Abstract: | 近年來開放資料逐漸成為各國電子化政府的一項目標,其主因包含諸多益處例如資訊透明化、全民參與、海量資料分析、鼓勵第三方加值應用服務、等。但要達成以上目標並非易事,而隱私的問題正是其中時常被提及但鮮被深度探討的困難之一。藉此契機,此論文旨在利用台灣電子發票為例,分析政府開放資料可能帶來的隱私爭議,並嘗試提出解決方法或建議。
根據電子發票的資料交換標準訊息格式,我們合成出模擬用的資料並根據此資料提出許多可能的應用,例如經濟分析或食品安全網路、等,然而對與資料所記載的對象而言,這些應用也有相對應的隱私風險。為了在保護隱私和的前提下開放電子發票資料,我們套用QID-SA架構以建立攻擊模型並嘗試使用相關的匿名化技術來尋找能同時滿足隱私和資料可用度的解決方案。 經過分析,由於電子發票資料相對複雜,判斷尋求最佳解是極為困難的,因此我們假設了一些可能的非最佳解,惟必須設法讓隱私或可用度其中一方妥協方才可行。其他技術例如存取控制或資訊當責或許能填補匿名化的缺點,但這些概念卻違背了開放資料的初衷。即便如此,我們仍認為政府應積極參與並盡可能開放稍敏感的資料,因為正是這些資料才有研究、分析、及應用的潛力。結論來說,如果政府、企業、和人民三方能充分溝通合作,或許將不再需要妥協就能實現開放政府資料的願景。 Open data has been on the e-government agenda of many nations for it promises information transparency and encourages involvement of citizens in democratic processes. It also shares virtues with big data and suggests even more benefits due to its accessibility. However among the various barriers of implementation, the issue of privacy is frequently mentioned but lacks elaboration in literature. This thesis will use the Taiwanese E-invoice as case to explore the implications and processes of addressing privacy in open government data (OGD). Using the Message Implementation Guideline of Taiwanese E-invoice, sample datasets are synthesized then analyzed for applications they empower and privacy risks incurred. A well-researched concept, anonymization, is selected to address privacy-preserving data publishing via the QID-SA framework. Possible privacy attacks are modeled on this framework, and the effectiveness of anonymizing methods is assessed. The goal is to find an optimal solution, if it exists, that achieves good utility and privacy. Through analysis, we find such solution remains elusive due to the complexity of e-invoice data, and although suboptimal ones are suggested, substantial compromises must be made. Access control and information accountability may overcome the shortcomings, but these concepts deviate from the original goal of openly accessible data. Nevertheless, we still conclude that government should actively dislcose such ``unsafe' dataset despite the complications, for it is this kind of data that houses vast potential. Through communication with stakeholders and supporting legislation, we believe one day those compromises may alleviate and the prospect of OGD can be realized. |
