PATIENT-EMPOWERED DATA MANAGEMENT HAVING A SECURE BLOCKCHAIN ARCHITECTURE WITH DECENTRALIZED OWNERSHIP

Absstract of: US2025265365A1

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. The system generates patient-controlled wallets for managing ownership of their medical NFTs without separate identity verification. Patient consent for sharing data is authenticated through multi-signature wallets requiring patient approval before minting study NFTs. Controlled access for other parties is gated by cryptographic proofs of authorization without exposing data. The immutable blockchain ledger records all sharing transactions initiated through patient and provider wallets, providing transparency and an audit
