%X As the proliferation of mobile devices such as smartphones and tablets, location-based services(LBS) are becoming increasingly popular. LBS, albeit useful and convenient, posed a serious threat to users' privacy as they are enticed to reveal their locations to LBS providers via their queries for. How to protect users' privacy against potentially compromised LBS providers is of vital importance to the well being of the LBS ecosystem. Some solutions have been proposed to deal with location privacy problems in location-based services, however, there is still a distance to be widely used. In order to resolve the contradictions which have been not solved, and deeply study with the related topics, this paper overviewed the related literatures from four aspects: the not k-anonymous location privacy technologies, the k-anonymous location privacy technologies, the k-anonymous location privacy in the P2P environment technologies, and the anonymous location privacy for continuously querying technologies. It introduced the related algorithms. Finally it concluded the problem remaining and development orientation of the location privacy protection technologies.
