Abstract
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.
