摘要
随着增强现实技术和基于位置服务(LBS)技术的发展,增强现实的应用也越来越广泛,LBS是增强现实的一个重要应用,用户位置隐私的泄漏是LBS用户的重要威胁,因此对用户位置隐私的管理就显得非常重要。论文首先分析用户位置隐私保护的重要性,接着介绍用户位置隐私泄露的类型,并分析和比较目前已有的用户位置隐私保护方法的优缺点,最后提出含有集中受信任的第三方模型的用户位置隐私保护方法,该方法优化了现有的用户位置隐私保护方法,可以有效地实现用户位置隐私的保护。
With the development of augmented reality technology and location based services ( LBS ) technology, the application of augmented reality is applied more and more widely. LBS is one of the most important applications in augmented reality. The leak of user location privacy (ULP) is a major threat to clients of LBS. So the management of ULP is very important. It analyzed the importance of ULP protection, introduced the types of ULP leak and analyzed the advantages and disadvantages of the existing ULP pro~,cting meth- ods. Finally put forward an improved ULP protection method with centralized trusted third party model, which would optimize the existing ULP protecting methods and effectively realize the ULP protecting.
