Research progress on big data security technology

As a new and energetic realm of economic development, an innovative engine of social development, and a strategic tool for shaping national competitiveness, big data significantly effects peoples lives. However, improved social awareness of data value and vigorous development of big data platforms mean that big data security is increasingly hindering the promotion of big data applications. Meanwhile, as big data technology and framework continue to evolve, researchers still have different understandings of the core ideas and key features of big data security, and a unified big data security framework has yet to be established. Currently, determining the state-of-the-art of big data security technology is urgently needed to provide reference for research aimed at solving key big data security issues. Following a typical big data system technology framework, this review builds a novel big data security technology framework around big data security requirements. With this framework, state-of-the-art key big data security technologies are systematically summarized from three aspects: big data secure sharing and trusted services, big data platform security, and big data security supervision, which includes the main security mechanisms involved in big data business processes and system technology frameworks. Finally, big data security technologys core issues and development trends are summarized.
