Facebook和Foursquare等流行的在线社交网络平台上的位置信息共享为这些平台的用户(例如基于位置的免费服务)以及平台提供商(例如基于位置的企业)带来了互惠互利。然而，阻碍这些互惠互利的一个明显问题是与用户位置数据相关的隐私问题，这也限制了他们的积极参与。在这篇文章中，我们分析了现有的位置隐私保护机制在最小化这种相互利益损失方面的作用。我们的分析表明，现有的大多数机制要么忽视了社交平台相关的用户隐私关切，要么忽视了平台提供商与位置数据质量相关的需求。此外，我们还指出了与现有隐私机制相关的具体研究差距和实施问题。
Location information sharing on popular online social networking platforms like Facebook and Foursquare brings mutual benefits for the users of these platforms (e.g., free locationbased services) as well as the platform providers (e.g., locationbased businesses). An obvious problem however that impedes these mutual benefits are privacy concerns related to location data of users, which also curb their active participation. In this paper, we analyze the role of existing location privacypreserving mechanisms in minimizing this mutual loss of benefits. Our analysis reveals that most existing mechanisms either ignore social platform related user-privacy concerns or they disregard location data-quality related demands of the platform providers. Moreover, we also point out concrete research gaps and implementation issues related to existing privacy mechanisms.
