Preserving privacy of an individual while accessing location based information from Location Based Services (LBSs) is one of the most challenging tasks as the user unknowingly reveals the personal location in this process, where the location information can be tracked continuously and can be exploited. Sometimes it is required that the user does not provide false information about his location to the server querying as in some military applications. In such cases location aggregation technique is used by implementing two location anonymization algorithms namely resource aware and quality aware location anonymization algorithms which rely upon well known k-anonymity privacy concept in which a person is unidentifiable among k persons.
