This study explores an innovative blockchain-based architecture to enhance patient data access traceability through the use of smart contracts. The primary objective is to ensure secure and transparent access management by immutably recording every interaction on the blockchain. By identifying key challenges related to security, privacy, and access control in medical data management, this research proposes a smart contract-driven approach to automate authorization processes. Smart contracts enable programmable access control while ensuring data integrity through their immutability. To address challenges such as scalability, performance, and interoperability, this work considers integrating complementary technologies and continuously optimizing system efficiency. This study establishes a solid foundation for developing and implementing pilot projects in the healthcare sector. By promoting secure and traceable data management, this approach aims to strengthen trust among healthcare stakeholders while enhancing patient care quality and data protection.
