Privacy disclosure issue becomes more and more serious due to big data analysis.Privacy-preserving techniques should be conductive to the big data applications while preserving data privacy.Since big data has the characteristics of huge scale,numerous sources and dynamic update,most traditional privacy preserving technologies are not suitable any more.Therefore,the concept of privacy and life cycle protection model of big data era were introduced firstly.Technical state of big data privacy preservation was elaborated from the points of view of four stages in big data life cycle,i.e.data publishing,storage,analysis and use.The relative merits and scope of application of each technology were investigated as well.Finally,some important direction and tendency of privacy preservation technologies for big data were suggested.
