> 中文摘要: 对现有移动社交网络应用中的位置隐私问题提出了新的理解,总结了3 类主要可能造成隐私泄露风险的原因和3 类与之对应的必要保护手段,并且提出了一种结合策略与算法的位置隐私保护机制.在同时构建的基于位置感知的移动协作应用原型系统LaMOC 上,该隐私保护设计能够有效从两方面全面保护用户的位置隐私.一是支持用户通过灵活的策略方式,完全控制自身的位置信息共享方式;二是通过隐私保护算法使恶意攻击者无法得到用户的敏感位置信息.该隐私保护设计在一定程度上有效保护了移动社交网络应用中的用户位置隐私.
Abstract:The emergence of location-aware mobile social networking applications (SNAs) has gained considerable prominence in ubiquitous computing. However, the weak designs of privacy protection result in more potential risks that users have to face. This paper presents a deep insight into the designs of privacy protection, especially from the perspective of location privacy. Three main potential risks and some necessary privacy-related functionality in current applications are analyzed and summarized. And with respect to the risks and weak protection methods, we propose the designs of privacy protection in LaMOC which is a location-aware mobile cooperation system developed by us. The designs include both the policy-based mechanisms and computational approaches to protect users’ location privacy. Policy-based mechanisms enable users to fully control their locations disclosure while computational approaches can protect users’ real locations from malicious attackers. The designs provide a reasonable level of privacy protection in location-aware mobile SNAs to some extent.
