在野外识别隐私偏好信号
Conflicting Privacy Preference Signals in the Wild
摘要：
隐私偏好信号允许用户表达对其个人数据处理方式的偏好。当这些信号引用可执行的法律依据时，它们在确定隐私结果时变得重要，例如最近的全球隐私控制和透明度与同意框架等信号。然而，多个隐私偏好信号的共存产生了模糊性，因为用户可以发送多于一个信号。本文收集了有关上述两个信号和历史上的“请勿跟踪”信号产生的模糊性的证据。我们提供了第一个经验证据表明，模糊的信号是由网络用户在野外发送的。我们还表明，浏览器中存储的偏好是网络对话框中表达的隐私偏好的可靠预测因素。最后，我们提供了第一个证据，表明流行的cookie对话框被大多数采用“请勿跟踪”和“全球隐私控制”标准的用户所阻止。这些实证结果为即将到来的关于如何解释隐私偏好信号的法律辩论提供了信息。
英文摘要：
Privacy preference signals allow users to express preferences over how their personal data is processed. These signals become important in determining privacy outcomes when they reference an enforceable legal basis, as is the case with recent signals such as the Global Privacy Control and the Transparency & Consent Framework. However, the coexistence of multiple privacy preference signals creates ambiguity as users may transmit more than one signal. This paper collects evidence about ambiguity flowing from the aforementioned two signals and the historic Do Not Track signal. We provide the first empirical evidence that ambiguous signals are sent by web users in the wild. We also show that preferences stored in the browser are reliable predictors of privacy preferences expressed in web dialogs. Finally, we provide the first evidence that popular cookie dialogs are blocked by the majority of users who adopted the Do Not Track and Global Privacy Control standards. These empirical results inform forthcoming legal debates about how to interpret privacy preference signals.
