthcare entities with the anticipated model. The authors have designed the mathematical model to enhance the security re-assurance of the DLTA-based m-health DL system. The security analysis of the proposed model is highlighted and compared the same with the non-distributed system architecture. The key factors considered for evaluating the proposed model are network congestion, throughput, average turnaround time, average response time, average waiting time, and network consumption.
