A Secured Blockchain Database Management Model for Medical Based Organization

The implementation of an Electronic Health Record (EHR) management system has proven to be an effective alternative to the traditional manual method of handling medical records. However, concerns about data privacy and security persist in the healthcare sector, particularly due to the outdated centralized database systems that have failed to meet modern expectations.To address this, a secured blockchain database management model for medical based organization is designed for healthcare organizations, emphasizing a patientcentered approach. This model efficiently handles and maintains individuals’ health records using blockchain technology. Developed based on object oriented analysis and design methodology, the system was built using Visual Studio Code (VS Code), PHP, the Ethereum network, Web3.js, and Ganache.Blockchain technology provides the foundation for decentralizing patient information and ensuring secured data storage. Smart contracts arecritical in protecting patient privacy and data integrity by facilitating secured transactions, each modification is verifiable and propagated across the network. To further enhance the model’s security and integrity, a cryptocurrency wallet such as MetaMask is integrated, offering a centralized yet secure repository for medical records that authorized users like patients and healthcare providers can access anytime.By providing a robust platform for securely managing data with customizable access permissions and enabling the safe exchange of patient records, this blockchainbased system surpasses legacy systems in efficiency, reliability, and accessibility in the healthcare domain
