區塊鏈技術的出現在醫療數據共享方面產生了重大影響，特別是在由衛生機構控制的電子健康記錄（EHRs）共享方面。然而，本研究旨在提出一種在病患與衛生機構之間私下分享個人健康記錄（PHRs）的新方法，目的在於保留病患的數據所有權。為此，我們提出了一種名為 FHIRTerminalNode 的新系統，利用以太坊區塊鏈的智能合約功能，提供一個分享位置和加密信息的平台，從而促進醫療健康數據的直接和有效交換。另外，FHIRTerminalNode 還包括一個監視智能合約活動的 React 介面，並在特定事件的回應下在病患和衛生機構的端觸發 off-chain Docker 容器。在此系統中，衛生機構或研究者可以發起一個proposal，病患可以選擇participate。隨後進行性能實驗以評估系統的效率。FHIRTerminalNode 在數據交換的簡單性上，為醫療領域的健康數據共享提供了新的視角。

The advent of blockchain technology has significantly influenced medical data sharing, particularly with the sharing of Electronic Health Records (EHRs) controlled by health authorities. This study proposes a novel method for the private sharing of Personal Health Records (PHRs) between patients and health authorities, aiming to preserve patients' data ownership. A new system, FHIRTerminalNode, is introduced to facilitate this aim. FHIRTerminalNode leverages the Ethereum blockchain's smart contract functionality to provide a platform for sharing location and encryption information, thus facilitating the efficient exchange of medical health data. Additionally, FHIRTerminalNode incorporates a React interface that monitors smart contract activity and triggers off-chain Docker containers at both the patient's and health authority's ends in response to specific events. Within this system, a health authority or researcher can initiate a proposal to which patients can opt in. The system's efficiency is later evaluated through performance experiments. With its straightforward approach to data exchange, FHIRTerminalNode offers a fresh perspective on health data sharing within the medical domain.
