互联车辆地理信息传播中的隐私问题
Towards Privacy in Geographic Message Dissemination for Connected Vehicles
摘要：
通过地理信息传播，联网车辆可以获得附近的交通信息，从而对道路安全、交通管理或路线选择产生积极影响。由于此类消息通常在小的地理区域中相关，因此出于效率原因，服务器仅将消息分发给受影响的车辆。一个主要的挑战是，当从车辆收集位置更新并在消息被分发到地理相关区域时确定相关车辆组时，保持服务器基础设施的可扩展性，同时根据法律规定尊重个人用户的隐私。在本文中，我们提出了一个框架，地理信息传播的隐私设计和隐私的默认原则，而不必接受效率的缺点相比，传统的基于服务器-客户端的方法。
英文摘要：
With geographic message dissemination, connected vehicles can be served with traffic information in their proximity, thereby positively impacting road safety, traffic management, or routing. Since such messages are typically relevant in a small geographic area, servers only distribute messages to affected vehicles for efficiency reasons. One main challenge is to maintain scalability of the server infrastructure when collecting location updates from vehicles and determining the relevant group of vehicles when messages are distributed to a geographic relevance area, while at the same time respecting the individual user's privacy in accordance with legal regulations. In this paper, we present a framework for geographic message dissemination following the privacy-by-design and privacy-by-default principles, without having to accept efficiency drawbacks compared to conventional server-client based approaches.
