Abstract

Location cloaking methods enable the protection of private location data. Different temporal and spatial approaches to cloak a specific user location (e.g., k-anonymity) have been suggested. Besides the research focusing on functionality, little work has been done on how cloaking methods should be presented to the user. In practice common location referencing services force the user to either accept or deny exact positioning. Therefore, users are not enabled to regulate private location information on a granular level. To improve the usage of location cloaking methods and foster location privacy protection, we conducted a user study (N = 24) comparing different visualized cloaking methods. The results of our lab study revealed a preference for visualizations using already known and well understood real world entities. Thus, the usage of simple and real world concepts can contribute to the application of cloaking methods and subsequently to location privacy protection.

哪件斗篷最适合你?:比较移动用户的位置隐藏方法

位置隐藏方法可以保护私人位置数据。已经提出了不同的时间和空间方法来掩盖特定的用户位置(例如，k-匿名)。除了关注功能的研究之外，关于隐形方法应该如何呈现给用户的研究很少。在实践中，常见的位置引用服务迫使用户要么接受要么拒绝精确定位。因此，用户无法在粒度级别上管理私人位置信息。为了提高位置隐身方法的使用，促进位置隐私保护，我们进行了一项用户研究(N = 24)，比较了不同的可视化隐身方法。我们的实验室研究结果显示，人们更倾向于使用已知和理解的现实世界实体进行可视化。因此，使用简单和真实世界的概念可以有助于隐形方法的应用，从而有助于位置隐私保护。
