Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0051] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0052] In addition, the ...

Abstract

The embodiment of the invention discloses a living body detection method and device and a storage medium, and belongs to the technical field of machine learning, the living body detection method is used for a mobile terminal, and comprises the following steps: sending an action instruction to indicate a user to execute a preset action in a living body detection action set; acquiring a face image acquired by the mobile terminal; judging whether other actions except the preset action exist in the living body detection action set or not in the face image; and if not, determining that the living body detection is successful. According to the embodiment of the invention, the face injection attack can be well avoided, and the risk of the face injection attack is reduced.

Description

technical field [0001] The present invention relates to the technical field of machine learning, in particular to a living body detection method, device and storage medium. Background technique [0002] The application of face payment, face unlocking and other technologies in finance, security and other fields has made the requirements for face passwords more and more high, especially the problem of face anti-counterfeiting. Face anti-counterfeiting mainly refers to the use of various means (including prosthetic faces, etc.) to attack the face system, and then achieve the purpose of deceiving the system and obtaining relevant permissions. [0003] On the mobile terminal side, the basic process of face liveness detection is that the system calls the camera of the device to collect images or videos, and then the liveness detection algorithm judges whether the collected object is a living body or a prosthesis. Injection attack refers to that hackers use some means to enter the...
