基于位置的服务中用户隐私保护方法

Method for Privacy Protection in Location-based Services

为了解决在基于位置的服务中保护用户隐私的问题,在基于位置的服务中用户所在位置作为个人隐私信息需要加以保护的特点以及本领域现有的隐私保护方法的基础上,提出了一个面向隐私保护的三维访问控制模型以及基于此模型的隐私保护方法.通过实例说明如何运用此模型来支持和实现在基于位置的服务中对用户的隐私进行保护.与现有的其他针对在基于位置的服务中保护隐私的方法相比,提出的访问控制模型能更完善、更灵活地保护用户的隐私信息.

To solve the ever-increasing challenging problem of privacy protection in location-based services（LBS） ,after studying the characteristics of privacy protection in LBS and current methods for privacy protection,a three-dimensional access control matrix model and the corresponding method based on the model for privacy protection are proposed. Then the application of the proposed model and method for privacy protection in LBS are illustrated through an example. Compared to other existing methods for privacy protection,the proposed model and method has the advantage of offering a comprehensive and flexible solution for the protection of user privacy.
