Research And Implmentation Of Examination Identity Authentication System Based On Finger Vein Recognition

With the development of information technology,the demand for the use of authentication technologies for accurate identification of one person becomes more and more.Traditional authentication technology due to its own shortcomings can not meet the authentication requirements,and need to adopt more convenient and reliable biometric technology.The finger vein recognition not only uses the internal body features which are difficult to copy,and also belongs to the living recognition,has a higher security and high-profile.The main thesis is as follows:By compare various biometric technologies,because of finger vein recognition have more advantages than others,we apply finger vein recognition technology in examination identity authentication system.In-depth analysis and research on the techniques used in finger vein recognition,in the image preprocessing,for the acquired finger vein image quality is poor,by use of characteristics of Gabor filter to implement finger vein image enhancement,and enhancement effect is obvious.In the feature extraction and recognition algorithm,The commonly used method of finger vein recognition based on MHD was improved,and increase the recognition rate,and for the use of single finger vein recognition feature is difficult to achieve the desired effect,propose an ensemble algorithm based on(2D)2PCA and MHD,by a variety of strategies to improve the finger vein recognition rate.In the background of the examination identity authentication system,analysis authentication systems requirements and design the system,propose a convenient and easy to use authentication system solution,and implement the system.In order to meet the demand for authentication,and implement based on finger vein recognition technology authentication platform,the platform is developed by Erlang and providing REST API.In order to facilitate the identification using finger vein authentication device,and implement based on finger vein recognition technology authentication Android APP.
