Abstract: The rapid digitalization of healthcare systems has amplified both the utility and vulnerability of Electronic Health Records (EHRs). Centralized EHR architectures remain susceptible to data breaches, unauthorized access, and transparency deficits that undermine patient privacy and regulatory compliance. This paper presents SecureChain-EHR, a comprehensive blockchain-based framework that addresses these challenges through an integrated multi-layer security architecture combining novel cryptographic and consensus innovations.The framework introduces the Hybrid Federated Proof-of-Stake (HFPoS) consensus mechanism, which merges federated Byzantine agreement with stake-weighted validator selection, achieving deterministic block finality under 50 milliseconds for 1,000 patient peers while reducing memory consumption by 57.4% compared to Proof-of-Work. Authentication employs dual-signature verification combining Modified 3-Prime RSA — using a three-prime modulus n = p×q×r for enhanced factorization resistance — and secp256k1-based ECDSA, ensuring non-repudiation at the transaction level. Role-Based Access Control (RBAC) is enforced through immutable Solidity smart contracts encoding role–permission mappings for four stakeholder roles: patient, physician, hospital administrator, and auditor. All medical records are encrypted using AES-256-GCM and stored off-chain in an IPFS distributed file system, with only cryptographic content identifiers and SHA-256 hashes stored on-chain — reducing on-chain storage overhead by 94% while preserving full auditability. Patient consent is modeled as a time-bound binary function enforced and revocable through smart contract logic.The system is architected across six functional layers: User Interface & Interaction, Data Processing & Transformation, Consensus & Validation, Smart Contract & Access Control, Blockchain Network & Storage, and Integration & Service Layer. Each layer contributes independently to security, processing efficiency, and regulatory compliance with HIPAA and GDPR standards. The Data Processing layer achieves the highest throughput of 140 tx/sec with a 95% security score, while the Smart Contract layer attains 99% unauthorized access prevention.The proposed framework establishes a clinically deployable,cryptographically sound, and scalable infrastructure for next-generation health information systems, enabling trusted multi-stakeholder EHR sharing while resolving fundamental limitations of both centralized and existing blockchain-based architectures.
