Problems solved by technology

[0006] However, whether it is a real person or a photo taken by a camera, the final result is a two-dimensional picture. Therefore, it is difficult for current face recognition technology to judge whether it is a real person or a photo in front of the camera.

Embodiment Construction

[0045] In order to improve the accuracy of human face detection and the security of an identity authentication system, embodiments of the present invention provide a human face detection method, medium and related devices.

[0046] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention, and in the absence of conflict, the present invention The embodiments and the features in the embodiments can be combined with each other.

[0047] The inventors found that in the existing human face liveness detection methods, the way of command and action coordination is generally used, such as face turning left, right turning, mouth opening, blinking, etc. If the command coordination is wrong, it is considered as forgery and deception. However,...

Abstract

The invention discloses a face living testing method, a medium and a related device, thereby improving accuracy of a face living testing result and safety of an identity identification system. The face living testing method comprises the steps of predicating a to-be-tested object by means of a pre-trained living predication model, wherein the living predication model is obtained through training sample data which are acquired by an infrared image acquisition device by means of at least one clustering algorithm, the sample data comprise living sample data and false sample data; and determiningwhether the to-be-tested object is a living object according to a predication result output from each living predication model.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a method, medium and related devices for detecting human face liveness. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In the biometric system, in order to prevent malicious parties from forging and stealing other people's biometrics for identity authentication, the biometric system needs to have the function of living body detection, that is, to judge whether the submitted biometrics come from a living individual. [0004] General biometric living detection technology utilizes people's physiological characteristics. For example, living fingerprint detection can be based on information such as finger temperature, perspiration, and electrical conductivity. Li...
