Abstract

The invention discloses a living body detection method, a living body detection device and a storage medium. The method comprises the following steps that: an image containing a preset spectrum is collected; a target object in the image is identified, and the feature region of the target object is determined; the light reflection information of the feature region is obtained; and whether the target object is a living body object is judged based on the light reflection information of the feature region. With the living body detection method, the living body detection device and the storage medium provided by the technical schemes of the invention adopted, detection time can be reduced, and detection efficiency can be improved.

Description

technical field [0001] The present invention relates to face recognition technology, in particular to a living body detection method, device and storage medium. Background technique [0002] Face recognition is a biometric technology for identity recognition based on facial feature information. Usually, image or video acquisition equipment is used to automatically detect and locate the position of the face in the image, and then perform face recognition on the detected face. [0003] With the widespread popularization of face recognition technology, a series of potential personal security and privacy issues are gradually exposed, such as using face photos, face dynamic video clips or fake 3D face molds to simulate real people to deceive face recognition systems. In order to prevent this potential deceptive attack, the currently commonly used method is to judge whether it is a living human face based on the living body movement information, such as requiring the user to make ...
