A face recognition method, comprising the steps of collecting a face video, an image sequence and audio of a user, steps of recognizing a face movement and an access object identification, and steps of outputting a movement instruction and accessing confidential information according to a confidential relationship, thereby driving instruction and privacy confidentiality of a host system by means of the face movement and implementing living authentication for account codes of the user. With the present invention, inadvertent movements such as blinking may be recognized; and intentional movements such as blinking, frowning, opening one's mouth and nodding may also be recognized. At the same time, a recognition method by semantic instruction is provided, and said movements are used to drive various functions of a host subsystem. In addition, a confidential relationship having a one-to-one correspondence is established between the access object and accessed information, so that the confidential information is confidential to the access object on the basis of the face recognition. An artificial intelligence network algorithm, fuzzy recognition algorithm and genetic algorithm are used to recognize face movements. The present invention is used for confidential social interaction, confidential privacy, virtual reality (VR), augmented reality (AR), mixed reality (MR), helmet operation, financial payment, a game and a mobile phone APP.
