Design And Implementation Of Windows Networked Login Method Based On Fingerprint Recognition

With the development of network and information technology,computer information security has become the focus of attention.As the most popular computer operating system,the research and security of Windows system is very important for computer information security.Login authentication is the most basic and important security mechanism in Windows system.The method of login by user password is widely used in Windows operating system,but for many public computers in the laboratory,using this login method,authorized users need to remember a large number of computer passwords.At the same time,passwords are prone to security risks such as theft and cracking,which can not guarantee the security and convenience of login.With the development of biometric authentication technology,Microsoft introduced Windows Hello function into Windows system.Users can add fingerprints,faces,iris and other biological features to Windows system.The system logs on to Windows system by verifying the user's biometric features.However,the Windows Hello function requires that the computer device must have the corresponding hardware support.At the same time,the authentication method is limited to the user who registered biometrics locally to log on to the computer device.For many public computers in the laboratory,if the fingerprint authentication method in Windows Hello function is selected,each authorized user needs to register his own fingerprint information on authorized computer equipment.Moreover,the limited number of fingerprint information registered on each computer device brings inconvenience to user login and inconveniences to the centralized management of laboratory administrators.In view of the above problems,this paper designs and implements a Windows network login management system based on fingerprint recognition.The main work is as follows:1.By studying the credential provider login model of windows,this paper introduces the fingerprint authentication mode into the credential provider,and combines the network login management mode,puts forward a scheme of windows network login system based on fingerprint recognition.This scheme realizes the unified management and authorization of the computer equipment of the user login laboratory on the server side.2.According to the above system scheme,the fingerprint identification credential provider module of Windows system and server-side authentication management program are designed.The centralized management of client-side login authentication of Windows system is realized by using C/S mode.At the same time,the Web information management system is designed based on the framework of SSM by using B/S mode.The management of laboratory user information and the allocation of equipment privileges are realized.3.The realization of fingerprint identification login credential provider module on Windows system,server-side authentication program and Web-side information management system is completed.The experimental environment is built and the functions of the system are tested.Through testing,the unified management and authorization of user login authentication can be realized on the authentication server side.At the same time,the Webside information management system can realize the management of user information and the allocation of device privileges.
