NFT-based online prescription for data management in healthcare services

Abstract

ABSTRACT The development of electronic health (e-health) systems in the last decades led to the emergence of effective infrastructures for managing health records. Due to the vitality and massive amount of healthcare records, blockchain is considered one of the most important infrastructures to store and exchange health records. Access to patient’s medical histories and health record management are essential to healthcare systems. Patients’ records must be exchanged among various parts of the healthcare system and users should have access to manage their profiles and use online facilities in a secure manner. In this paper, for the first time, the non-fungible token (NFT), which is a nascent technology, is used to certify the information immutability of healthcare records in the blockchain infrastructure. The ownership of property and prevention of information disclosure is guaranteed using the encryption strategy is used in the proposed NFT technology. Furthermore, the proposed model satisfies all security criteria such as data integrity, non-repudiation, anonymity, confidentially and privacy. As a result, the proposed model outperforms the related research in the healthcare domain. The proposed model brings many facilities for both patients and physicians such as secure accessibility, data quality, patient consent, efficient record management and better availability and reliability.
