Onstar系统广泛应用在导航和卫星定位等系统中，基于Onstar系统的空间区域模糊搜索算法是解决网络隐私保护和源位置挖掘等关键问题的基础。传统方法采用决策树构建算法DiffP-C4.5的网络隐私保护机制，性能不好。提出一种基于OnStar源位置网络隐私保护的空间区域模糊搜索算法，研究OnStar系统路由协议模型，设计路由转发及隐私保护容错机制，对每层的最小竞争窗口值的调节系数设计为定值，得到每轮消耗的隐私保护预取值。计算OnStar源位置加密信息系统传输的通信量，进行OnStar源位置网络隐私保护的空间区域模糊搜索算法改进。实验分析得到，该算法能报确保Onstar原位置网络用户的空间区域隐私性，对空间区域的模糊搜索精度较高。

The Onstar system is widely used in navigation and positioning system, the regional space fuzzy search algorithm is the basis to solve the key problems of network privacy protection and source location. Traditional methods use decision tree construction algorithm of DiffP-C4.5, the performance is not good. The regional spatial OnStar source location fuzzy search algorithm is proposed for network privacy protection, OnStar routing protocol is researched. The routing forwarding and privacy protection of fault-tolerant mechanism is designed, the minimum contention window value adjustment factor is set to the value in each round of the pre consumption privacy protection value. Traffic of OnStar encryption transmission source location information system is calculated, regional spatial OnStar source location of network privacy protection im?proved fuzzy search algorithm. Experimental analysis shows that this algorithm can ensure the privacy of the Onstar newspa?per space area of original position of users in the network, fuzzy regions of space search precision is high.
