Problems solved by technology

[0003] However, the traditional liveness detection method needs to instruct the user to make an action, and it needs to repeatedly instruct the user to make an action under conditions such as non-standard user action and poor light, which makes the operation process cumbersome.

Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0033] figure 1 It is a schematic diagram of the application environment of the authentication method in an embodiment. Such as figure 1 As shown, the application environment can include a camera device 102, which can be an electronic device with a digital image capture function, for example, the camera device 102 can be used for identity authentication, such as a face recognition device, a smart phone, a tablet computer, etc. . The imaging device 102, when authentication is detected, acquires the phase difference of each pixel in the face image, which is generated base...

Abstract

The application relates to an authentication method, comprising: when authentication is detected, obtaining a phase difference of each pixel in a face image, the phase difference being generated according to data collected by an image sensor; determining depth information of each pixel in the face image according to the phase difference of each pixel in the face image; and judging whether a preset condition is met or not according to the depth information of each pixel in the face image, and if so, indicating that the living body authentication is successful. The invention further discloses an authentication device, electronic equipment and a computer readable storage medium. According to the method, the tedious operation process of a traditional living body detection method is avoided, and the accuracy of living body detection is improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to an authentication method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In some authentication scenarios, it is often necessary to perform liveness detection on users. Liveness detection is a method to determine the real physiological characteristics of the object. By instructing the user to make actions such as blinking, opening the mouth, shaking the head, and nodding, it is ensured that the user is operating as a real living person. Liveness detection can effectively resist common attacks such as photos, face changes, masks, occlusions, and screen recaptures, thereby protecting the interests of users. [0003] However, in the traditional liveness detection method, the user needs to be instructed to make an action, and the user needs to be repeatedly instructed to make an action under conditions su...
