| 摘 要： | 在移动互联网中，位置隐私保护一直是有待解决的重要问题。针对定位服务中的位置隐私问题，提出了一种位置隐私保护方法KAP。KAP适用于WLAN定位技术。首先，提出了一种区域热点拓扑模型，将WLAN热点的地理分布用带权无向图描述，该模型能够在不使用WLAN热点坐标的前提下，反映热点之间的位置关系。然后，基于拓扑模型并结合k-匿名思想，提出了3种位置隐私算法，保证了位置不被攻击者准确获得。最后，通过仿真实验，验证了方法的正确性。

| Abstract: | Preserving location privacy is an essential requirement in mobile internet. A location privacy protection approach named KAP was proposed which aimed at the privacy issue of location service under the mobile Internet. Through the analysis on locating technology, a weighted adjacent graph-based topology model was given in order to describe the positional relationship between hot spots. Meanwhile, with the help of the model, combining the concept of k-anonymity, three privacy algorithms was shown to make sure the location can not be obtained precisely by attacker. The simulation results verified the correctness and performance of the approach. |
