A
blockchain-based
system and method for secure and auditable sharing of medical image studies between providers, patients, and authorized recipients. The
system has modules for verifying identities of trusted healthcare providers as issuers of medical data, managing secure storage of medical images and
metadata, minting non- fungible tokens (NFTs) representing patient ownership of studies, authenticating patient consent for
data sharing, and controlling access to shared data by authorized parties. Issuer registration authenticates healthcare providers permitted to submit studies by verifying credentials against authoritative sources. Secure
data management employs cryptographic wallets and smart contracts to ensure only verified issuers can create new medical data NFTs on the
blockchain. Automated
processing extracts medical data such as image files and
metadata upon upload for separate secure storage, with
metadata references encrypted in the associated NFT.
