Embodiment Construction

[0046] Face recognition technology is a branch of biometric technology. Compared with iris recognition, fingerprint scanning, palm scanning and other technologies, face recognition technology uses a general-purpose camera as an identification information acquisition device, which can be completed in a non-contact manner. identification process. At present, with the gradual commercialization of biometric recognition technology in security systems, and toward the trend of automation and unsupervised development, although the current face recognition technology can identify the identity of the face image, it cannot accurately identify the true face. fake. As a result, attack methods against this face recognition system are also emerging in an endless stream, and liveness detection is the main means to prevent attacks.

[0047] During the research process, the inventor found that a CNN-based dual-stream live face detection is currently proposed. By extracting local features and o...

Abstract

The embodiment of the invention provides a living body judgment method and device. The method comprises the steps of obtaining a human face eye region of a to-be-recognized target in an infrared scene; inputting the human face eye area into a pre-configured living body recognition model for recognition to obtain a recognition result; and judging whether the to-be-identified target is a living bodytarget or not according to the identification result to obtain a judgment result. Therefore, the face living body judgment can be simply and efficiently carried out, so that the authenticity of the face is accurately distinguished, the security system is prevented from being attacked by lawbreakers through face duplication and spoofing, and the security in a security scene is further improved.
