The data is the company’s core assets, data security is the core of the system security. With cloud computing, big data technologies are widely used to increase the difficulty of data protection, data security risks automatic recognition model for data security will play a very important role. Firstly, the use of Cartesian set to establish a formal risk character-ization, lay the foundation for the automatic identification of risk;Secondly, according to the data flow through the filter of risk, determine the data security risks set different environments;Finally, in order to improve rules adaptation, the use of rough set learning the rules of security incidents, which greatly improves the accuracy of risk identification, the model for the data security protection provides a new and effective means. The theory and the algorithm of the artificial neural network are applied in the research of the technique and the composition, the gross mass fraction of element, the thickness of surface alloying layer as well as the absorption rate is built. The calculation results are in good agreement with the experimental results.
