For　the　multiple　privacy　protection　demands　in　Locations　Based　Services　(LBS),　a　user-centric　trust　based　privacy　protection　model　was　proposed.　In　the　model,　user　can　set　their　privacy　preference　freely.　The　model　uses　a　method　base　that　integrates　kinds　of　privacy　protection　methods　to　protect　privacy.　According　to　the　trustworthy　of　network　environment,　the　trustworthy　of　location,　the　trustworthy　of　surrounding　users　and　the　trustworthy　of　service　providers,　a　method　which　meet　diverse　privacy　protection　requirements　was　chosen　from　the　method　base　on　the　basis　of　the　mapping　relationship　between　trust　and　privacy　protection　method.　Analysis　and　simulations　results　show　the　model　can　effectively　protect　privacy　also　with　high　quality　of　service.
