Face liveness detection method and device

Abstract

The present invention discloses a face liveness detection method and device and belongs to the image processing field. The invention aims to solve the problem of low accuracy and poor safety of an existing liveness detection method. According to the embodiments of the present invention, the method comprises the following steps that: a first image is acquired; face recognition is performed on the first image, the information of a target person in the first image is determined from pre-stored person information; target check actions are randomly generated, wherein the target check actions comprise at least two basic check actions; action prompting information is outputted according to the target check actions, wherein the action prompting information is used for prompting a user to make the target check actions within a preset time length; a second video is obtained, the time length of the second video does not exceed the preset time length; the target action of the target person is determined according to the second video; whether the target action is consistent with the target check actions is judged; and if the target action is consistent with the target check actions, it is determined that the check of the target person is successful.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for detecting human face liveness. Background technique [0002] With the rapid advancement of image processing and pattern recognition technology and the convenience of face recognition, face recognition systems based on video image processing have been widely used, such as face recognition in attendance, access control, security monitoring and other fields. device. However, the face recognition device will be maliciously attacked by external users during the use process, the most common of which is that external users use face pictures or videos containing faces to attack the face recognition device, making the face recognition device Responding to these non-living faces poses a great challenge to the safety of face recognition devices. In order to prevent such malicious attacks, a face detection method and device have emerged as the times require. [0003...
