摘要:	本研究為促進學生及教師背景資料之有效交流，提出一個保護資料關係人隱私資料的儲存架構。將資料以敏感與非敏感作為區分，供查詢者查詢非敏感資料。並透過公開透明的規則以及信任機制，以區塊鏈紀錄資料關係人對自己敏感資料分享之意願，落實使用者對自己資料的控制權，藉此增加資料隱私的信任度，並且有效地運用資料。知名公司 Netflix 曾舉辦了一場根據公開數據推測用戶電影評分的比賽 (Netflix Prize)，公開數據抹去了可識別用戶的訊息，但一年後，來自克薩斯大學奧斯汀分校的兩名研究員將公開數據與 IMDb(網路電影資料庫)網站公開紀錄進行關聯，識別出了匿名用戶的身份。;In order to promote the effective exchange of background information between students and teachers, this research proposes a storage architecture that protects users’ private data. Users’ data are classified according to sensitivity, for queriers are allowed to query only nonsensitive data. For the purpose of implementing the users’ control over their own data, blockchain is used to record the users’ willingness to share their sensitive data. In addition, it can also increase the trust in data privacy in decentralized environment with public rules and trust mechanism. The well-known company Netflix once held a competition(Netflix Prize) to estimate user movie ratings based on public data. The information that can identify users had been erased already. However, a year later, two researchers from the University of Texas at Austin correlated those data with public data records on the IMDB(Internet Movie Database) website to identify anonymous users.
