Abstract: In the era of information technology, the application of face recognition technology has brought great convenience to people's production and life, but at the same time, there are also problems of recognition dislocation, discrimination, and violation of informed consent rules, which may lead to the invasion of privacy. In response to the above problems, the United States adopts a decentralized legislative regulation mode for the application of face recognition technology, and establishes differentiated regulatory paths according to the different subjects of face recognition technology application, while the European Union adopts a unified and strictly restricted legislative mode. There are loopholes in China's legal regulation of the application of face recognition technology. We should encourage the development of emerging technology and improve the governance mechanism of multi-party participation based on the existing regulatory system. Specifically, it includes:establishing the principle of information processing accuracy to ensure the safety of personal information in the application of face recognition technology, improving the "informed consent" rules and relief measures for privacy infringement, and comprehensively protecting facial feature information according to different department laws.

Key words: face recognition, facial features information, legal regulation, privacy, informed consent
