Abstract

The invention discloses a face identification based authentication method and device. One detailed description of the method includes responding to determining that a to-be-authenticated face image isin a preset face identification area, and determining attitude information corresponding to the to-be-authenticated face image; generating an attitude reference line based on the attitude information; judging whether the attitude reference line matches a preset attitude adjustment area, wherein the attitude adjustment area belongs to the face identification area; and performing face identification on the to-be-authenticated face image if yes so that whether a user corresponding to the to-be-authenticated face image is an authentication user can be determined. Thus, face identification accuracy of the to-be-authenticated face images can be enhanced.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of network security technology, and in particular to an authentication method and device based on face recognition. Background technique [0002] Face authentication is an important method for identifying user identities in financial scenarios. This authentication technology is to determine whether the operator of the account is the user himself or not by comparing the face image collected on the client with the photos in the face database. [0003] However, the accuracy of face authentication depends on whether the collected face image is a "frontal" image of the face. That is to say, whether the current posture of the face is facing the collection device (for example, camera) that collects the face image. If the posture of the user's face is not facing the capture device, for example, turning left or right relative to the capture device, raising the head,...
