Recently, location based services (LBS) have become more important in today technology advancements. Privacy issue in LBS is one of the most important concerns. In this paper, we have proposed an anonymity preserving framework which can provide a user with more privacy in both authenticating and querying processes. In our framework, an authentication protocol has been proposed, in order to strengthen a privacy, a technique called "Timed Fuzzy Logic" is used. In querying processes of location based services, the use of the Anonymizer, a trusted third party, to provide users anonymous querying and requesting processes is presented. Moreover, when concerning on privacy in user's context, k-anonymity cloaking has been employed for the purpose of preventing user's current location from tracking.
