移动定位社交服务下的位置隐私保护方法
Location privacy protection in location-based social networking services
摘要
Abstract
In order to protect the user's location privacy without compromising the quality of the mobile social networking service, this paper proposes an enhanced K-anonymous location privacy protection model based on a K-anonymous model. In order to achieve the goal of the user location privacy protection,the model looks for other "K-1"location information which is the closest to the target location information from the perspective of time and space,reducing information granularity by generalization. All the location information can not be distinguished from each other. Location history anonymity algorithm is put forward for the anonymity protection of location history. Experiments show that this method has higher efficiency on constructing an anonymous subset.关键词
