Embodiment Construction

[0061] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0062]The wrist vein authentication system firstly designed the wrist vein image acquisition device after studying the camera, light source and filter, and collected images that meet the experimental requirements after repeated tests and adjustments. Then the process of image preprocessing and feature extraction is completed by programming in Matlab language. Finally, the extreme learning machine is used to complete the classification and recognition of vein images, and a graphical user interface is designed to show the functions of the system. Experimental results show that the recognition accuracy of the system is above 95%. The overall framework of wrist vein authentication system design is as follows: figure 1 .

[0063] The image acquisition module collects wrist vein infrared images through the wrist vein acquisition device;

Abstract

The invention provides a wrist vein certification system, which is characterized by comprising an image acquisition module, an image preprocessing module, a characteristic extraction module and a recognition module, wherein a collected image is preprocessed to obtain a clear image with obvious characteristics; various image characteristic extraction methods are analyzed, and main ingredient analysis and wavelet analysis are adopted to extract image characteristic after practical situations are considered; the images are classified by adopting an extreme learning machine; an optimal parameter is selected after the comparison of various experiment results; and a recognition rate is above 95%. The system has the advantages of being simple in operation and high in robustness since the main ingredient and the high frequency and low frequency characteristics of image information are used for recognition.

Description

technical field [0001] The invention relates to a wrist vein authentication system. Background technique [0002] Vein authentication technology is a technology that uses veins under the skin as identity features for identification. Since the human veins are hidden under the skin, it is not easy to forge, so the vein feature recognition technology is a highly secure identification technology and has a good application prospect. [0003] Modern society has put forward newer and higher requirements for information technology. For example, computers make economic and financial networks, and network economics and finance require more reliable information security systems. Authentication is one of the basic methods people use to enhance information security. Traditional identity verification is based on identifiers (such as certificates, keys, etc.) or knowledge (such as passwords, PINs, etc.), but these methods are inconvenient, unsafe, and unreliable. The disadvantages are se...
