DaaS is a kind of cloud service which can provide the database services for others based on cloud infrastructure.It can effectively solve the difficulty of storage and management for massive data of individuals and enterprises.However,privacy leaks greatly hinder the development of DaaS.How to enhance the privacy protection of the existing DaaS becomes an urgent problem needed to be solved.Adopting the literature analysis method,this paper firstly summarized service architecture of DaaS and its privacy leaks mode.Then comprehensively analyzed the present researches on data confidentiality,query privacy preserving and query result validation,privacy preserving during data integrity validation of DaaS.From the analysis,it can be inferred that existing privacy preserving methods exist varying degrees of impairment in the aspects of efficiency of data update and query of DaaS and its practical applications.How to design more efficient algorithms for data confidential and the data queries with privacy preserving and query results validation are still the future research focus.Finally,it gave the he future research directions of in the privacy preserving in DaaS.
