Abstract

The invention relates to a face-identification-based living body determination method and equipment. The method comprises: obtaining a face image of a sample, carrying out first living body detection and second living body detection on the face image, and calculating a first living body detection score and a second living body detection score of the sample; determining a score fusion strategy of fusion of the first living body detection score and the second living body detection score; obtaining a face image of a to-be-identified object, carrying out first living body detection and second living body detection on the face image, and calculating a first living body detection score and a second living body detection score of the to-be-identified object; according to the score fusion strategy, calculation a fusion score based on the first living body detection score and the second living body detection score of the to-be-identified object; and carrying out living body determination on the to-be-identified object based on the fusion score. Besides, a first face feature is extracted according to a mirror face reflection characteristic in the first living body detection; and a second face feature is extracted according to face key point changing in the second living body detection.

Description

technical field [0001] The invention relates to the fields of image processing and face recognition, in particular to a living body discrimination method and device based on face recognition. Background technique [0002] With the increasing demand for information security, the function of adding liveness detection to the face recognition system has received more and more attention. Common forms of facial attacks include photos, video playback, and 3D models. Playing photos and videos is the most common attack method, and people can easily obtain relevant information of legitimate users from mobile devices or surveillance cameras. [0003] With the development of modern technology, the synthesis of 3D faces and the acquisition of models are no longer difficult to achieve. For example, the service of ThatsMyFace.com can realize the reconstruction of 3D faces by uploading a frontal and a side photo. Customization of structure and 3D models. Compared with real faces, photo f...
