        abstract = {The increasing reliance on digital healthcare systems has intensified concerns regarding data security, privacy, and integrity in Electronic Health Record (EHR) management. Conventional centralized healthcare databases are susceptible to single-point failures, unauthorized data modification, and limited patient control over sensitive medical information. This paper presents the design and implementation of a prototype blockchain-based secure medical record system that integrates encrypted off-chain storage with on-chain integrity verification. The proposed framework utilizes Ethereum smart contracts to manage access permissions and store cryptographic hashes of medical records, while actual encrypted medical data is securely maintained in a cloud-based database. A distinctive feature of the system is the incorporation of family health history linking, enabling structured association of related patient records to support hereditary disease traceability without exposing confidential medical details. The hybrid architecture ensures scalability, enhanced security, and patient-controlled access while maintaining data integrity through blockchain validation. Experimental deployment on a public Ethereum test network demonstrates the feasibility and practical applicability of the proposed system for secure and decentralized healthcare data management.},
