| 摘 要： | 移动用户在享受基于位置的服务（LBS）的同时受到位置隐私泄露的威胁，因而提供有效的位置隐私保护策略至关重要。传统的位置隐私保护方法主要采用空间匿名的方式，若攻击者获得了更多与匿名空间相关的背景知识，尤其是与位置相关的语义信息，就会严重降低匿名效果。为了防止由位置语义分析造成的敏感位置信息泄露，并根据移动用户活动范围大多限定为道路网络的特点，提出一种基于位置语义的路网位置隐私保护方法，充分考虑了用户的个性化隐私需求，并通过实验验证了方法的可行性及有效性。

| Abstract: | Mobile users suffer location privacy leakage threat as enjoy location-based services (LBS).Therefore,it was important to provide effective policy for location privacy protection.Conventional protection approaches were mainly based on spatial cloaking,which leads to the anonymous effectiveness suffer great reduction if the attacker obtains more background knowledge with respect to the cloaking region,especially semantic information of the location.To prevent sensitive location information leakage for the location semantics being analyzed,and consider the characteristic that most users move on road networks,a location-semantic-based location privacy protection method for road networks was pro-posed.The proposed method considers users' personalized privacy requirements well.The feasibility and effectiveness of the proposed method are verified through experiments for many scenarios. |
