Customizing GINA for authentication in virtualization

GINA is a dynamic link library (DLL) and it is part of the Windows Operating System. GINA not only provides facilities for the user identification and authentication process but also provides user interface. Virtualization is a technology that allows various types of operating systems to share one computer at one time. Self-identity verification process is done in virtual machine monitor, if the user's identity has been authorize then the user is allowed to reach the image windows operating system without having to re-enter the password and userlD. This paper discusses the process of customization GINA for identity verification process without their need to repeatedly enter userlD and password, which is only done once in a virtual machine monitor.
