With the continuous development of Internet technology, more and more fields are beginning to use Internet technology to improve their business construction. Moreover, in terms of e-government construction, introducing the Internet technology into e-government work at all levels is also an important content, and the Party Central Committee has proposed a series of major decisions such as network power and “Internet +” to accelerate the process of e-government informatization. Meanwhile, big data virtualization technology and access control technology are used to break through e-government data sharing barriers to realize virtual integration and trusted sharing across e-government data and support multi-departmental, crosslevel, and cross-network data security interactive processing for e-government business collaboration. Besides, the multi-source circulation and on-demand access of cross-departmental e-government data are realized to break data barriers, form data transmission links, and create a model for exchanging and sharing e-government data. Through the exchange and sharing of e-government data, the barrier-free flow of information can be achieved and the efficiency of e-government business handling can be improved as well.
