Hospital Information Systems (HIS) are now widely used in various medical institutions due to the rapid advancement of information technology. However, owing to the sensitivity of medical data, the data is usually managed solely by the relevant department of the institution, leaving patients and other departments unable to verify its integrity and authenticity. This unilateral data management by the department erodes the credi-bility of the data and complicates building trust between doctors and patients. To address this issue effectively, we propose a scheme of patient-controlled medical data auditing in institutions by leveraging blockchain technology. We establish a permissioned blockchain network among medical departments and program smart contracts that allow patients to authorize changes to their data to build trust in the data while maintaining patient ownership. More specifically, we propose different evidence on-chain strategies that can be adapted to meet various data integrity and recoverability requirements for different data characteristics. Additionally, we present an adaptive hash method that ensures outstanding computational efficiency across a wide range of file sizes. Therefore, MeDA enables patient-controlled data auditing within the medical institution, guaranteeing data integrity and authenticity. The analysis and evaluation demonstrate that the proposed strategies are able to audit various types of data securely and efficiently. |
