Abstract: While various information changes the society, it also ignited a revolution in information protection on the law. Civil aviation industry is a rising industry with massive information. The importance of its personal information protection cannot be underestimated. The personal information of civil aviation passengers has the characteristics of authenticity, national security, cross-border nature, multiple links and commodity, which is more prominent than the general industry. Due to the involvement of third-party information processors, the case of civil aviation passenger information leakage has also become more complicated. At present, China has more principled provisions on the protection of personal information, and the legislation is relatively scattered and not perfect. Personal information legal protection of the civil aviation passengers is insufficient in term of particularity. Legal system over civil passengers' personal information protection should be established with "laws, administrative regulation, regulations, standards (guidelines)". We shall clarify civil aviation passengers' personal information protection obligations and responsibility, establish recommended industry standard and construct a stereoscopic supervision in information governance.
