大多数智能手机应用程序的用户仍然不知道他们的哪些数据正在被收集，由谁收集，以及这些数据是如何被使用的。在这项混合方法调查中，我们研究了揭示智能手机应用程序的关键数据收集实践是否可以帮助人们做出更明智的隐私相关决策的问题。为了调查这个问题，我们设计并原型化了一种新的隐私指示器，称为数据控制器指示器（dci），它可以暴露以前隐藏的信息流。我们对数据中心的实验室研究表明，这些指标确实有助于人们做出更自信、更一致的选择，这些选择是由更多样化的因素决定的，包括访问用户数据的第三方公司的数量和性质。此外，个性化的dci（与个人已经使用的其他应用程序相结合）使他们能够有效地推断出对其整体信息暴露的不同影响。
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.
