Research on the two-way defense model of large data dynamic security SAT

摘要

To guarantee the safety of big data calculation, the concept of security research and trusted cloud combined with large data security, a two-way defense system model of a large data calculation of SAT. The model of user data evidence through the dynamic safety factor; gradually determine the behavior of security permissions according to the reliability test implementation behavior. Provide the maximum-security defense for users. the experimental results show that the model can effectively improve the data big data security, reduce malicious hackers, to improve the efficiency of data analysis.
