Abstract:	在當代醫療領域，人工智慧於影像分析的應用推動了醫療影像資料共享平台的發展。這些平台整合多機構醫療影像資料，確保僅授權使用者讀寫敏感資訊。然而，傳統中心化資料庫存儲授權資料面臨資料竊取、篡改及單點故障風險，挑戰隱私保護與授權透明度。如果授權資料保存不當或是授權過程出現錯誤，將可能導致未經授權者存取敏感資料，進而引發嚴重的隱私洩露和法律糾紛，同時削弱公眾對資料共享平台的信任，影響平台的長期運作和發展。本研究開發出一套基於以太坊區塊鏈技術的授權驗證系統，該系統通過RESTfulAPI 與醫療平台進行整合，並搭配rabbitMQ等分散式系統處理大量整合資料。應用區塊鏈的去中心化和不可篡改性質，本系統能夠安全地將授權資料儲存在智能合約中，並透過智能合約自動化方法審核存取權限，將驗證和資料存取機制過程封裝在智能合約中，大幅降低了資料洩漏的風險，並保障了授權驗證的準確性。本系統還應用Vault-BX 技術，實現對私鑰調用權和管理權的分離，使智能合約上資料的讀寫過程更加嚴謹。本研究通過所述方法和系統架構，提升了資料共享的可追蹤性和安全性，進一步促進了這些平台的順利運作，從而構建了一個良好的資料共享生態系。 In modern healthcare, AI-driven image analysis has fostered the develop ment of medical image data sharing platforms that integrate data from mul tiple sources. These platforms ensure only authorized users can access sen sitive information, but traditional centralized databases pose risks like data theft and tampering, potentially leading to privacy breaches and undermining public trust. ThisstudyintroducesanauthorizationverificationsystembasedonEthereum blockchain technology, interfacing with medical platforms through RESTful API and managing data with systems like RabbitMQ. The blockchain’s de centralized nature ensures secure storage of authorization data in smart con tracts, significantly reducing data breach risks. The use of VaultBX technol ogy enhances private key management, ensuring robust data handling. This systemenhancesdatasecurity andtraceability, thereby facilitating the smooth operation of platforms and fostering a robust data sharing ecosystem
