Big data privacy security has become a hot research topic in contemporary society. Based on the data relevance and life-cycle in the era of big data, this paper analyzes the causes of security problems in China’s data privacy. It puts forward suggestions from three aspects to provide references for subsequent research. Based on the current research progress, this paper first sorts out the definitions of data privacy and data privacy protection, then summarizes the causes of privacy security from the perspectives of technology and management and reveals the consequences of data privacy security issues. The demonstrated results trigger an insight into the solution strategy of data privacy problems and offer suggestions for solving problems from the perspective of management based on the data life-cycle model. Finally, starting from other stages of the data life-cycle and the application scenarios of big data, this paper looks forward to the future research direction. This study found that the present study needs to focus on the combination of system and technology, the improvement of laws and regulations, and the data life-cycle model in both technical and institutional management.
