Face indentification device for live person

Abstract

The invention relates to a face indentification device for a live person and belongs to technical field of the face indentification. The face indentification device for the live person comprises a light source, a barrier panel, a vidicon, and a computer. The computer is respectively connected with the vidicon and a light source. Light beams sent by the light source are kept out by the barrier panel. The light beams can be turned into parallel equal separation stright line fringe patterns and can be reflected on surface of the indentified subject. The vidicion can convert an image of the identified subject to a digital image and output the digital image to the computer. The face indentification device for the live person can identify the faces of the live persons, static graphic photos, and dynamic screen images by utilizing stright line fringe patterns which are sent out. Accuracy rate of the identification is very high. Compared with prior art, the face indentification device for the live person can identify the face without a person identified changing face expression to coordinate the identification. The defect which the existing technology can only identify the static photos and cannot identify the dynamic screen images is resolved. The face indentification device for the live person enhances security and convenience of a face indentification system. The face indentification device for the live person has the advantages of being simple in structure, reliable in operation, rapid in indentification, and easy to carry out.

Description

technical field [0001] The invention relates to a living body face identification device, in particular to a living body face identification device used in a face recognition system, and belongs to the technical field of face recognition. Background technique [0002] Face recognition technology identifies people's identities by analyzing and comparing facial biometric information. Compared with other biometric authentication technologies, face recognition is a non-invasive identification technology that is more direct, more convenient, more friendly, and easier to be accepted by people. With the widespread application of face recognition authentication systems, there have been security incidents that illegally use legitimate user photos to pass identity authentication. [0003] In order to identify real people and photos, some face recognition systems have added a live face recognition function, which determines that the recognized object is a live real person through the ...

Problems solved by technology

[0003] In order to identify real people and photos, some face recognition systems have added a live face recognition function, which determines that the recognized object is a live real person through the facial expression changes (blink or smile) of the recognized person. This live face recognition method exists The following disadvantages: need to do a lot of facial expressions and actions on the face of the person to be recognized, the human-computer interaction method is not friendly, it is easy to make the user feel bored, and the algorithm is complicated, which reduces the speed of face recognition; moreover, if using a tablet or laptop , when playing video images of legitimate users, the identity authentication can still be passed, leading to security incidents
