Abstract

The present invention provides a face in-vivo detection method and system based on a binocular camera. The method comprises the steps of (1) acquiring video images corresponding to an object under visible light and infrared light by using the binocular camera, (2) performing pre-processing on the video images to obtain denoised images, (3) performing face detection on the denoised imaged to obtainface regions, (4) extracting corresponding face key points in the face regions under the two kinds of light, (5) aligning and correcting faces of the face regions according to the face key points, and (6) extracting depth features of a face region corrected under the infrared light by using the deep neural network and detecting a real face and a forged face according to the depth features, wherein the deep neural network is FASDNet. The present invention also provides a face reading transaction method and system including the above in-vivo detection. A user is not required to actively cooperate, thereby a user experience is improved, and meanwhile, the application range of the in-vivo detection is expanded.

Description

technical field [0001] The invention belongs to the technical field of face recognition, and also relates to an electronic payment verification method, in particular to a binocular camera-based method and system for human face liveness detection and facial recognition transaction. Background technique [0002] Biometric technology is a technology that determines personal identity based on personal physical or behavioral attributes. At present, face recognition is widely used in the field of biometrics due to its directness, friendliness and convenience. In recent years, liveness detection technology and face recognition technology have been continuously applied to various business channels and business scenarios of banks. Common business scenarios such as facial recognition login, unlocking, and card application are gradually expanded and innovated for withdrawal and payment at self-service terminals. on payment. However, the face recognition system also has great security ...
