Therefore, location-based applications are gathering attentions of people. On the other hand, using location information obtained by the mobile device is likely to violate the privacy of the user. In order to solve this problem, we propose and implement a privacy preserving method which is applied to applications of user’s geographical distribution. Compared to previous researches, our approach improved the accuracy of location data while keeping the privacy level.
