The existing study is mainly focused on demonstrating the advantages of big data technology from technical perspective and there is little detailed discussion on risks of technology application. There are three main risks for the application of big data technology. Firstly, too much emphasis on data analysis tends to ignore people’s free will and the right to be forgotten, and inhibit the possibility of people’s growth. Secondly, forecasting with the thinking mode of “the past determines the future” is easy to lead to preventive punishment and personalized discrimination. Thirdly, due to the abuse of technology and the restriction of social conditions, the existing data collection mode is easy to violate people’s privacy and other rights. To address the risks of big data technology application, we shall specify the theoretical basis of this technology to demarcate the application range, build hierarchical intervention system, extend different treatments to such problems as national ideological security, physical and mental health of students, diversified lifestyle, and raise the ideological and political education level on the premise of protecting individual rights.
