Embodiment 1

[0024] According to this embodiment, an embodiment of a living body detection method is provided. It should be noted that the steps shown in the flow charts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, although in The flowcharts show a logical order, but in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0025] The method embodiments provided in this embodiment can be executed in mobile terminals, computer terminals, servers or similar computing devices. figure 1 A block diagram of a hardware structure of a computing device for implementing a living body detection method is shown. Such as figure 1 As shown, the computing device may include one or more processors (processors may include but not limited to processing devices such as microprocessors MCUs or programmable logic devices FPGAs), memory for storing data, and memory for com...

Embodiment 2

[0061] Figure 6 The living body detection device 600 according to this embodiment is shown, and the device 600 corresponds to the method according to the first aspect of the first embodiment. refer to Figure 6 As shown, the device 600 includes: a remake detection module 610, which is used to perform remake detection on an image to be detected, wherein the image to be detected contains a face image of a target object, and the remake detection is used to detect whether the image to be detected contains a remake image; blink detection Module 620 is used to perform blink detection according to the face image, and blink detection is used to detect whether the target object blinks; and a determination module 630 is used to determine whether the target object is a living body according to the results of the copy detection and the blink detection results .

[0062] Optionally, the blink detection module 620 includes: a first determination submodule, configured to determine the loc...

Embodiment 3

[0070] Figure 7 The living body detection device 700 according to this embodiment is shown, and the device 700 corresponds to the method according to the first aspect of the first embodiment. refer to Figure 7 As shown, the device 700 includes: a processor 710; and a memory 720, connected to the processor 710, used to provide the processor 710 with instructions for processing the following processing steps: remake detection of the image to be detected, wherein the image to be detected contains a target object The face image, and the remake detection is used to detect whether the image to be detected contains a remake image; according to the face image, blink detection is performed, and the blink detection is used to detect whether the target object blinks; and according to the result of the remake detection and the blink detection As a result, it is determined whether the target subject is a living body.

[0071] Optionally, the operation of blink detection according to th...

Abstract

The invention discloses a living body detection method and device and a storage medium. The method comprises the steps that copying detection is carried out on a to-be-detected image, the to-be-detected image comprises a face image of a target object, and the copying detection is used for detecting whether the to-be-detected image comprises a copied image or not; blink detection is performed according to the face image, and the blink detection is used for detecting whether the target object performs a blink action or not; and whether the target object is a living body or not is determined according to a copying detection result and a blink detection result. The technical problems that the detection time is wasted and the user experience is influenced due to the fact that a user needs to perform a series of facial actions in the actual application of a human face living body detection technology in the prior art are solved.

Description

technical field [0001] The present application relates to the technical field of computer face recognition, in particular to a living body detection method, device and storage medium. Background technique [0002] Face liveness detection is mainly carried out by identifying the physiological information on the living body. It uses physiological information as vital characteristics to distinguish biological characteristics forged with non-living substances such as photos, silica gel, and plastics. In order to ensure that you are a "live you", live face detection usually includes several identification steps, such as blink identification: for application systems that can require the user to cooperate, the user is required to blink once or twice, and the face recognition system will automatically identify The change of the opening and closing state of the obtained eyes is used to distinguish the photo from the face; or the mouth opening and closing discrimination: similar to th...
