Abstract

As Electronic Health Records (EHRs) become integral to modern healthcare, concerns regarding security, privacy, and scalability have emerged. Conventional centralized systems face vulnerabilities and lack patient data control, necessitating innovative decentralized solutions. This research introduces a novel AI-blockchain-based architecture for permissioned health networks, leveraging zero-knowledge succinct, non-interactive arguments of knowledge (zkSNARKs). The framework integrates AI-blockchain, InterPlanetary File System (IPFS), and zkSNARKs to enhance EHR security, privacy, and scalability. IPFS is employed for off-chain storage, improving scalability alongside blockchain's tamper-proof logging. Encryption and smart contract-based access controls preserve privacy.
