Blockchain based Secured Telecare Medical Record Management: A System Design

Remote healthcare is very necessary in current pandemic times. Telecare empowered remote healthcare but mostly healthcare organizations manage telehealth information in centralized systems which are prone to various cybercrimes like ransomware, DDOS etc. Privacy and security of sensitive telehealth data is essential to ensure improvement in patient health. Blockchain technology in integration with wearable fitness technology has potential of securing telehealth records due to its unique characteristics like tracking, collusion resistance, transaction visibility, tamperproof and provenance. The aim of this work is to develop Telecare medical record(TMR) management system for uploading and retrieval of real time fitness monitoring and medication data using blockchain technology and smart healthcare ‘devices. Developed system permits healthcare providers to achieve fast access to fitness tracking data of patient in order to prescribe suitable medication over blockchain network. The system also keep track of all past TMR records that patients can access anytime in future. This system can prove to be a very beneficial mechanism to secure telehealth in current pandemic time. In designed system, unique IDs are computed for each TMR by universally unique identifier(UUID) and the hash generation of each TMR block is performed using secure hash algorithm(SHA)-256. The designed model comprises four building modules which are TMR uploading, TMR mining, TMR addition and TMR retrieval. All four modules of the developed prototype are tested and few execution outcomes are illustrated in the result section. Execution results shows that developed system is appropriate in TMR management for better health outcomes.
