Abstract: In recent years, with the development of wireless communication technology and mobile positioning technology, applications relating to locationbased services (LBS) are increasingly taken seriously and used widely. On the one hand, LBS brings people considerable convenience; on the other hand, it becomes a nonnegligible security threat that users’ privacy, mainly including location privacy, trajectory privacy and identity privacy, could be leaked out. Many solutions on the basis of different structures of privacy protection system have been proposed by researchers at home and abroad, which can be divided into pseudonym, faked locations and spatial and temporal cloaking, protecting users’ identity privacy, location privacy and trajectory privacy respectively. In this paper, we contrast the existing privacy protection technologies and analyze challenges LBS is facing. At the same time, we conclude the existing researches and give directions for future research.

Key words: locationbased services, privacy protection, pseudonym, faked locations, spatial and temporal cloaking
