连续空间查询的位置隐私保护综述
Survey on location privacy preservation of continuous spatial queries
摘要
Abstract
In the mobile Internet,mobile users send their personal location information to location based service(LBS)pro-viders and obtain point of interest(POI)data via spatial queries.In a continuous spatial query,a user submits multiple loca-tions along his trajectory.This query led to serious user privacy risks.Recently,the location privacy preservation technique of continuous spatial queries became a research hotspot in the wireless network security and privacy area.First,this paper intro-duced spatial queries and privacy threats in LBS.Next,it summed up privacy preservation models for continuous spatial que-ries,and compared the corresponding privacy preservation methods.Finally,it indicated the trends and future directions.关键词
