Model of a decentralised medical card exchange system based on blockchain technology

In the current era of digitalisation, data protection is emerging as a critical issue across many industries, particularly within the healthcare domain. Given the crucial importance of patient data, it is imperative to establish dependable systems to protect it. Unauthorised access can lead to potentially harmful exploitation. This paper examines the variable. The data security environment in the healthcare industry exposes the weaknesses of conventional storage solutions. This work proposes a conceptual framework for the system that facilitates the collection, storage, and exchange of electronic data (electronic health records, or EHR). The research analyses blockchain technology as an innovative method for addressing security issues in the transmission of sensitive medical information. The objective of this study is to guarantee a dependable flow of medical data between medical institutions and other participants; the objective is to improve the confidentiality, integrity, and availability of this data. We will achieve this objective by creating and implementing software components that offer secure platforms for medical information transmission through blockchain technology. The study centres on the development of technologies that enable the seamless transfer of medical information. Collaboration among healthcare professionals, experts, and patients is essential to guaranteeing the confidentiality, integrity, and availability of this data. This research focusses on the methodologies and technologies used in the design and development of software components. They are crucial for establishing and preserving secure systems for sending medical data. The aforementioned components include software specifically developed for encryption, authentication, and authorisation, as well as techniques to guarantee error tolerance and data restoration. Results. This work presents a decentralised system concept for the collection, storage, and exchange of Electronic Health Records (EHR). In conclusion. In the healthcare industry, the findings of this study underscore the revolutionary capacity of blockchain technology to rethink data security norms. The suggested paradigm establishes a safe, transparent, and efficient platform for the management of electronic health records (EHR). Not only does it increase the security and integrity of medical data, but it also greatly enhances the quality of medical care and has a positive impact on patient treatment results. As we progress, the use of decentralized systems leveraging blockchain technology in healthcare offers a highly promising trajectory. The resolution of intricate issues pertaining to data security and privacy is now underway, thereby facilitating progress. The aim is to establish a healthcare ecosystem that is both sustainable and focused on the needs of patients.
