Identity verification method, identity verification device, terminal and storage medium

The embodiment of the invention discloses an identity verification method, an identity verification device, a terminal and a storage medium, wherein the identity verification method comprises the steps of: when the identity verification request of a user is detected, acquiring network environment information of an access control machine and the facial image of the user; obtaining an identity verification mode and a reference data obtaining mode corresponding to the network environment information; according to the reference data obtaining mode, reading data from the database of the access control machine as a reference data set; according to the identity verification mode, matching the facial image with data in the reference data; and, if the matching result satisfies a pre-set condition,determining that identity verification of the user is passed, and controlling the access control machine to allow the user to pass. By means of the scheme, the face verification efficiency and the effectiveness can be increas
