An audio/video stream generated by a target object to be authenticated is obtained. The target object is associated with a user. A determination is made whether a lip reading component and voice component in the audio/video stream are consistent. In response to determining that the lip reading component and voice component are consistent, voice recognition is performed on an audio stream in the audio/video stream to obtain voice content. The voice content is used as an object identifier of the target object. A model physiological feature corresponding to the object identifier is obtained from object registration information. Physiological recognition is performed on the audio/video stream to obtain a physiological feature of the target object. The physiological feature of the target object is compared with the model physiological feature to obtain a comparison result. If the comparison result satisfies an authentication condition, the target object is authenticated.
