Application Of Vein Recognition Technology In The Field Of Electronic Payment

With the rapid development of the Internet,biometric technology has been widely used in different fields.With the rapid development of biometric authentication market,from password authentication to biometric authentication,it has been widely used in various fields of society.According to relevant reports,from 2015 to 2020,the market size of biometric technology increased from US $11.24 billion to US $23.3 billion.This paper mainly focuses on the application of finger vein recognition technology in th e field of electronic payment.Taking the design of subway intelligent ticket platform as an example,the finger vein recognition technology is studied in the following steps:(1)This paper studies the basic principle and information processing flow of di gital vein image acquisition device.(2)The main work includes image denoising,geometric correction,region of interest segmentation,image normalization,and the improvement of ROI extraction method.(3)Through the simulation experiment of MATLAB software,we compare the performance indexes of fast PCA,fast PCA + SVM,2DPCA,2DPCA + SVM algorithm in finger vein feature extraction and recognition,and get ideal experimental results.(4)This paper designs the general architecture of the metro ticket pla tform,which includes three layers: information acquisition equipment layer,information preprocessing layer and data management center,and analyzes the three layers in the aspects of information interaction and data security.(5)Display the operation interface of member registration terminal,self-service ticketing terminal,database management software and finger vein identification terminal software to verify its results.The innovation of this paper includes: improving the method of locating the heigh t of ROI of digital vein;using fast PCA + SVM algorithm to extract and recognize the characteristics of digital vein for the first time in the field of feature extraction and recognition of digital vein,and achieving relatively ideal results;putting for ward the general system architecture of the platform for ticket selling of digital vein recognition type,and setting up the member registration terminal and self-service ticket selling terminal The preliminary design is carried out.
