Abstract

The invention discloses a face verification method and device, wherein the method comprises: obtaining a textured face image to be verified and an initial face image; using a preset descreening model to descreen the textured face image Operate to obtain the de-screened face image; perform feature extraction on the de-screened face image through the preset de-screened face verification model, obtain the de-screened face feature, and pass the preset de-screened face verification model Feature extraction is performed on the initial face image to obtain initial face features; based on the de-screened face feature and the initial face feature, the de-screened face image and the initial face image are verified. According to the pre-trained de-screened model and de-screened face verification model, the present invention automatically processes and analyzes the de-screened face image that needs to be verified and the initial face image, without the need for manual operation by professionals, and automatically distinguishes the out-of-network Whether the tattooed face image and the initial face image are of the same person can improve the efficiency and accuracy of face verification.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a face verification method and device. Background technique [0002] With the rapid development of Internet technology, it is particularly important to ensure the security of user accounts through face verification. Face verification is a branch of the field of face recognition. Using the face verification algorithm, two face photos can be automatically verified to determine whether they are the same person. This method can be used for user face identity verification in multiple scenarios such as Internet finance. [0003] At present, in order to protect the privacy and security of citizens, textured watermarks are added when photos are uploaded, so as to obtain textured photos, such as ID card face photos, social security card face photos, passport face photos and other ID photos. When performing face verification on a textured photo, professionals need to us...
