Liveness detection method and device, and identity authentication method and device
Liveness detection and an identity authentication is included in the disclosure. A user's biological characteristic information is collected and displayed at an initial position on a screen of a computing device. A target position is determined using the initial position, and the target position is displayed on the screen. The user is prompted to move the user's biological characteristic information to cause the displayed biological characteristic to move from the initial position on the screen to the target position on the screen. The user's movement is detected and the display position of the displayed biological characteristic information is determined using the detected user's movement; a judgment is made whether the user is a living being using a relationship between the determined display position and the target position. The biological characteristic information of a living being can be verified, e.g., when the user logs in, thereby improving security.
