Abstract:

With the advances in wireless communication technology and smart mobile devices, location-based services (LBS) providing personalized services based on users' location information, have been widely applied in many areas. However, direct publishing locations may present serious threats to individuals' privacy. Firstly, the general concepts and essential features of context-aware location privacy-preserving techniques were briefly introduced. Secondly, a survey of existing work, including the degrees of privacy preservation, QoS (quality-of-service), system architecture and adaptabil-ity of context-awareness, mainly analyzes and summarizes the state-of-art location privacy preserving strategies and models. Finally, after reviewing the main progresses of context-aware privacy preserving techniques in recent years, the present problems and development trend of the area were discussed.

Key words: located-based service, privacy preservation, location privacy, context-awareness
