A Biometric Approach to Linux Login Access Control

Login access control refers to securing the entry point to a computing system. The login system is responsible for this service and must provide a number of tasks, the main task being that of user authentication. Traditionally, the authentication in Linux and other operating systems is achieved through password verification. This research focused on overcoming the vulnerabilities of password verification, which has been identified as the greatest gap in computer security, through the development of a biometric (facial recognition) login system. The application of biometrics, the automated use of physiological or behavioral characteristics to determine or verify identity, was applied via the eigenface algorithm successfully in this research, resulting in a functional prototype biometric login system for Linux
