摘　　要：为了解决基于位置的服务(LBS)和增强现实(AR)技术快速发展带来的用户位置隐私泄露的隐患,分析了现有的位置隐私保护方法的优缺点,提出基于位置安全性的位置隐私保护方法。将区域安全度和伪装区域引入该方法中,将提示某区域是否需要保护这一度量标准定义为区域安全度,非安全区域(即需要给予保护的区域)的区域安全度设置为1,安全区域(即不需要保护的区域)设置为0,通过扩大区域安全度和识别等级来计算位置安全度。实验结果表明,该方法与未引入位置安全性的方法相比降低了平均定位误差,提高了平均安全性,从而有效地保护了用户的位置隐私,提高了LBS的服务质量。Rapid development of Location Based Service(LBS)and Augmented Reality(AR)technology lead to the hidden danger of user location privacy leakage.After analyzing the advantages and disadvantages of existing location privacy protection methods,a location privacy protection method was proposed based on location security.The zone security degree and the camouflage region were introduced into the method,and the zone security was defined as a metric that indicates whether a zone needs protection.The zone security degree of insecure zones(zones need to be protected)was set to 1 while that of secure zones(zones not need to be protected)was set to 0.And the location security degree was calculated by expanding zone security degree and recognition levels.Experimental results show that,compared with the method without introducing location security,this method can reduce average location error and enhance average security,therefore effectively protecting the user location privacy and increasing the service quality of LBS.
