Description

technical field

[0001] The invention belongs to the technical field of computers, and relates to a safe and confidential computer, in particular to a physically isolated computer with one computer and two networks. The invention can be used not only in the industrialized production of integrated desktop computers, but also in the industrialized production of all-in-one computers and notebooks. Background technique

[0002] With the rapid development of the Internet, computer network leaks are becoming more and more serious, and the problem of confidential data loss in confidential computers has become a very headache for party and government agencies, military, national defense, scientific research institutions and public service organizations that collect basic information of citizens. . According to relevant data, in the current secrecy work, leaks caused by computer networks and computer data loss have accounted for more than 70% of the total number of leaks, and are sho...
