Living body verification method and system

The invention discloses a living body verification method, which comprises the following steps that: (1) in a visible spectrum imaging picture, obtaining position data where a face image is positioned; (2) calculating the position data of the face image in an infrared spectral imaging picture; (3) calculating a face image GLCM (Ground Launched Cruise Missile) feature parameter, and adopting a SVM(Support Vector Machine) to judge whether a face is a real face or not. The invention also discloses a living body verification system, which comprises a visible spectral imaging module, a module forobtaining visible spectral image position data, a switching position data module, an infrared structure light projection module, an infrared spectral imaging module, a GLCM feature parameter module and a SVM. The method and the system have the advantages that a copycat can identity hostile attacks when the copycat uses pictures, 3D masks and the like to carry out the hostile attacks on a face-based identity verification sy
