摘要：Now-a-days Location-Based Service (LBS) has become increasingly popular with the dramaticevolution of smartphones and social network services (SNS). Its context-rich functionalities attract significant users.Many LBS providers use information regarding users’ location to offer them convenience and beneficial functions.However, the LBS could significantly breach personal privacy because location itself contains much information.Therefore, preserving users’ location information and at the same time achieving utility from applications is still achallenging task. This paper deals with non-trivial challenge by designing a collection of novel fine-grained PrivacypreservingLocation Query Protocol (PLQP). The protocols designed allow different levels of location query onencrypted location information for different users and it can be applied to mobile platforms due to its high efficiency.
