LPBS - Location Privacy Based System

The use of geographical information about users is the main quality of Location Based Services (LBS). Services like finding routes between places or finding friends can offer benefits and facilities. However, the misuse of location information can raise some threats to the user´s privacy. We present the Location Privacy Based System (LPBS), a system that guarantees LBS execution with privacy relying on a multi-level approach. By using different techniques we can offer distinct levels of privacy. Therefore, the system presented in this paper is able to attend different requirements and preferences of users. Besides, LPBS follows the recommendations of existing privacy guidelines.
