摘要：Location-Based Service (LBS) becomes increasingly popular with the dramatic growth of smartphonesand social network services (SNS), and its context-rich functionalities attract considerable users. Many LBS providersuse users’ location information to offer them convenience and useful functions. However, the LBS could greatly breachpersonal privacy because location itself contains much information. Hence, preserving location privacy while achievingutility from it is still an challenging question now. This paper tackles this non-trivial challenge by designing a suite ofnovel fine-grained Privacy-preserving Location Query Protocol (PLQP). Our protocol allows different levels oflocation query on encrypted location information for different users, and it is efficient enough to be applied in mobileplatforms.
