the preset similarity calculation method may be the same as that in step S15, or may be another similarity calculation method different from that in step S15, and is not limited herein.
If the server side confirms that the matching between the effective face image and the face image of the video user is successful, the identity verification result is that the identity of the contract signing party is legal, and if the server side confirms that the matching between the effective face image and the face image of the video user is failed, the identity verification result is that the identity of the contract signing party is illegal.
