The invention relates to a face verification method and device and a computer storage medium. The face verification method comprises the steps of performing face detection and alignment on a to-be-verified image; dividing a plurality of predetermined face image blocks on the obtained face image; processing the face image by using a pre-trained predetermined plurality of face recognition neural networks to obtain predetermined plurality of features of a plurality of predetermined face image blocks of the face image; analyzing the face image by using a pre-trained face exposure area segmentationneural network, and obtaining a shielding area of a plurality of predetermined face image blocks of the face image based on an analysis result and the plurality of predetermined face image blocks ofthe face image; determining respective weights of a plurality of predetermined face image blocks of the face image based on the shielding area; and performing face verification according to the predetermined plurality of features and the corresponding weights. According to the face verification method and device provided by the invention, the deterioration of face verification performance caused by shielding can be reduced.
