Empowering Health Systems: A Secure Approach to EHR Management
Vidyotma Thakur, A K Verma, Surjit Singh · 2025
Electronic Health Records (EHRs) are now a necessary component of contemporary healthcare, but managing them presents a number of security, privacy, and interoperability issues. In order to solve these issues, this study introduces a unique framework for EHR management that combines four cutting-edge technologies: blockchain, Zero-Knowledge Proofs (ZKP), Ciphertext-Policy Attribute-Based Encryption (CP-ABE), and InterPlanetary File System (IPFS). Our solution makes use of the Ethereum blockchain for transparent and safe record-keeping, IPFS for efficient and decentralized data storage, CP-ABE for fine-grained access control, and ZKP for private authentication. We offer computational proofs for important components together with a thorough security analysis utilizing formal verification tools like ProVerif and Tamarin Prover. Comparing our framework to other alternatives, the findings show that it provides stronger security guarantees, better privacy protection, and increased scalability. Our approach also defends against a broader variety of possible threats, such as man-inthe-middle attack, repudiation attacks, and side-channel attacks. This work opens the door for more effective and patient-cantered healthcare information systems by advancing secure and privacy-preserving EHR management.
