A Survey on Decentralized e-health record with health insurance synchronization

In the medical field, electronic health records (EHR) serve a critical function that benefits both healthcare providers and patients. Many cloud-based solutions for medical record exchange have been offered, but the credibility of a third-party cloud service is questioned due to the centralized approach. As a result, a decentralized blockchain system for sharing electronic health records has been established that does not rely on third-party services. Existing services, on the other hand, exclusively collect data from medical tests. They are ineffective at sharing data streams that are continuously created by various sorts of devices. The information gathered is shared with laboratories and medical institutions for future research. Furthermore, current techniques are too rigid to accommodate metadata modification effectively. Decenrod proposes a medical data-sharing scheme that combines blockchain, electronic health records, and a structured peer-to-peer network based on InterPlanetary File System (IPFS) techniques to address the above efficiency issues in existing medical data-sharing and storage services. A session-based healthcare data-sharing strategy has been designed, according to Decenrod, which allows for more flexibility in data sharing. According to the evaluation results, Decenrod can improve efficiency and meet security criteria in data exchange by implementing Decentralized EHR. The information gathered is shared with laboratories and medical institutions for future research.
