On-line palm print, palm vein image personal identification method and its special capturing instrument

Abstract

The present invention relates to an on-line palmprint and palm vein image identity identification method and a special acquisition instrument thereof. An on-line palmprint and palm vein image acquisition instrument consists of a digital video camera, a visible light source, an infrared light source, astigmatism paper, a single chip microcomputer controller, communication interfaces, a computer, an instrument bracket, an instrument shell, an instrument box and a palm box, wherein, the instrument shell is fixed on the instrument bracket, forming the instrument box in which the digital video camera, the visible light source, the astigmatism paper and the single chip microcomputer controller are arranged; the digital video camera and the single chip microcomputer controller are connected with the computer through the communication interfaces; the palm box is communicated with the instrument box. The instrument of the present invention is used to acquire palmprint images and palm vein images in higher resolution, has the advantages of real-time acquisition as well as nearly simultaneous acquisition of palmprint and palm vein images, and can meet the requirements of on-line identity identification. The image identity identification method of the present invention has better anti-counterfeiting property and higher recognition rate.

Description

(1) Technical field [0001] The invention belongs to the technical field of online identity recognition equipment and biometric identity recognition, and in particular relates to an online palmprint and palm vein image collection and recognition technology. (2) Background technology [0002] The so-called identification technology based on human biometrics refers to the use of the inherent physical characteristics of the human body (such as fingerprints, palm prints, iris, face, etc.) or behavioral characteristics (such as letters, voice, keystrokes, etc.), through signal processing and pattern The identification method to identify the technology of personal identity; compared with the traditional identity authentication method based on password or ID card, it has better security, reliability and effectiveness, and has received more and more attention in recent years. Broad application prospects; human palmprint is unique and long-term invariant. Compared with fingerprints, p...

Problems solved by technology

Therefore, using the method of palmprint combined with palm veins for identification can improve the anti-counterfeiting and security of the identification system; The acquisition of palm veins is a key technical issue; the acquisition of palm prints and palm vein information data is the basis of all subsequent processing, and its effect directly affects the accuracy of identity identification; Special equipment; therefore, designing suitable methods and equipment for obtaining palmprint and palm vein information for real-time acquisition of high-quality palmprint and palm vein images is a key technology for palm-based identification systems

[0003] The current real-time palmprint collection is mainly through the following methods: use a digital camera to obtain palm images illuminated by visible light sources, and then transmit the images from the digital camera to the computer through the communication interface; by adjusting the viewing distance and focal length of the camera, you can get clearly visible Palmprint images; this method can obtain palmprint images better, but can not collect palm vein images; although palmprint recognition has the advantages of high recognition rate and little influence from external factors, but relying solely on palmprint for identification There are certain hidden dangers in the identification method, because the palmprint is a feature of the outer layer of the human body, and criminals can easily obtain the imprint of the palmprint to copy and make fakes; performance, and can greatly improve the anti-counterfeiting and security of the identification system

[0004] In terms of hand vein recognition, there is currently only research on identification technology based on dorsal veins in China; research on identification technology based on palm veins has just started, and there is currently no dedicated collection equipment for palm vein identification in China
