车联网在通过位置服务中解决道路安全问题、为驾乘者提供便捷服务的同时，也带来了相应的隐私保护问题。文章总结了隐私保护内容，重点分析了车联网的假名隐私保护技术，假名方案分为基于特殊地形、基于安静时段、加密Mix-zone。不同的假名方案在不同的道路特征下会有特定的应用场景。继而针对隐私保护水平的高低，着重分析了特殊地形的Mix-zone的性能。

Location-based services in IOV solved the problem of road safety, and provided the convenient services to drivers and passengers. But it also brought new problems of privacy protection. The content of privacy protection was analyzed, and put emphasis on two kinds of privacy protection technology based on pseudonyms and signature respectively.Pseudonym-based schemes were classiifed as special-area based, silence-period, cryptographic Mix-zones. Different pseudonyms schemes under different road characteristics will have speciifc application scenario. Then according to the level of privacy protection, emphatically analyzed the performance of the special terrain of Mix - zone.
