description	The invention provides a living body detection method and device based on a face image and a server, and relates to the technical field of image detection, and the method comprises the steps: extracting a face region in a to-be-detected image; key point positioning is carried out on the face image in the face area, and identification information of each key point is generated; according to the identification information, extracting a key area, including a nose area and a cheek area, of the face image from a depth image corresponding to the to-be-detected image; respectively calculating pixel gray average values of the nose area and the cheek area and a difference value between the pixel gray average values of the nose area and the cheek area; and according to the difference value, determining whether the to-be-detected image is an image collected for the living body target. According to the in-vivo detection method and device based on the face image and the server provided by the invention, the difference val
