In vivo detection method, in vivo detection system and computer program product

Abstract

The invention relates to an in vivo detection method capable of realizing human body in vivo detection and an in vivo detection system employing the in vivo detection method. The in vivo detection method comprises steps that the structured light is utilized to irradiate a to-be-detected object; the first face image data of the to-be-detected object irradiated by the structured light is acquired; based on the first face image data, detection parameters indicating a subsurface scattering degree of the structured light on a face of the to-be-detected object are determined; based on the detection parameters and the pre-determined parameter threshold, whether the to-be-detected object is a living body is determined.

Description

technical field [0001] The present disclosure relates to the field of living body detection, and more specifically, the present disclosure relates to a living body detection method, a living body detection system and a computer program product capable of realizing human living body detection. Background technique [0002] At present, face recognition systems are increasingly used in security, financial and other fields that require identity verification, such as remote bank account opening, access control systems, and remote transaction operation verification. In these high-level security application fields, in addition to ensuring that the face similarity of the person being verified conforms to the base database data stored in the database, the person being verified first needs to be a legal biological living body. In other words, the face recognition system needs to be able to prevent attackers from using photos, 3D face models or masks to attack. [0003] The method to ...

Problems solved by technology

At present, there is no recognized and mature living body verification solution in the technical products on the market. The existing living body detection technology either relies on special hardware devices, such as image acquisition devices such as infrared cameras and depth cameras, or complex active light sources such as DLP projectors.
