A Novel Approach for Electronic Medical Records Based on NFT-EMR

Abstract

saving the patient medical record electronically is done via electronic medical records (EMRs) where all the patient-related information that consider private and sensitive is usually related to the treatment process, as well as the diagnoses process of a specific patient usually this information needs to be shared and re-submit by many peers doctors with each, In this paper, propose a novel approach for electronic medical records system using a non-fungible token (NFT) based on a customized permission blockchain built with secret sharing technology to reduce the key management overhead as well as provide a readable extension of the ledger to ensure it is easy to read and easy access from any type of computer. The system that uses NFT for electronic medical records (NFT-EMR) ensures easy access and guarantees availability, privacy, and security providing authority to the patient over his data as well as proof of ownership which is done using proof of secret shares and consistency this system can be used in real-world between hospitals and medical centers and within metaverse world. The NFT-ERM system was evaluated using the main evaluation factors used to evaluate blockchain and compared to the standard ERM system.
