Trade secret is the "secret weapon" for enterprises to be invincible in the fierce market competition. Information is internationally recognized as the fourth major factor of production after capital, technology and talents. Rio Tinto's commercial leaks shocked the whole steel industry, and at the same time overturned the confidentiality principle of "I don't commit crimes, people don't commit crimes against me" that has been pursued by state-owned enterprises. During the development of enterprises in China, emphasis is placed on improving their own competitive strength, while few measures are taken to protect business secrets that can enhance their competitive strength, thus leaving many opportunities for secret thieves. More than 90% of foreign companies have special intelligence departments to protect their own business secrets, and at the same time obtain the business secrets of competitors through various means. The internal secrecy protection of enterprises is weak, the international economic competition is fierce, and the secrecy environment of loose inside and tight outside poses a severe challenge to the protection of business secrets of enterprises. Information globalization has narrowed the distance between enterprises, and the competition for business information across national boundaries has become increasingly fierce. Facing the potential threat of domestic and foreign competitors stealing trade secrets, enterprises must strengthen the protection of trade secrets.
