Problems solved by technology

[0003] In recent years, in the development process of face recognition technology, deception of face prosthesis has appeared continuously, such as using projection, liquid crystal display and other playback devices to display face images on the screen to make three-dimensional models of faces , and then place the face image or three-dimensional model displayed on the screen of the playback device in front of the acquisition device of the face recognition system, so that the face prosthesis can also be recognized and passed, thus bringing certain benefits to the society. Security risks

Abstract

The embodiment of the invention relates to the technical field of biological recognition and discloses a face recognition method and device. The method comprises the following steps: the face recognition device can dynamically track the eyes in a face and detect the blink frequency of the eyes during a dynamic tracking process, determining the face as a living body, namely a true face, when the blink frequency is within a preset frequency range, and determining the face is a false body, namely a false face, when the blink frequency is not within the preset frequency range. According to the embodiment of the present invention, the authenticity of the face can be accurately distinguished by the blink frequency so that the safety of the face recognition can be improved.

Description

technical field [0001] The invention relates to the technical field of biometric identification, in particular to a face identification method and device. Background technique [0002] Face recognition is a kind of biometric recognition technology based on human facial feature information for identification. With the development of its technology and the improvement of social recognition, face recognition is now used in many fields, for example, face recognition anti-theft doors, face recognition access control and attendance systems, public security and criminal investigation for hunting criminals, etc. [0003] In recent years, in the development process of face recognition technology, deception of face prosthesis has appeared continuously, such as using projection, liquid crystal display and other playback devices to display face images on the screen to make three-dimensional models of faces , and then place the face image or three-dimensional model displayed on the scre...
