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 present invention relates to the technical field of biometrics, and discloses a face recognition method and device. Wherein, the method includes: the face recognition device can dynamically track the eyes in the human face, and detect the blinking frequency of the eyes during the dynamic tracking process, and determine that the human face is a living body when the blinking frequency is within a preset frequency range, That is, a real human face, and when the blinking frequency is not within the preset frequency range, it is determined that the human face is a prosthesis, that is, a fake human face. Through the embodiments of the present invention, it is possible to accurately identify the authenticity of a human face through the frequency of blinking, thereby improving the security of facial recognition.

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...
