Biological feature fusion recognition device and method with living body verification function

Abstract

The embodiment of the invention provides a biological feature fusion recognition device and method with a living body verification function, and the device is characterized in that the device comprises a biological feature fusion recognition main board, an image collection unit, an information interaction electronic screen, and a cavity shell; and the biological feature fusion recognition main board is electrically connected with the image collection unit and the information interaction electronic screen, and the biological feature fusion recognition main board, the image collection unit and the information interaction electronic screen are fixed to the cavity shell. The method comprises the following steps: sending a focal length adjusting instruction to calibrate the human face and eye positions by measuring the human face distance; obtaining an iris face recognition result and face body temperature information, and completing face living body detection; sending a living body verification instruction to a tester, and obtaining a palm distance; obtaining a palm vein recognition result and palm body temperature information through re-focusing; and comparing the two biological feature recognition results with the body temperature information result, verifying a living body detection result, and outputting identity information and authenticity thereof.

Description

technical field [0001] The invention relates to the field of biometric fusion recognition, in particular to a biometric fusion recognition device and method with a living body verification function. Background technique [0002] The biometric information of various modalities of the human body is mainly distributed in the face and hands. Biometric identification technology is based on the unique characteristics of the human body, such as the face, eyes, hands and body. The advanced nature of its technology lies in its accuracy and rapid identification. , wide applicability and other advantages, it has been widely used in factories and mines, prison systems, banking systems, security access control and other fields. [0003] A high-security identification system requires the ability to identify fraudulent biometric samples. This ability is often referred to as the ability to detect liveness. However, this ability is lacking or inefficient in many current biometric identifica...
