Better the Devil You Know: Exposing the Data Sharing Practices of Smartphone Apps

論文アブストラクト:Most users of smartphone apps remain unaware of what data about them is being collected, by whom, and how these data are being used. In this mixed methods investigation, we examine the question of whether revealing key data collection practices of smartphone apps may help people make more informed privacy-related decisions. To investigate this question, we designed and prototyped a new class of privacy indicators, called Data Controller Indicators (DCIs), that expose previously hidden information flows out of the apps. Our lab study of DCIs suggests that such indicators do support people in making more confident and consistent choices, informed by a more diverse range of factors, including the number and nature of third-party companies that access users' data. Furthermore, personalised DCIs, which are contextualised against the other apps an individual already uses, enable them to reason effectively about the differential impacts on their overall information exposure.

日本語のまとめ:

ユーザが入力したデータがどの行き先で何の目的に使用されているかを可視化し、ユーザがそのアプリに対する意識の持ち方が変わるかどうかを検討した。アプリを提供する企業はユーザに対しデータの使用目的を公開し、信頼を増やすことが重要だということが示された。
