摘要:

为了解决车联网中车辆用户使用基于位置的服务(LBS)时真实位置的泄露问题,提出一种基于公交车缓存的位置隐私保护方案。公交车先根据其线路信息向LBS提供商获取兴趣点(POI)池,然后在行驶时根据其当前位置从POI池中挑选部分POI数据形成POI列表并广播给周围私家车。私家车在接收到广播信息后,验证公交车身份,然后将POI列表存储到车辆的本地缓存中。当私家车需要查询POI信息时,首先在本地缓存中进行检索,若缓存未命中再以 k-匿名的方式向 LBS 提供商发送查询请求。仿真实验结果表明,所提方案通过减少私家车与LBSP的通信次数,能够降低私家车真实位置泄露的可能性,从而有效提高私家车的位置隐私保护水平。

Abstract:

To solve the problem of real location leakage when vehicles use location-based service (LBS) on the Internet of vehicles, a location privacy protection scheme based on bus cache was proposed.Firstly, a point of interest (POI) pool was obtained from the LBS provider based on its route information.Then the data in the POI pool was selected form a POI list while driving.Finally, the POI list was broadcast to surrounding private vehicles.After the private vehicle received the broadcast data, it verified the identity of the bus and then stored the POI list in the vehicle’s local cache.When a private vehicle needed to query POI information, it would first retrieve it in the local cache, and if the cache was missed, it would send a query request to the LBS provider using the k-anonymity method.The simulation experiment results show that the proposed scheme can reduce the possibility of leakage of the real location of the private vehicle by reducing the number of communications between the private vehicle and the LBSP, thereby effectively improving the privacy protection level of the private vehicle.

Key words: Internet of vehicles, location-based service, privacy protection, k-anonymity
