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.

Key words: location privacy, mobile internet, k-anonymity, location service
