The invention relates to a living body recognition method and device, computer equipment and a storage medium. The method comprises the steps that a to-be-processed image is acquired, the to-be-processed image is converted into a first image through a conversion layer of an identification model, the to-be-processed image and the first image correspond to different attributes, and the attributes comprise a forged image and a non-forged image; feature extraction is performed on the to-be-processed image and the first image through an identification layer of the identification model to obtain a feature map of the to-be-processed image and a feature map of the first image; a residual image between the to-be-processed image and the first image is determined according to the feature map of the to-be-processed image and the feature map of the first image; and living body recognition is performed on the to-be-processed image based on the residual image to obtain a category of the to-be-processed image, the category is a living body or a non-living body. By adopting the method, whether the to-be-processed image is a living body can be accurately identified.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a living body identification method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, living body recognition technology has appeared. Liveness detection refers to the technology that the user takes corresponding actions according to the system instructions, such as blinking, shaking the head, saying a series of numbers, etc., to prevent the user from using photos to deceive the system to complete the verification in some important environments. After the user performs actions according to the system instructions, the system will perform operations such as face detection, facial features positioning, and motion detection to determine whether the user's liveness detection has passed. [0003] However, malicious users can fool the liveness detection system by combining videos of various actions, r...
