Living body detection method, device and equipment and storage medium

Abstract

The invention discloses a living body detection method, device and equipment and a storage medium, and belongs to the technical field of computers. According to the embodiment of the invention, the face areas in the color image and the infrared image of the target are respectively detected through the two cascaded branches in the detection model; whether the target is a living body or not is determined by integrating the detection results of the two images; on one hand, a face region in a color image is detected; according to the method, black-and-white printing and infrared printing images can be effectively defended, detection of a face area in the infrared image is combined, attacks of screen images and color printing images can be effectively defended, and therefore the comprehensive defense effect is achieved, the defense effect is good, practicability is good, and the accuracy of the detection result is good. And on the other hand, different requirements of the two images on theenvironment information are considered in the comprehensive process, and the weight of the two images during combination is determined according to the environment information of the target, so that the accuracy of the detection result obtained by weighting is better, and the defense effect is better.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a living body detection method, device, equipment and storage medium. Background technique [0002] With the development of computer technology, living body detection technology has been widely used in various fields. Liveness detection technology refers to the method of determining the real physiological characteristics of the object in some authentication scenarios. In some scenarios, it is necessary to verify whether the current operation is performed by a real person. If it is not operated by a real person, it will be regarded as an attack. business logic. [0003] Common attack methods include various printing photo attacks (such as color printing photos, black and white printing photos, infrared printing photos, etc.) and screen playback attacks (such as mobile phone screens, tablet screens, computer screens, etc.). At present, the living body detection me...
