Abstract

The invention discloses a living body identification method and device, which belong to the field of biological feature identification. The method includes: providing lip language prompt information to the identified object; collecting at least one frame of image of the identified object; when the lip change is included in the at least one frame of image, detecting whether the lip change matches the lip language prompt information; If the lip change matches the lip language prompt information, it is determined that the identified object is a living body. The invention detects whether the lip change matches the lip language prompt information; it solves the problem that if an illegal user puts a photo of a legitimate user in front of his face, he can still pass the identity authentication, resulting in potential safety hazards; The effect of identifying whether an object is alive or not.

Description

technical field [0001] The invention relates to the field of biological feature identification, in particular to a living body identification method and device. Background technique [0002] With the development of biometric identification technology, face recognition method has become a common method to confirm the identity of users. [0003] In the prior art, some face recognition methods have added a live face identification method, which can perform better face detection and recognition. A current face identification method uses an auxiliary light source to detect temperature using infrared thermal imaging to determine whether the object to be identified is a living body. [0004] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: due to the good penetration of thermal imaging, if an illegal user puts a photo of a legitimate user in front of his face, he can still pass the identity auth...
