Consent Based Access Control and Healthcare Data
summary
Claims a workable model called Consent Based Access Control (CBAC) that puts patients in charge of healthcare records by linking existing provincial IDs to decentralized identifiers and storing digitally signed consents in a wallet app. Uses public key cryptography, zero knowledge proofs for minimal disclosures, and a verifiable data registry (blockchain-style) for lookups. Demonstrates why data lives in nine siloed systems, cites “over a hundred” SSI platforms, shows confidentiality and availability improve while integrity remains unchanged, and discusses emergency/backdoor, guardianship, and non-digital-citizen edge cases.
