Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the invention, not to limit the utility model.

[0039] The invention proposes a method and a system for preventing photo and video spoofing attacks that can be used for identity authentication applications based on face recognition on a mobile platform. In identity authentication based on face recognition, real faces have 3D features. If it is a real face, when the camera on the mobile device captures the video of the face during motion, it will capture different angles of view of the face at different positions, that is, the head posture, and the displacement of the mobile device is related to the head posture. The change of satisfies the geometric relationship of the chord length formula, such as figure 1 As shown, the face faked by the ph...

Abstract

The invention provides a liveness detection method and system for face recognition on a mobile platform. The method includes the following steps that: a facial video containing of user photos at different angles as well as motion acceleration and rotation data of a mobile device in video recording are captured; the feature information of the correlation of head pose vector data and device movement vector data in the video are calculated and extracted; and whether the detected video is a real face or a face counterfeited from photos / videos is distinguished through a classifier. With the liveness detection method and system of the invention adopted, a face recognition-based identity recognition application on the mobile platform can resist photo and video-based spoofing attacks, and hardware devices which most mobile devices are not provided with are not needed to be adopted. The method and system have robustness for complex light conditions and can tolerate head rotation of the user in a use process.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a living body detection method and system for face recognition on a mobile platform. Background technique [0002] Face recognition is a biometric identification technology based on facial features, which conforms to the way humans distinguish between different faces and identities, and has user-friendly features. Therefore, the face recognition system is widely welcomed in the real world, especially widely used in the user authentication system on the mobile device (mobile phone, tablet computer, etc.) platform. For the face recognition system, the most common attack is a spoofing attack (spoofing attack), in which an attacker uses a legitimate user's face picture and video to forge the user's face features to attack. As more and more users publish a large number of personal photos and videos on online platforms such as social networks, the threat of spoofing attacks i...
