According to People's Daily, on November 9, Zhang Jingzhong, a mathematician and academician of the Chinese Academy of Sciences, said at the 2019 Chongqing Yingcai Conference that artificial intelligence is still experiencing vigorous development. At the same time, it still faces some difficulties, such as lack of legal protection and insufficient data fusion. The explosive growth of data brings information security issues. In his view, to achieve greater development in the field of artificial intelligence, it is necessary to build a strict legal protection system, break the information "island" between government, enterprises, institutions, and through blockchain, encryption technology, artificial intelligence algorithms, etc. Solve information security issues and create new growth points.
