Data releasing service is one of the important issues in cloud computing platform. Privacy preserving on database application and service system is one of upmost factor which results if organization choices related such services in cloud computing environment. Therefore, it has important academic value and application prospect to study privacy preserving in cloud computing environment. Architecture of database application system in cloud scenario was defined; the ineKicient of AC merged with cryptog- raphy was analyzed; access control problem in multi - domain database application systems was discussed; fmthermore individual＇s privacy preserving issue in dynamic situation was studied; the classical privacy preserving model for data releasing situation was presented; data utility measurement methods for released data set were compared. Finally active research topics of database service in cloud computing environment were presented.
