The face unlocking method, device and system as well as the storage medium disclosed by the invention have the advantages that an unlocking process is simple, the unlocking speed is high, action cooperation of the user is not needed, interaction experience is good, and also the security is high, and attack of non-privileged persons can be effectively prevented.

Description

technical field [0001] The present invention relates to the field of face recognition, and more particularly to a face unlocking method, device, system and storage medium.
