Mobile Systems Privacy: 'MobiPriv' A Robust System for Snapshot or Continuous Querying Location Based Mobile Systems

摘要: Many mobile phones have a GPS sensor that can report accurate location. Thus, if these location data are not protected adequately, they may cause privacy breeches. Moreover, several reports available where persons been stalked through GPS. The contributions of this paper in two folds. First, we examine issues snapshot queries, and present our work results area. proposed method guarantee all queries protected, while previously algorithms only achieve low success rate some situations. Next, discuss continuous illustrate current solutions cannot be applied to queries. Then, for robust models We will introduce novel suite called MobiPriv addressed the shortcomings previous query systems. evaluated efficiency effectiveness scheme against anonymization approaches. For experiments, utilized real world traffic volume data, road network users generated realistically by object generator.
