Current dramatical increasing demands of big data have driven a remarkable growth of the implementations of data mining, smart data, and data analysis in multiple domains. Security issues in applying big data have become a great concern for big data practitioners. IEEE BigDataSecurity addresses this domain and aims to gather recent academic achievements in this field.

Moreover, cloud computing is the second concentration of IEEE BigDataSecurity. The emerging mechanism of cloud computing has provided a variety of novel approaches addressing the solutions of big data. The new methods deriving from cloud computing have covered distinct dimensions, such as energy consumptions, high performance, and heterogeneous resources, cloud models, heterogeneous architecture, tele-health, resource allocation, load balance, multimedia, and QoS, etc.
