Review on location privacy protection research
2015, 2015 (5):
In recent years, with the development of wireless communication technology and mobile positioning technology, applications relating to locationbased 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 nonnegligible 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.
