Securing Vaccination Data Using Self-Sovereign Identity, Hyperledger Fabric and Zero Trust Model

People of all ages need a variety of vaccines to avoid spreading preventable diseases. For future reference and analysis, vaccination information must be stored maintaining proper security in a Vaccination Data Management (VDM) system. In this paper, a secured data preserving framework is proposed using the Self-Sovereign Identity Management (SSIM), Hyperledger Fabric and Zero Trust Model (ZTM). SSIM is used for sharing secured data following authentication, integrity verification and control using digital identity. Besides, a proof-of-concept is added using Hyperledger Fabric platform as a permissioned blockchain which operates on a distributed network and can only be accessed by valid users. ZTM features are incorporated with this proposed model to enhance security better than the other existing data securing frameworks.
