本研究以臺灣教育部全國數位證書推動計畫的實務建置成果為基礎，提出了一種符合政府與高等教育機構需求且遵從 GDPR 法規的區塊鏈數位證書永久儲存框架。本研究首先提出一種採用客戶端加密的數位證書文件儲存方法，該方法能解決個人資料保護問題。再來利用糾刪碼技術將證書分片，並將片段儲存在不同的儲存節點上，以避免單點故障的問題與高等教育機構退場的情況。最後本研究透過區塊鏈的智能合約定義了 Certificate 的通用型數據結構，以提升數位證書的可用性和可及性。總體而言本研究提供了一種優化、創新且遵循法規的數位證書儲存與分享框架，並為未來數位學位證書的優化與改進提供了實驗數據與具體方向。

This study, based on the practical achievements of Taiwan's Ministry of Education's National Digital Diploma Promotion Plan, proposes a blockchain-based digital Diploma permanent storage framework that meets the needs of the government and higher education institutions while adhering to GDPR regulations. The study first proposes a client-encrypted digital Diploma document storage method, which can resolve personal data protection issues. Then, by using erasure coding technology to fragment the Diploma and store the pieces on different storage nodes, the issues of single-point failures and the withdrawal of higher education institutions can be avoided. Finally, this study defines a universal data structure for Certificates through blockchain smart contracts to enhance the usability and accessibility of digital certificates. Overall, this study provides an optimized, innovative, and regulatory-compliant framework for storing and sharing digital certificates and offers experimental data and concrete directions for the future optimization and improvement of digital degree certificates.
