Digital Identity Proposal for Unified Medical Record using Blockchain technology

Abstract:

This article describes the architecture of a Blockchain subsystem to manage access through Digital Identity to the Electronic Medical Record of patients. During this work, the agile programming methodology focused on Blockchain by Marchesi et al. [1], was followed. Therefore, the development of the work was divided into a section for the programming of the Blockchain network and another section for the development of the part of user interfaces. The Hyperledger Fabric framework was used to set up the Blockchain network due to its focus on Digital Identity management. In addition, the graphical interface in React was developed to allow communication with users. The whole development had a modular approach, where three modules are worked in both sections of the project: Identity Management, Authority, and Consortium of Health Service Providers. This architecture has managed to be developed and its process and functioning are presented in this work.
