Abstract

The invention discloses a living body detection method and system. The method includes detecting the face area of ​​each of the user's multiple face images and extracting the person corresponding to the facial action to be detected from the detected face area. Face key points; judging that multiple face images are continuous; and based on the extracted face key points, performing liveness detection on multiple face images to determine that multiple face images are from real people. In addition, the invention also discloses a face identity authentication method and system with interactive living body detection. Through the face identity authentication method and system with interactive living body detection according to the present invention, multiple scenarios and multiple deception methods can be dealt with, thereby improving the reliability of the face identity authentication process.

Description

technical field [0001] The present application relates to the field of face recognition, in particular to a face identity authentication system with interactive living body detection and a method thereof. Background technique [0002] Face recognition related technologies have been widely used in daily life, and the safety of its use is the most concerned by people. Common methods of deception in face recognition include: photos, videos, and computer-generated face images. Among them, photos and computer-generated face images are not real faces, and faces in videos are not real-time. In some existing face recognition methods that include liveness detection, the liveness detection of faces is usually passive, such as detecting some features (facial organ feature points, statistical feature information), whether there is movement and expression changes on the face, etc. As the basic biological characteristics of a person, the face is usually not prone to major changes. If a p...
